I'm using MQX 3.5 and a M52259demo board. I having trouble simply adding another serial port (polling type) while having the existing terminal functionality on ttya. I'm an Interniche user that finds the Interniche code easier to follow.
With Interniche there are two commands: uart_putc( int unit, unsigned char ch) & uart_getc( int unit). I'm using two serial ports just fine. I'm trying to port code over to MQX and can't find a similar command.
The only commands I come across is putchar & getchar. That works for one serial port, but I want to use two serial ports. Is there a similar command like in MQX like the ones above from Interniche?
Solved! Go to Solution.
Attaching an example that can be copied and pasted into the MQX4.x/mqx/examples/io project to play with a second UART of your choice.

Hi Terry,
You need to enable the appropriate #define for the second UART you want to use in the user_config.h header file and then re-compile the build_libs.mcp for the demo board.
Then reference the enclose example. It is simple modified/enhanced version of the examples/io project.

David
