Check data availability at Serial port

[nikhil]

Hello,

I am using STM32F4 MCU and Serial driver using ChibiOS. I would like to know if there is any way to check for serial data available at serial port. I am looking for something like Serial.available() feature in arduino.

Hi,

If you try to read with TIME_IMMEDIATE then you can know that because the call becomes non-blocking.
