Hello friends, I'm in my last year in university and my project is about Keil Software. I have do several things... but now I have a big problem. Testing my board with 8051 all the programs work perfectly, less when I try to call a interrupt function.... It's really extrange because in the debbuger of Keil works with any problem but when I program my micro the program never takes any interrupt function. Some of you can help me? Thank you!!!
