Hi,

I am working with LP-mspm0g3507. I want to handle multibyte data over UART with FreeRTOS. I got two example code in sdk . but that handles only single byte at time. I have done some modification but it wont work. what changes need to do in UART configuration to handle variable number of bytes.

could you give more details what you mean here?

We do have FIFO that can input multibytes in the code

I am using uart_callback_LP_MSPM0G3507_freertos_ticlang example code. That code receives single char from console and write it back on console. but with same example when I tried to send string of let say 10byte. some byte got missing.

you can refer to this code

uint8_t UART_writeBuffer(uint8_t *pData, uint8_t ui8Cnt)
{
uint8_t res;

while (ui8Cnt--) {
DL_UART_transmitDataBlocking(UART_0_INST, *pData);
pData++;
// __delay_cycles(10000);
}
}
