I cannot get the RS232 Rx interrupt to work.I am working with the stm3210c-eval board. I know it is no longer available; but it has a version of the processor that I wish to use and Ethernet support.I am initiating the receive via:HAL_UART_Receive_IT...

The Ethernet reset is not clearing (ETH_DMABMR_SR in DMABMR).I am having a similar issue as others but have not seen a solution in the forum.I am working with the stm3210c-eval board. I know it is no longer available; but it has a version of the proc...

I tried the following code in a STM32F107:RCC->AHBENR = RCC->AHBENR | RCC_APB2ENR_IOPBEN_Msk| RCC_APB2ENR_IOPDEN_Msk;and RCC->AHBENR = RCC->AHBENR | 0x00000008 | 0x00000020;When I display RCC->AHBENR, it always shows 0001C014.I expected to see 0x0001...

Posted on October 15, 2014 at 19:38 I'm trying to wakeup the processor after it has been put to sleep by the _wfe instruction via the RTC wakeup event. It is not working for me. There are no examples of WFE wakeup in the library projects tha...

Posted on July 31, 2014 at 23:29Hi, I just received a new prototype with a STM32F215 processor and it is set up to use the SWD interface to initially flash the unit. on the ST-Link/v2 I have connected: pins 3,5 & 10 to gnd (3 & 5 to reduce noise) pi...

SofLit, To answer my own question:f I check those 2, will that screw up my existing code?Yes, it did wipe out the fixes I had made.to HAL_UART_MspInit & HAL_ETH_MspInit.

SofLit, No i did not. I see that would be an issue for Ethernet as well.If I check those 2, will that screw up my existing code?STcubeMX does handle the assigned input pins for the STM32F107. Makes them outputs.

Saket_Om, That was the problem. Why would the STcube HAL not take of that? Is that a failure of STcubeMX?

Andrew, That was an excellent suggestion. That allowed me to prove that USART2 Rx pin was working.Thank you.

If the mode is set to GPIO_MODE_AF_PP, the HAL does not control the input pull state.The HAL_ETH_MspInit function does sometimes setGPIO_InitStruct.Pull = GPIO_NOPULLbut HAL_GPIO_Init does not bother checking GPIO_InitStruct.Pull if mode = GPIO_MODE_...
