Hi all,I am using UART4 in STM32F205 connected to an external device with an RS485-Transceiver (sn65hvd75).When I transmit data (HAL_UART_Transmit_IT) I set the TXEN pin high in RS485-Transceiver and when I get a callback using HAL_UART_TxCpltCallba...

Hi How Do I get the cpu utilisation in stm32?I am using STM32F205 with platformIO Ide.I dont want to use Task list view in freertos as it is intended for debugging only.Any help would be much appreciated.Thanks

Hi,I am using STM32F205 Board for our development. We were using HSI (16MHZ) as the clock and found out that HSI has issues with high temperatures. I am calibrating HSITRIM value to fix the clock drift issue and we already have 50 boards manufactured...

Hi ,I am using an STM32F205 for my project. We were using HSI as the clock source before and found out that HSI will not work very well with high temperatures for UARTs, So we added an External crystal clock (16Mhz) but I am unable to get Comms out o...

Hi,I am Using an stm32f205 on our board. All the Uarts works fine at room temperature. But when the temp increases above 58 degress, messages started get missed in the uarts or sometimes it completely stops sending messages.I am running the board at ...

@mbrossett Thanks for the response. That fixed issue, xEventGroupWaitBits had a delay

@TDK Most of the messages sent by the external devices are getting corrupted. Here is how we transmit and receive messagesTransmit Functionvoid UART::tx(const uint8_t* to_send, size_t length) { //Set TXEN pin High if (_txen.has_value()) ...

@TDK Thanks for the replyI use the HAL_UART_TxCpltCallback to set the TXEN low. I used the scope and it seems like TXEN held high little bit longer even after the transmit is finished and recieve msgs are not getting through.

Hi @STTwo-32 ,Thanks for the reply,The issue that I'm currently facing when I try to configure HSE, the board which doesn't have an external Crystal crashes .The system Crashes here when I configure RCC_OscConfig if (HAL_RCC_OscConfig(&RCC_OscInitStr...

So Once I configure the the clock with HSE, wait for HSERDY bit to set (How long do we need to wait?), if not set then reconfigure clock with HSI?
