Hi Demon, sounds like you are smart. What you are explaining makes sense. Yes, the DTMF decoder output goes to 4 ports of the 16f877. It is easy to do, If portx and portx and portx and portx=1 then...
I am using a DTMF decoder with the 16f887 chip. The decoder circuit works great which and simply runs a program, and that works great. is there a statement that can tell the e prom in the 16f887...
I am a newbee at this and have a simple program that works great. The program switches on a led at the beginning of the program, but what i need is if the led is on at the end of the program, is...
Great info, I have no analog or comparators.. What would be the best commands for everthing digital so I can test it in that mode. I always get confused with the data sheets. Thanks so much, leon
I am working with a 16f877a and everything works great with my program, but when I take porta.5=0 to run the program, it's like the mclr resets. All other ports are like this using a 5k pullup...
I have version mcs 2.43 I'm trying to fine out what version pbp is.
THE ONLY CHOICES I HAVE IS THE 16F877 IN MICROCODE STUDIO. I HAVE HAD THE PROGRAM FOR ABOUT 4 YEARS NOW. IT MIGHT BE OUT DATED BECAUSE IT DOES NOT LIST THE 877A. HOW WOULD i UPDATE?
I just started with PICbasic pro and trying to put the cmcon=7 but when I compile it, an error says (undefined symbol cmcon). I'm using the 16f877a chip.
Bodgan, that was a great link. That relay let me know about pullups and pulldowns. Thanks
ok Tenaja, I understand the internal pullups but what I realy want to know is if you were designing a circuit with switches controlling inputs, would you use
a 1 to trigger the input or a 0 to...
I want to put a row of dip switches on inputs to the pic16f877a and can either switch them to low or high to get the same result. Is it better to switch to ground with a pullup or make it go to 5v...
Hey great, this really helps me out. Good Job!!!
Melanie, you are right, it is a 876 and not a 876a. And I did not know the the 876 has been replaced by the 876a. I'm new at this and bought some 876 chips cheep. Will the 876 program still work...
for the 16f876, i need to know how to set the trisa. they give examples like trisa%11111111
but trisa only has 6 ports on the 16f876. How do I state this?
