I'm trying to get ADC values from multiple channels of ADC1 of STM32F103C8T6 using DMA where conversion is triggered by TIM3 every 1ms. However, I'm not seeing the right values. I tried the polling mode and that worked fine. Here is the main function code so far and the settings in CubeMX. The full code is here. What am I missing? int main(void) { /* USER CODE BEGIN 1 */   /* USER CODE END 1 */   /* MCU Configuration--------------------------------------------------------*/   /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init();   /* USER CODE BEGIN Init */   /* USER CODE END Init */   /* Configure the system clock */ SystemClock_Config();   /* USER CODE BEGIN SysInit */   /* USER CODE END SysInit */   /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_ADC1_Init(); MX_SPI1_Init(); MX_TIM1_Init(); MX_I2C1_Init(); MX_USART1_UART_Init(); MX_DMA_Init(); MX_TIM2_Init(); MX_TI

Hello allI use ST25DV64K.​If I2C communication is used to access EEPROM while APP is writing to EEPROM, it will cause an error on APP side.Therefore, I would like to check the status of the NFC tag when it is being written from APP.And while writing from APP I want not to access by I2C communication, how can I do this?Is it possible to find out by reading a register somewhere?I thought one of the "IT_STS_Dyn" would be set to "1" while writing the EEPROM of the NFC tag from APP, but they all stayed at "0".​BRMorooka​

How can I configure a Run configuration for flashing that doesn't also break and throw me into the debugger? Note how all the relevant options in my Run configuration are greyed out. How can I enable them?

I am using STM32H750 MCU . I configured 14 GPIO as interrupt and handle in HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) function. In few GPIO pin number is same and different port .(PA6 , PI6 and PJ6).How to find proper interrupt PIN?

I've run into another hurdle I don't seem to be able to solve myself while trying to learn embedded STM32 programming. I have a simple test program that transmits characters over a UART with the RX and TX pins looped together and receives them using interrupts. When I transmit the data using HAL_UART_Transmit, I can process the received characters in my IRQHandler fine. But when I use HAL_UART_Transmit_IT, my IRQHandler puts 2 characters in my receive buffer for every character I transmit. I'm pretty sure this is because my IRQHandler is getting called for every character transmitted and every character received. You can see how I tried to only process received characters in my IRQHandler below but it hangs up after a few characters. Any ideas on what I'm doing wrong or any ideas on a better way to do this will be greatly appreciated.ThanksPS In the long run, I'd like to make this work with DMA and end the transfer using the character match interrupt. I've got that working on a STM32H7

Hi Everyone!We have two RFM98PW LoRa Modules and we successfully can communicate with these modules from more than 9 kilometers. But when we change our frequency from 434 to about 433.663 we cannot communicate very well. It just *****. Using these LoRa modules with an Atmega2560 and STM32F446RET6. In Atmega, so in library that we are using setFrequency function to change frequency. Is it enough to change freq with just a function. Do we need to change anything else like bandwidth?When we change the frequency the frequency error jumps to 32 kHz from 1 kHz in the receiver serial port.Library: https://github.com/SMotlaq/LoRaThanks.

HiWe have a board with STM32F769BIT6 MCU. When we drive the board with 3.3V, MCU current consumption is about 400~450 mA and it gets really hot!When we drive the board with voltages below 3V, for example 2.5V, it takes about 20~30 mA and stays cool and fully functional.In the datasheet it is stated that the operating voltage range is 1.8 to 3.6. We have designed our board based on 3.3V but this high current consumption and high temperature is not accepted for us.Our design is completely based on STM32F769I-EVAL. Only the package is different. We are using STM32769BI (LQFP208) whereas the evaluation board is using STM32F769NI (TFBGA216). We have declared all IO pins as analog inputs so as to avoid accidental current draining.Does anyone have similar experience? Are we missing any point here?Thanks in advance

I designed my robot control system using STM32MP157f-K2 board I use the M4 core to read an IMU through SPI, read encoders and generate PWM for controlling the motors by using timers. I use A7 to read USB vision cameras, read a radar by using CAN bus, and read a lidar using ethernet. After processing the data, it sends the results to M4 for fusing with encoder and gyrometer data to make better control decisions.I have the M4 firmware created using STM32CubeMx, and a A7 application compiled in linux. I expect them to communicate one way from A7 to M4 through virtul_uart0. I haven't been able to test the codes since I don't know how to start the Me firmware, When I loaded it directly from STM32CubeMx, I got into problems I had to reflush the board. My questions are two, and I will appreciate any advice(1) How can I open the Linux shell on the on-board LCD screen instead of mapping it to my computer using STLink(2) How can I start both the A7 application and M4 firmware automatically and d

Hi Experts,Has anybody tried configuring the ST25R3916 in Card Emulation mode using external MCU using SPI bus ? I was looking for what register/s need/s modifications ?Thank you for the help in advance.regards.

I'm trying to send and receive Unstructured Vendor Defined Messages with the ST USB-PD stack but there is very little information in the documentation about the API.I have found that I need to call USBPD_PE_UVDM_RequestMessage after which the stack will fire the USBPD_VDM_SendUVDM callback. However, the stack usually calls this function more than once, and it's not clear how to send more than 1 VDO.Am I supposed to copy all of the data to the address given by pVDO or only copy 1 VDO each time the function is called? What is the maximum number of VDOs that I can send? Why does the stack call this function more than once when I can see on a PD traffic analyzer that only 1 message is sent over the wire?Is there some document or example that actually explains how to use UVDMs? It seems like VDMs are mostly just used to enable DisplayPort support. I need to send small arbitrary messages between several boards connected with USB-PD.@Yohann M.​ I stripped out the function params on the i

Hello community, how are u?Hope everyone is well and safe =)I'm developing an application using SBSFU. While testing the examples (withoout provisioning a AESKEY, only flashing SBSFU engine) i could always return my microcontroller to factory, just changing the RDP option byte in STM32CubeProgrammer. After doing that, all code of my microcontroller was erased and i was able to use it normally again.My problems began when i provisioned AES KEY to CM0 CPU.To return to factory, i tried to do the same procedure i described above, but when i try to flash a new firmware i keep receiving a message from IDE that "Flash erase was not possible in sector 1-79", even though i'm able to erase and read the flash using STM32CubeProgrammer. All my write protections, read protection and PCROP are disabled. I'm not able to flash a firmware using STM32CubeProgrammer aswell, i get a message of "Flash download error".Previously the AESKey provisioning i was able to factory reset, now i'm not and to make ma

Can there be a 2d barcode reader app or program on your computer or phone?

Hi all,I am trying to achieve DDR data transfer between M4 and A7.So I followed How to exchange data buffers with the coprocessor - stm32mpu article and built a yocto image. I have stripped down the logic analyzer application : here . On CM4 side it just transfers data from a another MCU pushing in data at UART7 and transferring that via DMA to DDR buffer. SDB Driver unchanged.On the Application side , I have removed all GTK related things and just stripped it down to receive data to DDR buffer and print to a console.I have few questions of concerns: In case of the CM4 code provided here : LinkThere no support in the latest cube-mx to create an RPMSG_HDR_HandleTypeDef type object which might be labelled as /dev/tpmsg-sdb type in user space application.Although the data structure is similar to VIRT_UART_HandleTypeDef. So I went ahead and made and rpmsg-sdb object of the later type. Now when I run my stripped down application part of attached zip. I get below error on A7-console : CA7 :

Hello,I am using the FIFO to read the gyroscope and accelerometer data from the LSM6DS33 using a Raspberry Pi. It is connected over I2C at a frequency of 400kHz. Currently it takes between 4-7 seconds of constant reading to empty out the FIFO and by then it's almost full again. Is there a way to do a bulk read of the FIFO rather than read each sensor reading separately?Thanks,Mahmoud

Hi,The package UFQFPN32 (5x5 mm) have an exposed pad but where is the definition of this Exposed Pad in the datasheet for the STM32F302K8 K Must I connect to the GND or is it not connected or maybe another pin definition ? I can't see in the datasheet.Thanks for your help.

I'm using USART2 on PB3 and PB4 which means setting the AFR bits for those GPIO pins to 7. The CubeMX wizard and HAL GPIO libraries agree with this, but the AFR bits for PB4 stubbornly revert to 0 and my USART wont transmit. What is going on? I've tried my own code and the behaveiour doesn't seem any different. Using a data access breakpoint I can catch the expected writes and in the debugger I can set the AFR momentarily, but then it reverts. The lock register reads zero.Is it a hardware issue?

Hi,I have a new project with STM32G474CE and cant get it start. If I program it with STM32CubeProgrammer it runs the a simple code for led blinking. I checked all VDD,Vref,Vbat pins and all okay. But after powering it off and on again, code gets stuck.I debug it with keil and see it is stuck in some loop at the beginning. Same thing happens if I programm it with keil, it cant reach to led blinking.I checked the option bits with STM32CubeProgrammer for boot0 and it is unchecked.

In CubeIDE SFR view systick registers names do not match Programming Manual definitions.SFR:register | addressSTCSR  | 0xE000E010STRVR  | 0xE000E014STCVR  | 0xE000E018STCR   | 0xE000E01Cpm0214, page 246:register | addressSTK_CTRL | 0xE000E010STK_LOAD | 0xE000E014STK_VAL | 0xE000E018STK_CALIB | 0xE000E01CSo which register definition is correct?

Hello ST Community,in my application I use an STSPIN32F0B in FOC.The design is similar to the STEVAL-SPIN3202 demo board. I used the STSPIN32F0A in Motor Control Workbench to generate the code (STSPIN32F0B is not in the Motor Control Workbench). I use it to control a BLDC motor sensorless. PWM frequency is 20kHz and the deadtime 900ns. The control of the motor works fine.the only thing that strikes me as strange is the oscillogram of the 3 phases. Here there are sporadic short intermediate pulses between the 20KHz pulses (see oscillogram)Do you have any idea what is happening here?Thank you very muchBest regardsFranz
