Can anyone please direct me to documentation on how to interface to Bluetooth functionality on the STM32WB1MM module (or B-WB1M-WPAN1)? My understanding is that I should be able to use the Bluetooth capability from either the on-board STM32WB15 of from an external MPU via TTL UART or SPI. The question is how? I have found and read all manner of documentation about the STM32WB1MM and B-WB1M-WPAN1 devices but cannot find anything pertaining to Bluetooth. I have also looked through the example projects on GITHub but struggle to navigate the bewildering number of projects having rather cryptic names. https://github.com/STMicroelectronics/STM32CubeWB/tree/master/Projects/B-WB1M-WPAN1/Applications/BLE/BLE_HR_p2p_Sensor Is it just a question of connecting and using AT commands? Thank you.

Hello,I am using a STM32H747i-DISCO kit and have set up a project based on the TouchGFX Designer demo applications, which works based on a single framebuffer.If I go into the CubeMX settings and set the framebuffer strategy to "Double Buffer" and the buffer location to "By Allocation", I can see my screen after flashing, but it is frozen. According to TouchGFXGeneratedHAL.cpp the video RGB buffer (1,152 Mbyte for 800 x 480 x 3 bytes) is located at 0xd0000000 in SDRAM and the framebuffer is placed at 0xd0119400 right after the video buffer. The pointers are set accordingly in the TouchGFXGeneratedHAL::initialise() by calling setFrameBufferStartAddresses((void*)frameBuf, (void*)(frameBuf + sizeof(frameBuf) / (sizeof(uint32_t) * 2)), (void*)0);.What causes my display to freeze when I change to double framebuffer? 

I have STM32F4 DISC board and I worked with it several weeks. It was working correctly but today when I was set a SPI connection with other stm32f030 mcu, I plug-in and plug-out usb cable and I got "USB device not recognized" error message.I didn't change anything. When I was plug-in, power led on board lighting dimly. Is this a sign for corruption of card??stm32cude ide can not detect stm32 disc board.Thanks for any help 

I would like read the gpio lines at fastest speed. As example it is possible to read first 4 ports by reading:uint16_t ports0123=GPIOC->IDR&0x000F; (it is very fast, takes 28 tics)It is possible to read ports GPIO_PIN_0-15 by connecting GPIOC->IDR to a DMA?and a fast DMA? 

From AN5185 I understand that up to 100 keys can be send to FUS for storage, but any index will only be written once. So once I have reached 100 writes, e.g. because I have constant pairing keys between devices but I allow to disengage and reengage such pairings, I can no longer save any keys in FUS and would have to rely on handling by CPU1. Is this correct?

Hi everybody, Actually I start a new project with a ST7567 driver for LCD 128x64. I have create my project with CubeIDE . CubeIDE generate my code in the main.c  like this :    /* Private variables ---------------------------------------------------------*/ RTC_HandleTypeDef hrtc; SPI_HandleTypeDef hspi1; /* USER CODE BEGIN PV */ /* USER CODE END PV */ /* Private function prototypes -----------------------------------------------*/ void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_RTC_Init(void); static void MX_SPI1_Init(void); /* USER CODE BEGIN PFP */ /* USER CODE END PFP */     It's ok . Now to drive my screen I would like to create files like st7567_driver.h and a st7567_driver.c file.This way I could create my functions relating to the driver in these files. Functions such as "draw pixel", "send command", "send data", etc....But to communicate with the driver I have to use SPI1 create

I've found a bug in the analog clock widget. It works perfectly, except when passing midnight, then the arms go all over the place. I think they go in the wrong direction first and then bounce a few times. I've attached a video and an example project. Glitch occurs in simulator and on board.

Hi there,I want to try touchGFX on my homemade board with the STM32F429BIT6 and a band flash chip H27U1G8F2B.After config by cubeMx and TouchGFX designer, my demo can work as well.However, I checked the map file and found the image is still stored in the internal flash.Need I change the "config.hpp" file to complete this function?How can I restore the data to external NAND flash?Could this step be done automatically, or need some tools to finish it?If possible, please give me some documents about it.Thanks for your help!

Hi,I'm trying to create my custom UART firmware on STM32F3DISCOVERY board. Since I wrote the Transmit part of the driver and I verified that it continuously writes words to the USART_TDR register, I was going to check whether the UART messages are actually outputted from the MCU pins.So far the plan is just to continuously spam some messages via PC4 pin to the on-board ST-link debugger. Since I know that I have a PCB version C, the on-board debugger should be of version ST-LINK/V2-B, meaning that it has virtual COM port interface on USB.My main question is, do I understand it correctly, that just by sending  some UART messages from the MCU pin PC4 to debugger, the virtual COM port of the debugger shall automatically re-send these messages to a PC, where I should be able to read them with some UART compatible terminal (e.g. PuTTy, Serial Debug Assistant, etc.)?Or am I missing some more steps? Like, are there some other steps involved to make the on-board debugger to re-send UART me

We are using the STM32H745I_DISCO and a custom daughterboard.  We use the Arduino Connectors to interface to our daughterboard.  One of the signals on CN7 pin 6 is default jumpered to PC3_C on the processor.  We cannot get it to work at a digital push-pull GPIO.  All of the other GPIOs work as we expected. We have checked our code against another similar case and it appears to be the same.  We are wondering if this might be because PC3_C cannot be used as a GPIO and is only analog or the following alternate functions listed in the STM32H745xI/G datasheet.C1SLEEP, DFSDM1_DATIN1, SPI2_MOSI/I2S2_SDO, OTG_HS_ULPI_NXT, ETH_MII_TX_CLK, FMC_SDCKE0, EVENTOUT Can someone confirm if the PC3_C can be used as a GPIO or not, and if it can, anything we might be missing to get it to work.  Also, what is the "_C" meant to differentiate (from say the other PC3 function). Thanks

Hi,I started working on STM32C011J4.Systick, PWM, ADC, GPIO works just fine. Set pin4 to NRST_MODE 2 via STM32CubeProgrammer (v2.15.0) as GPIO. MCU gets stuck at reset if pin4 is low at power on reset. After applying 1.4V or higher to it momentarily (even leaving it floating), MCU starts running and pin4 acts as GPIO, no reset functionality until next power cycle.Any thoughts?Thanks,Tim 

Hi supporter,I'm developing STM32H573I-DK and trying HAL_ETH_ReadPHYRegister to check link status. But this API seems be changed.Previous prototype is:HAL_StatusTypeDef HAL_ETH_ReadPHYRegister(ETH_HandleTypeDef *heth, uint16_t PHYReg, uint32_t *RegValue)But now is:HAL_StatusTypeDef HAL_ETH_ReadPHYRegister(ETH_HandleTypeDef *heth, uint32_t PHYAddr, uint32_t PHYReg,uint32_t *pRegValue)I have no idea what PHYAddr is. And PHY_BSR is also not defined in STM32H5. So, I don't know how to fill PHYReg. Is there any example? I've referenced to GitHub - STMicroelectronics/STM32CubeH5.But there are no examples about this API. Thanks for your help.

I want to output a static DC value from an STM32G473 DAC, but I’m seeing the output value has a noise tone on it that changes amplitude and frequency depending on various other settings. The behavior reproduces with all other peripherals disabled.  Here are observations and questions: I’m using VREFBUF in internal reference mode. Setting the DAC (1CH2,2CH1,2CH2) output to max makes the waveform bottom sit just below the VREFBUF value, and the peak waveform output goes above the VREFBUF value. This should not be possible, but its what I’m measuring. What could I check on to figure this out? With the output buffer enabled, the noise amplitude is a bit less than 1v peak to peak. If I remove the output buffer, it drops to less than 0.1v. The DAC outputs directly to a scope probe, so I don’t understand why it would behave this way. Of the three internal VREFBUF settings, the lowest one produces the highest amplitude noise tone and the lowest frequency, the high setting p

We have a design based on the STM32G0B1CET6 MCU.Recently we noticed some failing parts after power on/off testing. Symptoms: software is no longer running and the SWD port is not responding. We sent the broken parts to ST for analysis. The report (C241043257) showed that the FLASH status register has bit 15 (OPTVERR) set. This indicates a mismatch on option byte loading, which can be caused by a reset or glitch during the option byte programming phase.After analyzing our code, we found that at each startup the firmware writes 0xBB to the RDP option byte.We are quite sure this caused the issue, but what we would like to have confirmed is:If 0xBB is written to the RDP option byte, while is already set to 0xBB – will that still make the chip vulnerable to a reset or instable power supply? A related question:At the end of a firmware update, we do a bank swap, which requires writing to an option byte. That will also introduce a brief moment where the chip can be bricked if power supply

Has multiple failures to download HAL package of about 100 MB to 500 MBfrom ST web.  Firefox said failed, at about 20% progress bar.  Saw same on multiple different packages.  Seem it timeout on a non-fast internet. Some package can choose to download from ST or Github (that work fine).  However, a lot of package do not have choice of Github.TIA

Hi,I'm using CubeMX 6.11.0 (STM32L4 package version 1.18.0) to generate code for the STM32L412 with LL drivers.My configuration enables the VREFINT and TEMP channels for ADC1.The generated function MX_ADC1_Init() contains the line  LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_CHANNEL_VREFINT|LL_ADC_CHANNEL_TEMPSENSOR);  which should actually be  LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_VREFINT | LL_ADC_PATH_INTERNAL_TEMPSENSOR);  This prevents correct temperature channel measurements.

Hello, I would like to knowto know, for the ULN2804A, if the logic gates invert or not.If so, is there an equivalence without inverting gates?

 Hello, I'm new to working with STM32 microcontrollers and coding in C. I'm trying to send data in hexadecimal format using the FDCAN bus. However, when I check my code during debugging, I notice that the transmitted data looks different from what I expected. The same thing seems to happen with the received data. Can you offer any advice or help on how to fix this?

I am used to find the CMSIS files (especially stm32f10x.h) in the same ZIP file as the STM32F10x standard peripheral library.In my legacy project, someone used the SPL V2.0.1 together with a stm32f10x.h V3.1.0.Unfortunately, the code won't compile under certain circumstances due to symbol overlap, namely duplicate definitions of types (like u32) defined in both stm32f10x.h and stm32f10x_type.h files. My interpretation is that someone has used an incompatible CMSIS and SPL version.I have checked the SPL V2.0.1 archive and it does not contain CMSIS at all. Nevertheless, I assume that CMSIS already existed in SPL V2.0.1 times.My question: Which CMSIS version is compatible with SPL V2.0.1? Where can I get this CMSIS package?

HelloI am a STM32CubeIDE user. After installing STM32CubeIDE for the first time, run it to create a project, you will be prompted to connect to the Internet to download the package as shown in the picture below.However, I need to participate in the competition with STM32CubeIDE, but I cannot use the Internet due to competition rules. So, you need to get the installation file of STM32CubeIDE to USB and download it. Is there any way to avoid the error in the picture below and download the package and STM32CubeIDE without internet??

Hello all,We're having some 'strange behaviour' when interfacing our STM32F7 to a FPGA over the FMC bus.  To isolate the problems, we're looking at all the control/addr/data on the FMC bus during memory transactions.  We have a very good view into everything via the Lattice Reveal tool.   The FPGA has 16-bit data bus, and we only want to access one register/memory location at a time.  Even though we disabled data cache, we see multiple reads (separate NEx chip select assertions)We are not using the MPU (yet)We configured the FMC for 16-bit access, so it would ignore the upper halfword of the data bus.  We figured if we read only 16-bits, it would just do one read cycle (NEx assertion, OE assertion).  We see the memory controller trying to read address 0x00 and 0x01 in on read cycle, obviously 32-bits.   Our assembly code clearly shows ldrh (load data register half-word). Any insight welcome.  If you want us to post more detail

Hi all!  I'm looking for a custom numerical keypad, with negative sign, comma(for float vaues) , clear and enter.How can i create? I found only querty, and numerical without comma and sign. Thank you! 

Hi STM32-Community,I'm currently using an STM32L4R-MCU and was trying to set it up for standby. By using LoRa, I don't want it to keep requesting an OTAA-Command to join the network, I'm trying to use the SRAM2 Retention of my MCU in Standby-Mode. Googling and skimming through the datasheet, I only found at which adress the 64 KB SRAM are located, but how do I actually write to that memory and also read it back again?I've neither found an application note, nor an example code. I would be really glad, if someone knows more about this topic.Kind regardscrackl1ng
