No longer a CCS problem so they prob won't want the other problem talked about here. I can tell you I just checked and ICD2 debug works on my 18F25K20 which is pretty much the same chip as yours. I'm ...

OK, firstly for anyone who hasn't used a 'K' series PIC, he is talking about a zener on MCLR because the 'K' series require <9V on MCLR during programming.

Now, Pin B3 is not the default pin fo ...

Another alternative is to use write_bank() command and force the starting address of the array using #byte to begin at the start of a ram bank.

Not as good in your case obviously, but this retains ...

forgot to log on :/

thanks guys

I take it the 18F CCS compiler is just as reliable for the (newer I think..) 18FxxJ series as other 18F parts?

OK problem solved by doing the register bits myself... heres the change in case anyone comes searching down the track...

I replaced this line from the above code:

setup_ccp1(CCP_PWM | CCP_SH ...

Hi guys, I'm trying to use the PWM feature on pic16f690 where the comparator module can be configured as feedback to shutdown the PWM.

Here is my test code...
-LED toggles as I change the voltage ...

thanks very much guys, thanks for the example PCM programmer thats exactly the type of thing i was hoping to do.

Just thought i'd add why i'm doing this. My project is a basic IrDA protocol stack microcontroller. So its an infrared connectivity solution that any micrcontroller can communi ...

lol i found the problem, in getIrdaByte() u'll see i don't initialise ch to 0. Strangely the ch initialised as 0b00001000 when using the interupt method, but initialised as 0b00000000 when using the p ...

Thanks for that

I've spent another few hours on it, polling routine works all the way up to 200+ instruction delay, as i'd expect.

Now in disbelief that my code could possibly be giving me this ...

no ideas?

Tommorow i'll to set up my detected() function to delay the same i'd expect from the interupt, this is around 20-25 instructions right?

timer1 is on a div by 8, so 104us calculates to 36 increments of timer1 i think it was. But i've tried increments around 36 to see the effect (which is why it was at 32 when i posted the c ...

Well all has been going well up untill now, i am having problems now that i'm trying to use an interupt.

I'll explain what i'm doing first:

-I am receiving infrared data. It is IrDA encoded ('1 ...

Thanks heaps! LEDs are flashing Very Happy

it says 2 - 5.5 voltage range, i'll be using 3V, but i have tried at 5V too
