Hi. I'm having trouble managing a USB slave on STM32L4 using interrupt. I'm able to make it work using polling, and on a previous F3 project, had polling working.From RM, NVIC section, F3 has 3 USB lines: Wakeup, LP, and HP (HP and LP are shared with...
Just discovered that ARP request messages are padded with 18 bytes of trailing zero bytes, making them 60 bytes long instead of 42 bytes. A third party device doesn't like this and fails to respond to the ARP request message. I'm using a STM32F476 ...
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 registe...
