Please Do This ...
1) Config your usart and enable RX interrupt (9600,1,1) on CubeMX.
2) Select "General peripheral Initalizion as a pair of '.c/.h' file per peripheral" on project settings.
3) Config your RFID_Config.h file.
4) Add RFID_CallBack() on usart interrupt routin.
5) Call RFID_Init().
6) Put RFID_Loop() in your main or a task.
Example:
#include "RFID.h"
.
.
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
if(huart->Instance == USART2)
{
RFID_CallBack();
}
}
.
.
int main()
{
.
.
RFID_Init();
.
