As per my understanding of stm32 uart driver interrupt code the usual process for receive interrupt is,1. HAL_UART_Receive_IT:It checks if huart->RxState is HAL_UART_STATE_READY.If true, it sets huart->RxState to HAL_UART_STATE_BUSY_RX.2. When Data i...

Can Single DMA channel be used for multiple DMA Streams?As per Table 43. DMA1 request mapping in reference manual, Can I use Channel 6 for Stream0 (TIM5_CH3), Stream 3(TIM5_CH4), Stream 4 (TIM5_CH2).I understand that Single stream I cannot use more t...

Thank you, Please find the UART6_ReadBuf calling code static uint8_t reset_slave(void) { uint8_t cmd = 0x0F; uint8_t ret_val = 0xFF; UART_driver_Deinit(); MX_USART6_UART_Init(9600); Start_uart_timer(200); UART6_WriteBuf(&cmd, 1); UA...

I did some further debugging and found out what is happening. This issue happens whenever there is a noise on uart line. Sequence is as follows:1. DeInit and Init UART which sets huart->RxState is HAL_UART_STATE_READY.2. Transmit data using interrupt...

Also, kindly note that I would be using all three streams simultaneously.
