Thanks, it worked great!

That's very helpful. However it was not obvious. I'm new to C programming and could not find any info on how this would work. My assumption was that printf would still be responsible for sending th ...

Hi Douglas,

Thanks for your help with this. If I could get this working is should do just what I need. However I must have made some kind of simple coding error. It all works, but the message do ...

PCM Programmer;

I forgot to include it with the post. Here it is:

#define TIMER1_PRESET (65536 - 5000) // Interrupt every 5000 counts

// t1 timer used for key switch management

Congratulations !!!

You have helped me with a couple coding issues over the past year. Your knowledge of C, the CCS compiler and the posts on the board is incredible.

Please keep up the goo ...

All,

I was wondering if I could get some input from the group. The following is a small part of some PWM code. The PWM users PWM1 and Timer 2.

PCM Programmer,

Thanks for all your help.

I would like to use either the code you recommended or Mark's code, modified (with the bug fixes) at 20 Mhz with the T1 timer.

I tested the code in ...

PCM programmer,

I am running this on a 18F252 at 4 Mhz to test. I have another card with a 18F252 at 20 Mhz as well.

I used Mark's code as per the link. The code now looks like this. I ch ...

PCM programmer,

I made the changes you recommended and it worked on the T3 or T1 time. However at 4 MHz it is slow to react to a key pressed. Mark's code at 20Mhz was much more responsive. To us ...

Hi all,

There is a block of code on the forum (Multi-Event Switch Action for Microchip Microcontrollers) that I would like to use, however the code uses Timer2 set for 1 ms ticks. In my code T2 is ...
