Hello,

Thank you for your question!

If wanting to send characters (rather than integers), please see sci_ex2_interrupts.c in C2000Ware (in C2000Ware_version_num\driverlib\f28004x\examples\sci). This example provides use of characters rather than hex/integer transmission.

To simplify, in C, all that is required is to enclose the character(s) being sent in quote marks e.g. n= "234\0" (NOTE: the line-ending character \0 is needed for the line to actually print on the receiving terminal), then transmit using one of the driverlib functions e.g. SCI_writeCharArray(SCIA_BASE, (uint16_t*)msg, 4); (NOTE: 4 characters sent as the line-ending character is included as a character).

Please let me know if sci_ex2_interrupts.c was useful in bringing clarity to the question!

Regards,

Vince

If you want to send an integer as string, use sprintf().

char buf[8];

int n = 234;

sprintf(buf, "%d", n);

If sprintf() is too heavyweight for you, you can use the itoa() example from K&R.
