WebDec 6, 2012 · 8051 c interrupts. I'm using C to write a program on an 8051 microcontroller. The compiler I'm using is Keil Microvision. I'm stuck and having trouble figuring out what is missing from my code. I know it's very basic code I just can't figure out what I'm supposed to do. So pretty much what I am doing is taking sending a sentence out to the user ... WebThis function is potentially unsafe because it resets the RI bit before reading the SBUF register.
