Hello, I try to make an UART communication between Nucleo STM32F030RE and a STM32F030K6 mounted on a custom pcb.sends from NUCLEO to STM32F030K6 is OKReceive from STM32F030K6 is ok sends from STM32F030K6 to NUCLEO is OK (i can check it and decode thanks to oscilloscop)Receive from NUCLEO does not work (i used PA10 RX pin of UART1 of NUCLEO)Here is the code i use for NUCLEO:int data1 = 0x21 ;
int data2 = 0x22 ;
char *datachar1 = (char*)&data1 ;
char *datachar2 = (char*)&data2;
char *data = (char*)strcat(datachar1, datachar2) ;
char *msg = "KO \n\r";
char *Rxbuffer = NULL ;
int status ;
while (1)
{
HAL_UART_Transmit(&huart1, (uint8_t*)data, strlen(data), 0xFFFF);
status = HAL_UART_Receive(&huart1, (uint8_t*)Rxbuffer, 2, 65000) ;
if ( status == HAL_OK )
{
HAL_UART_Transmit(&huart2, (uint8_t*)Rxbuffer, strlen(Rxbuffer), 0xFFFF); //send to monitor the reception of uart1
} else {
HAL_UART_Transmit(&huart2, (uint8_t*)msg, strlen(msg), 0xFFFF);
}
HAL_GPIO_Tog
