RTOS/MSP432P401R: Partial return enable in TI RTOS

Kavan Acharya
Intellectual 685 points

Part Number: MSP432P401R

Tool/software: TI-RTOS

Hello ,

Iam Working on MSP432P401R launchpad.

Iam using TI RTOS

I have configured UART in read callback mode

with baud 9600

I have set the receive buffer size as 10 bytes. When I send any data read call back will not be called untill I send 10 bytes

But My requirement is as soon as I send any data less than 10 bytes call back function should be called.This can happen if I enable partial return using UART_control API.But I don tknow what arguments to pass to this function

    Hi Kavan,

    From the documentation, partial returm is not available for the MSP432. You can find the documentation for the UART driver here:

    Here is the info for the UART_control commands:

    Your best option would be to read 1 byte at a time and have an internal counter to see how many bytes are received. You can also add a timer or clock to check for timeouts.

    Regards,

    Michel

    Hi Kevan,

    Which version of TI-RTOS are you using? In TIRTOS 2.20.00.06, if you use read callback mode, the read callback function should be called whenever the receive buffer is full when readReturnMode=UART_RETURN_FULL or whenever a newline character is received if readReturnMode=UART_RETURN_NEWLINE (when driver is in UART_DATA_TEXT mode).

    Best regards,
    Vincent
