Hi anybody in this forum please kindly help me to resolve the following problem: When I run the debugger (simCASE debugger) , each time when it reaches the printf commands, it stops completely. I want to simulate the code using Serial window to display say .. printf("HELLO "); Please help,either drop me an e-mail or post you reply at this forum. My e-mail is: jsayavong@perkinselectronics.com Thanks in advance
"The source of the original printf()/putchar() is probably in the library directory" The C51 Library folder contains the putchar() source (putchar.c, I think). You don't need to fiddle with printf(), but note that printf() is a very large function - there isn't much room left with the demo versions once you've used printf()!! :-0
