I2C is sending only n-1 bytes
Hello,I'm using a F301K6T6 based board. When communicating over I2C the first RX/TX works fine but the second TX is starting with the second byte and thus sending only n-1 bytes.While debugging recognized that `HAL_I2C_Slave_Transmit_IT()` is setting...
Parallel transmission using GPIO and DMA (like AN4666)
Hi,I would like to send parallel byte data from STM32H743 using DMA, e. g. using Port G0...G7, using a timer to define the cycling (e. g. TIM3.CH2).For STM32L and STM32F4 this is described in AN4666 I think. I did this already on STM32F4, there it se...
Resolved! FreeRTOS is not running task
Hello, I'm using FreeRTOS on STM32F746NG.I have created 4 task which run with the same priority. But when I run my code,Only StartDefaultTask running, others aren't.In debug mode, when I clicked Resume(F8), the pointer always jump to start of Start...
how to get the code in C at this address?
hello,I want to take a look into the code at this addressthank you
Resolved! Is there a way to check the MCU is in sleep mode using openocd or other linux tool?
Hello,I have a nucleo-L152RE development board.I don't have an annmeter. What would be the best way to check my microcontroller is in sleep mode? Or can it be done at all? I've installed openocd and gdb but I've barely used any of them so far, so may...
Resolved! STM32F103 Alternate Function selection for a specific pin.
Hi, I am familiar with STM32F407 from my previous works. In that 40xx family, it was easy to understand, there are AFRL and AFRH registers by which user can select the desired AF for each and every pin independently.However, now, I am working with ST...
quad SPI external flash as read write access
I'm using DISCO Board STM32F769I and want to use its quad SPI external flash as read write access.is there any reference code help in that?
Timer 2(32 bit timer) in running mode to provide timer tick at 1ms. controller - STM32F072VB timer - TIMER 2 mode - up counting mode This timer should get TIm->CNT increment at 1 ms. then what should be the prescalar??
here is settings i did..but little bit confused about prescalar valuestatic void MX_TIM2_Init(void){ /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM2_Init 0 */ TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterCon...
