Hello , I have STM32H750x MCU. I would like to know why the ETH DMAMR->SWR (software reset bit) is still ALWAYS SET?I know even the HAL driver is trying to do the SW reset on the ETH DMA and MAC. I know I should have an enabled and stable clock for t...
In the example while(HAL_I2C_Master_Transmit_DMA(&I2cHandle, (uint16_t)I2C_ADDRESS, (uint8_t*)aTxBuffer, TXBUFFERSIZE)!= HAL_OK) { /* Error_Handler() function is called when Timeout error occurs. When Acknowledge failure occurs (Slave d...
hello everyone, I am trying to generate a square wave at a desired frequency. I am supposed to use the TIM3 peripheral. I selected the "Output compare CH1" for channel 1 section and under this section it asks me for a pulse value (which I know is th...
If the H7 HAL_SPI driver function HAL_SPI_TransmitReceive(......) is called in my main(),It runs correctly, I can transmit and receive data correctly. But it is called in my EXTI9_5_IRQHandler() interrupt , It runs dead loop, and can't return.
hi dear.I have some problems with the Flash bank configure.STM32F767 is used by setting Flash Bank to Single or Dual.So I want to set Dual Bank Mode on Flash Memory.However, the Dual Bank setting does not work properly. I changed the Option byt...
Hello all,I have STM32F439 MCU.I use STM32CubeProgrammer to program the MCU through ST Bootloader.STM32CubeProgrammer writes:Bootloader protocol version: 3.1According to AN2606 (STM32 microcontroller system memory boot mode) the valid version for ST...
HiI'm using a Nucleo-144 with a STM32F767ZI.I have included in my project FreeRTOS and FreeRTOS-IP although that may not be related with the problem, since the crash happens before reaching the initialisation of FreeRTOS.My problem seems to be that H...
Ok, I scratched my head long enough and now my hope lies with the ST Community. =) I would like to understand how this code in the header file stm32f1xx_ll_gpio.h works. In particular, what does (Pin >> 24) do? I suspect that the code sets two regist...
Hello , I had started a project with STM32F410RB wish communicate with a keyboard and LCDActually i wrote my program that call SysTick_Handler from stm32f4xx_it.c to interact keyboard and detect if there is a button pressed and wrote caracter on LCD....
can we achive USB 2.0 on STM32L152RCT64SF without oscillator?
