Hi everyone!I see unexpected values when measuring VREFINT. The ADC measures around 1.18V, on some boards even 1.16V, which is outside the tolerance according to the datasheet: Reading the calibration value VREFIN_CAL from OTP memory returns a value of 0x5E29 (1,214V). Considering my ambient temperature of ~25°C, I would not expect the measured value to differ too much from VREFINT_CAL.I then used VREFIN_CAL to calculate VREF+ according to section 29.4.35 in RM0436:With the ADC-measurement of VINTREF, this calculates to VREF+= 2.57V. The actual voltage (measured with a multimeter) is 2.502V.All the other ADC channels are pretty accurate.My DeviceTree setup for ADC2:adc2:adc@100{ st,adc-channels = <12 13 14>; st,min-sample-time-nsecs = <50000>; assigned-resolution-bits = <16>; status = "okay"; channel@12 { reg = <12>; label = "vsense"; status = "okay"; }; channel@13 { reg = <13>; label = "vrefint"; status = "okay"; }; channel@14 {

I bought Nucleo-L4R5ZI.​I can't find any document with HW information such as memory map, registers, etc. for Nucleo-L4R5ZI.I could find a document with HW layout and other information.​Where can I find a document that contains HW information such as memory maps, registers, etc. for Nucleo-L4R5ZI?

Iam new to stm32 microcontrollers, i have to read uart continuously and store to array. and size of the data received from uart is variable. if i use the fifo with uart i can solve problem.so please help me how program to receive data from uart in fifo

I want to implement a system so that it retrieves sound by mems microphones and classify it with convolutional neural network. I have spent a lot of times to use BSP Library in my project but I failed. Therefore, I decided to use the code provided in f7cube file in the repository to retrieve sound. Furthermore, I'd like to use xcubeai with this code. To do that, I have to add CRC configuration, however, it throws an error as in the title. Actually I think this is about linker issue because when I add stm32f7xx_hal_crc.c file to the project, and when I apply ctrl+left click to HAL_CRC_Init in main.c file, it takes me to definition, but cubeide somehow cannot recognize it. How to solve this issue?

The reference manual (RM0440 Rev 7) has a point about WRP on page 125 regarding if the two banks are swapped. Why do the WRP2A_STRT and WRP2A_END registers have two different sets of values? It looks like one set is for Single Bank mode and the other set is what you would find in Dual bank mode, but the order doesn't match the above and there are no notes to describe why the same register has two different numbers for the same protection area. It is really unclear what is meant by this.

I'm working with STM32WL and trying to be able to generate PWM signal after wake up from STOP2 to control RGB LED. Before going to STOP2 I deinitialize PWM channel pin and disable timer clock. MCU wakes up on button press. After wake up timer clock is beeing enabled and channel pin is reinitialized. Despite that the LED is off. What else should I do to make it work or what I've done wrong? /* USER CODE BEGIN 2 */   GPIO_InitTypeDef GPIO_InitStruct = {0};   /* Green LED on */ HAL_TIMEx_PWMN_Start(&htim16, TIM_CHANNEL_1); __HAL_TIM_SET_COMPARE(&htim16, TIM_CHANNEL_1, 1000);   HAL_Delay(500);   /* DeInit of LED pin, disable TIM16 clock */ HAL_TIMEx_PWMN_Stop(&htim16, TIM_CHANNEL_1); HAL_GPIO_DeInit(LED_G_CH_GPIO_Port, LED_G_CH_Pin); __HAL_RCC_TIM16_CLK_DISABLE();   /* Enter STOP2 */ HAL_SuspendTick(); HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI);   /* Wake up from STOP2 on button press */ SystemClock_Config(); HAL_ResumeTick(); &nbsp

I'am using Cubeprog version 2.10.0 and kit b_u585i_iot02a. Flashing to NOR flash with external loader is OK and verification is also OK. Then I tried to check flash against file but it fails, too big file...Can this be fixed ? This is very useful feature when using other flashing tools and checking if flashing was successful.---------------15:02:34 : Memory Programming ...15:02:34 : Opening and parsing file: 2_2M.bin15:02:34 :  File         : 2_2M.bin15:02:34 :  Size         : 2.22 MB 15:02:34 :  Address      : 0x70000000 15:02:34 : Erasing memory corresponding to segment 0:15:02:34 : Erasing external memory sectors [0 35]15:02:42 : Download in Progress:15:02:48 : File download complete15:02:48 : Time elapsed during download operation: 00:00:13.32215:02:48 : Verifying ...15:02:48 : Read progress:15:02:54 : Download verified successfully 1

You're doing a great job.During the CR95HF reader test,The NTGA215 Tag is implemented as memory read/write. We proceeded by referring to the data sheet (61 page - ISO14443-A).Memory Read works normally, but the Memory Write function is not working properly.I'd appreciate it if you could tell me where it went wrong​[Ardiuno Test Log] 

Hello, we are developing related products using CR95HF reader.I am looking for NFC Card product with ST25TN01K-AFH5 chip for test purpose.I'm looking for a product in the form of an NFC card, not an IC chip.I'd appreciate it if you could recommend it.* This is ISO 14443A.Thank you.

I need giga ethernet working on linux.Is it possible with the STM32MP?Please let me know if you have any test results with iperf.Thank you for answers.

Please any one done this project please give me.I am trying too many times.

Ok, I'm at a complete loss here so I'm looking for any ideas or suggestions. We have a code base that runs on top of FreeRTOS and we have versions of the code that run on multiple, different STM32L4s and on the STM32H753. I ported the code base to the G0 and just started to run into weird HardFaults. Hard Faults that don't make any sense. Walking back up the stack looks completely normal. Random, what looks like, memory corruption, but it doesn't make any sense. I've run a lot of tests and an absurd amount of diagnostic code... but what I'm posting about here you shouldn't have to know any of that, because it seems like strange compiler errors.If I execute the following code, the system currently crashes (if I move things around in unrelated parts of flash/ram, then this code will suddenly start to work without issue).std::string StringOp::sizeToString(size_t sz) { std::string sout(""); do { //__asm volatile("NOP"); char digit = (char)(sz % 10) + '0'; sout = digit + sout; sz

When I create a new project in STM32CubeIDE with the use of a configuration (.ioc) file, configure peripherals, and generate code, all handlers (such as I2C_HandleTypeDef, UART_HandleTypeDef, QSPI_HandleTypeDef, DMA_HandleTypeDef, etc.) and their initialization functions are placed in main.c file.Is there a way to automatically split the code into multiple pairs of headers and source files (let's say, a header-source pair for UART, a header-source pair for I2C, etc.)?I would like to define some custom parameters and functions related to my peripherals. Of course, I can create additional headers and source files. I would just prefer to group them all together without producing multiple files.Thank you.

(On Nucleo L073RZ devkit with target on SWD) I can easily connect and program a hex file from the stm32 link utility UI but it seems impossible from the CLI. Connection parameters are the same (Mode: Normal, Reset Mode: Software system reset) and the .\ST-LINK_CLI.exe -c SWDcommand works fine, but not .\ST-LINK_CLI.exe -P C:\LoRaWAN-S76S-US915-V1-6-5.hex 0x08000000 -VBoth outputs are in the following picture.

I am trying to spin a 48V motor with an EVSPIN32G4 with standard settings. The only thing I changed was increase the startup current to about 18 Amp and adjust my motor parameters.The high frequency plot shows that the measured currents I_A and I_B reach OPAMP saturation, which is not the case because I measure the OPAMP V_OUT voltages simultaneously with an oscilloscope and the output voltage is barely moving except for the rampup alignment current that is programmed.Another strange thing is that only Phase B OPAMP has the correct voltage of 1,65V when no current is flowing, the other two outputs have 0 V.It would be awesome if someone has a clue on what I am doing wrong. Thanks!

Hi,I'm looking to port an application using the LwIP stack and X-CUBE-CELLULAR to NETXDUO. The goal is eventually create an application that connects to Azure IoT Hub over cellular.Are there any recommendations from ST on integrating NETXDUO with X-CUBE-CELLULAR or porting an example from X-CUBE-CELLULAR to use NETXDUO?Thanks,

Hi, I'd like to know if it is possible to add external libraries on STM32CubeIDE and if yes, how.In particular, I'd like to use cryptographic functions on my NUCLEO-H753ZI. And I found a library on the web I could use in the form of an archive file (.a) + a header file. How can I integrate this archive in my project so I can use the functions of the library ?Thank you in advance for your answer.

Also there is one pin that is connected to potentiometer.but there is no any options in st workbench to varry the speed using potentiometer. I look forward to hearing from you as soon as possible.thank you

I have an app with a pretty simple non blocking state machine that works pretty well. There are a bunch of UART and I2C devices along with a couple of timers that all have ISRs. When an ISR gets called, it puts its data along with an identifier and a timestamp in a FIFO queue. The main state machine processing loop gets any data in any FIFO, does a bunch of calculations, sends commands to various other devices and then does a HAL_Delay(***) for 10 to 1000 milliseconds depending on what state it's in and goes through the cycle again. Power consumption is important, so instead of HAL_Delay I'd like to drop into a low power state and wait for the next interrupt to fire, handle the interrupt and then wake up the main state machine processing loop. In order to do that, I think I need to fire another interrupt from any ISR that needs to wake up the main state machine processing loop. I would also like to post a message somewhere that tells the main state machine processing loop what ISR gene

There is a'ifdef CONFIG_SPL_BUILD' in stm32mp1.h, Makefile or many files, but there is no setting in the Kconfig file.

From user manual, from OTP word 59th for user to store sensitive information, meaning there is a way to prevent read them by STM32cube tool for non-secure application.We see the way to lock them which mean can't not change values, any document that tell how to hide these registers from STM32cube tool for non-secure application.
