how to check UART Data buffer?

[rashisdk]

in C we can use this command to check Data in UART receive buffer is ready for reading,
" if (UART1 Data Ready () ==1 "
but how we can do this in flowcode??

Hello,

in C we can use this command to check Data in UART receive buffer is ready for reading,

I'm guessing this is from Arduino C.

The easiest way is to use a RX interrupt to put the data bytes into a circular buffer as it comes in. You can then poll the buffer as part of your main program. This way you get far more data buffering then the UART hardware can provide.

Here's an example.
