LP-MSP430FR2476: printing two digit integers in teraterm

Hi,

I added uart print functions from 

Lesson 9: UART – Simply Embedded

uart_putchar(RXData[3]+'0');

This works to print single digit numbers as char. Two digit integers are printing blank. How to fix this?

Thanks,

Priya

    You need to create a string using something like itoa() from K&R.

    If you *only* want two digit integers you can do something like:

    int i = 42;

    // print MSD

    char msd = (i/10) + '0';

    uart_putchar(msd);

    // print LSD

    char lsd = (i % 10) + '0';

    uart_putchar(lsd)
