Tx Buffering for fsl_lpsci_driver/fsl_uart_driver?

[lucianomoretti]

It looks like the fsl_lpsci_driver (and uart driver) component does not contain internal transmit buffers like the old Asynchronous Serial Driver did to support queueing of serial messages.

Does anyone know of a good example of how to implement a buffered serial output so that I can queue multiple messages on the serial port?

Hi Luciano Moretti,

I think you may implement the queue of serial output by RTOS, such as MsgQ of the freeRTOS. for example, you may create a task to handle the msgs from other tasks , and output the serial message one by one.

Hope that helps,

Have a great day,
Kan
