Hello Everybody, I have interfaced 8255 to 8051. 8255 do not allow to control individual bit of the port. I want to control the port bits using compiler. I was doing this with HighTech compiler but facing problems with Keil. can anybody suggest the way to do this.
"I was doing this with HighTech compiler but facing problems with Keil." What problems? "can anybody suggest the way to do this." You have, of course, read the Keil Manual, haven't you? bit-addressing is not part of the ANSI standard, so it is highly likely that different compilers will have different implementations of this extension!
I have interfaced 8255 sorry to hear that. Erik
