Hello!I'm working with STM32G0B1 MCU and using CubeMX, I've enabled RCC_MCO for PA9 pin (HSI 16 source, 128 as prescaler) and a simple Input for PA8 pin. The code was generated to CubeIDE and "SystemClock_Config" function calls this method at the end: HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSI, RCC_MCODIV_128); But I noticed that both PA9 and PA8 outputs 0.125 MHz, even "MX_GPIO_Init" function setting correctly the pins!Searching on HAL files, I found that "RCC_MCO1" defines to "RCC_MCO_PA8", so CubeMX should config MCO as "RCC_MCO_PA9".Can we confirm this as a bug?

I have a problem with handling multicast frames. I think it's a server side problem and how to read multicast frames in the lorawan stack? The same as unicast frames? I added support for multicast frames in TTN according to https://www.thethingsindustries.com/docs/devices/configuring-devices/multicast/. Is there an example? Multicast frame support with server?

Hi @everyone  i completed the CAN2.0A based communication. Now i want to learn about CAN2.0B that is 29-bit identifier. so can you please provide the example if available for my reference.

I am trying to use the X-NUCLEO-IHM07M1 motor development kit with a custom FPGA pwm controllerI am just trying to spin a motor in open loop and no feedback or speed controlI am planning to feed the 3 phase pwm signal to IN1, IN2 and IN3 and supply 9v to the IHM07M1 board.Im wondering what else i need to take care of , any enable signals to be toggled ?what is the role of ENx signals are they to be toggled with the INx pins ?

Dear  STM：        We have the following questions to consult：         ①Does the PA10 of STM32MP157AAD3T have a pull-up resistance inside the OTG_ID pin function?Do I need an external pull resistor when doing OTG ID function at the same time?If so, what is the resistance value of the external pull-up resistor?        ②What is the maximum capacity supported by the emmc chip attached to the EMMC interface of STM32MP157AAD3T?       ③When the emmc interface of STM32MP157AAD3T supports the speed of HS200, what is the power supply mode of the external EMMC chip? Our power supply method is shown in the attached picture, please help evaluate whether it can be satisfied. If not, could you recommend the design schematic diagram of EMMC supporting HS200 speed？     ④Could you provide the reference design of STM32MP157AAD3T？  &

Hi,MCU planned to use - STM32U5G7VJT6QPlanning to use PD12,PD13,PE0,PE3,PC7,PE5 as encoder and hall sensor pins as shown below in the image.But these signals are 5V logic. Is it okay if we give 5V to these pins?In datasheet it is mentioned as 5V tolerant pins(FT_h). Does it affect its performance? any AC/ DC characteristic issue will rise because of this. Please confirm.Or suggest which pins can be used or any other alternate way. Also the possible failure cases.  

Hey there,im currently trying to debug a small project, where I use a Timer to Read 5 ADC values every second and store them to an array via DMA.While debugging, I couldn't figure out how to display an array in the expression viewer. I saw some videos which suggest, that the IDE automatically detects an array when entered in the expression, but that isn't the case with me.As the flash memory of my mcu is rather small, I have to build the project with optimization to build without errors. I tried -Og, -O1 and -Os, which doesn't affect my problem.If anyone has an idea how I could fix this, I would be very happy. I'm attaching my code from the variable declaration and a screenshot from the expression viewer.If i missed to provide any important information, please let me know.  /* Private define ------------------------------------------------------------*/ /* USER CODE BEGIN PD */ #define ADC_BUFFER 5 #define REFVOLTAGE 3000 /* USER CODE END PD */ /* Private macro -------------

Hi, can someone help with ADS124S08 SPI ADC and its linux driver? I think the driver is correctly probed. I see /sys/devices/platform/soc/44004000.spi/spi_master/spi0/spi0.0/iio.device0/in_voltage0raw ...etc but it seems the device does not reply.This is my device tree configuration:&spi1 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&spi1_pins_a>; cs-gpios = <&gpioz 3 GPIO_ACTIVE_LOW>; #address-cells = <1>; #size-cells = <0>; adc@0 { compatible = "ti,ads124s08"; reg = <0>; /* CS #0 */ spi-max-frequency = <1000000>; spi-cpha; reset-gpios = <&gpioi 2 GPIO_ACTIVE_LOW>; }; };First, i don't see the cs going low when i try to read the voltages. Should the driver do that?Second, the driver ti-ads124s08.c itself seems a bit incoherent with the datasheet. it defines the start conversion command as in the datasheet but then never uses it and instead it uses a made-up command.#define ADS124S08_CMD_START 0x08 #def

Hello everyone,I want to develop a project for STM32MP1 using stm32cubeIDE Version: 1.15.1. In the yocto-related part of the topic, I successfully compiled a kernel and produced an SDK for the relevant kernel. I want to import this SDK into the cubeide environment and start with a ledBlinky application. But I couldn't import the SDK.I have reviewed what is explained in forums and blogs, but I constantly encounter error messages. Below is the location of the .sh file of the SDK I produced.                                                And I keep getting the following error. What I want to do is to use my own SDK for mickledore, not the SDK offered by ST.Sinceley

I have an STM32F407 Discovery board. My project works fine using the dicovery board.Now it is time to move it to my own PCB, using a STM32F405.As a board "bring up" I tried to run a simple LED toggle program. When I flash the program I get a Download verified successfully message.It does not work unless I step through it in debug mode. In run mode the output pin for the LED stays high. If I add a variable and increment it every time the LED toggles I can see it incrementing normally in debug mode.I have an external resonator crystal at 8MHz. I can see it working at 8 MHz on the scope.I have a 10K resistor pulling BOOT0 to ground. The two VCaps are present. A 10k resistor pulls NRST up to 3.3v rail.All power and grounds ok with decoupling caps.I have checked all settings in my .ioc file. Cant see any issues. (The settings are the same as for my discovery board program that works correctly).Im sure one of you can help. Thanks in advance...

I have this timer that is configured to generate an interrupt after every 15.625 µs, i.e., when it’s period elapses. The timer elapsed callback function contains the code below. The requirement is that new data be transmitted via SPI every 15.625 µs but a single iteration of this callback function is taking 17.95 µs currently. The clock speeds are at the maximum frequency I can achieve with the internal clock. I’ve also tried to reduce the length of the code as much as I can (There’s no code in while (1)). I believe if I use an external oscillator to achieve a higher SYSCLK frequency, the callback execution time will reduce. I wanted to know if there’s anything else I can try before redesigning the board. void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if (htim == &htim2) { DAC_EN; HAL_SPI_Transmit(&hspi1, &wave_data[index], 3, 1); DAC_DIS; index += 3; if (index >= 1535) { index = 0; } } }

I have the FMAC working enough to produce values readable from RDATA, but they are acting strangely and giving small positive and negative values and 0. As a minimal test, I created the below code to have X1 and X2 be all 1s. A buffer length of 18 should produce an FIR result of 18.  The below code produces a result of 0 which I read out via STLink from an unused register on TIM20.If I let my code to progress such that X1 contains real changing data, the RDATA value changes minutely above and below zero.I suspect I have addressing errors of some sort, but if I loaded only 1s into everything, I should still get 18...?Did I miss anything in the below code? //FMAC ConfigFMAC->X1BUFCFG = 0x000012DC; //no threshold, 18 buffer length, 220 as base address.FMAC->YBUFCFG = 0x000001FF; //no threshold, 1 buffer length, 255 base address.FMAC->CR|=0x00010000;//reset//write X2 vectors..18 long 12 total: 0-204 in FMAC memfor(int i=0;i<12;i++){FMAC->X2BUFCFG = 0x00001200+i*18;

I'm rewriting some of my old LL code to use HAL and having trouble getting the RTC to read time correctly. I have a simple test project where I'm calling HAL_RTC_GetTime() and HAL_RTC_GetDate() before and after a call to HAL_Delay() with the expectation that the difference in the 2 RTC calls will be something close the the HAL_Delay but that isn't happening.  I running on a custom SOM we've developed that uses a STM32H7A3LIH6Q with a 24 MHz HSE crystal and a 32.767 kHz LSE crystal. Here's my code:  #include "main.h" #include "rtc.h" #include "gpio.h" void SystemClock_Config(void); int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_RTC_Init(); /* USER CODE BEGIN 2 */ RTC_TimeTypeDef newTime1; RTC_DateTypeDef newDate1; RTC_TimeTypeDef newTime2; RTC_DateTypeDef newDate2; //Delay to get some non-zero value in newTime and newDate HAL_Delay(4500); //Initialize newTime1 and 2, newDate1 and 2 HAL_RTC_GetTime(&hrtc, &newTime

Hello All, I am new to the STM32 platform and trying to learn.  I am working with a STM32F070F706 MCU.  I would like to use the MCU internal clock to support my peripherals  (I2C and USB 2.0).  The clock configuration tool cannot resolve the issue itself, so I modified the prescalers on my own and the issue seems (to me) to be gone. However,  if I select. "Resolve Clock Issues", STM32CubeIDE tells me it can't find a solution.  It will generate code for me, but warns me:  "- Main Config: These peripherals still have some not configured or wrong parameter values: [Clock]".  Does anyone see an issue with the clock configuration shown below?  To me, everything seems to be configured satisfactorily.  

I'm the hardware guy on a 32F413 project where we have a lot of impulse noise nearby on the PCB.  Because of this I've been on a campaign to make certain that all microcontroller I/O pins are equipped with pull-up or pull-down resistors.The project has reached the stage where our quality assurance folks get cranky whenever I try to add a resistor to this PCB.  So when I find a 32F port pin that is missing a pull up/pull down resistor (as I did this week) it becomes a crisis of meetings and memos.Remind me to never work again in a medical equipment company.So I approached our firmware guy and asked him to alter his code to make certain the offending port pin is equipped with either an internal pull-up or a pull-down during his sleep mode,Firmware guy replies:  "No can do, hardware guy.  The micro is in its deepest sleep state and the port pins flap in the breeze during deep sleep.  You must fix that undefined I/O state with an external resistor. Luv ya, big guy.

I am facing an issue with my custom-made STM32F4x minimum system board. I am experiencing unstable connections with the STLink. I am using an AMS1117 for power supply, and I have found that when the STLink supplies power at 5V to the AMS1117, it cannot connect properly. Similarly, when I directly connect the 3.3V output to VDD, it still does not connect properly. Although all the voltage readings at various points are correct (VDD is 3.3V, and VCAP is 1.25V), I cannot establish a connection with the STLink. However, the STM32 is booting up normally, and the LED flashing program I previously burned is running. Additionally, I can connect and burn using the serial port, but only the STLink connection fails. I have also tested reducing the SWD frequency to 5kHz, but it still cannot connect. The logic analyzer shows some errors and no replies in the SWD response, but there are a few ‘OK’ responses as well. Occasionally, I find that I can connect properly, but it seems to happen randomly wi

I recently got a STM32F410RB. The block diagram shows "DAC1 as AF". I have been looking up the datasheet to find the alternate function pin for the DAC module in the "Alternate function mapping" table, but I'm unable to. Also, I see DAC1_OUT under the Alternate function column of the "Pin description" table. I am unable to ascertain the AF type hence. Any help would be highly appreciated. I am very new to STM32 programming, and have done it using the registers (no HAL).Here is the datasheet I'm referring to: https://www.st.com/resource/en/datasheet/stm32f410rb.pdfThanks!

Hello forumI'm trying to implement a project that takes the sensor data and saving it into a USB flash Drive,for that, I'm trying to use the MX system to activate:USBPD - Type C only, TIM2, enabled USB support USBX - Host CoreStack FS, Host Controller FS, MSCUSB_OTG_FS - Host OnlyFileX - FileX Corewhile creating the files, before even editing anything, I get a contradiction error between ux_port.h and fx_port.h,if I try to delete one of them it disables the entire respective library.Is there anything I'm doing wrong? any working example of what I'm trying to do?I really appreciate any help you can provide. 

I am using STM32H743IIT6 MCU to drive HDMI display using LTDC peripheral and Texas Instrument TFP410 for RGB to HDMI conversion. Issue I am facing is I use external crystal as clock source then I see disturbance on my HDMI monitor and its display blinks randomly, say screen is proper for some 5-10 sec then it will flicker and turn off and on then again be stable for some time and these repeats. My guess is that some HDMI timing related parameters are not matched and that's why this behavior on monitor. Surprisingly, this issue resolves if I use internal CSI RC oscillator as clock source.  I even tried doing the PCB layout again using an external agency, but same issue persists in that layout as well. What could be the issue here that it works with internal CSI RC clock source and not external crystal ? Please find below related parameters configured in my project. I have also attached my projects CubeMX .ioc file for reference.Clock Source: External Crystal 25MHzFMC: External

Can failed to reinit after deinit. 1. Two cans was used for my projects which was generated by stm32cubemx 2. after run for a short while , I turn off both cans by HAL_CAN_DeInit 3. then I reinit both cans by MX_canx_init and found it failed in HAL_CAN_Init 4. I have tried to pull both can rx and tx pins but does not work 5. Before reinit I have checked both rx and tx pins is high Questions: 1. Possible reason for can reinit failed. 2. Any checlist for reinit?   Thank you & BR

If the LSE 32.768KHz crystal is disturbed after the system starts with MSIS auto calibration, and the MSIS clock is used by the PLL for the SYSCLK, the frequency of SYSCLK loses its 0.25% accuracy and starts to drift.Is there any register or interrupt that can be used to detect this situation (MSI_PLL_UNLOCK and LSECSS not available for Rev X - RM0456 Table 184 & 187), and if so, what steps can re-setup the clock to be auto calibrated once again?I can simulate it by touching the LSE crystal when it is running, the SYSCLK changes from 159.91Mhz (stable) to about 161.59 - 161.2 (unstable), even though the 32.768khz returns to being stable after the disturbance.I am currently evaluating using both the NUCLEO-U575ZI-Q board and the B-U585I-IOT02A board, both with Rev X parts fitted. Is Rev X currently in production, or is there a newer/fixed revision available?

Hello @STTwo-32 ! Thank you so much for clarifying everything! I am really thrilled with the STM32WBA Nucleo board. Could you please let me know, if it is compatible with the FP-AUD-BVLINKWB1 pack? If not, are there any code examples on how to implement Bluetooth audio on it? Such as pairing with headphones et cetera?  

Hello,I am using the STM32CubeIDE to write software to test the STSAFE (Nucleo-F401RE + Nucleo-SAFEA1). I am trying to get a basic software working and trying to use one of the STSAFE functions, but I am running into a strange error when I try to compile it. Based on all the searches I've done, this is typically a linker issue. However, I verified that the file that declares this function. I think I'm getting tunnel visioned, but I cannot see what part I haven't linked properly. Does anyone know where else to look? Open Declaration:
