One big differences I find between traditional ASM code and C in dealing with decoders, is in the beginning, IR commands are #defined as constants, and the incoming command is XOR'ed with the constant ...

re: which program ?
The simple one that ONLY tests the 2 I/O pins at a 2Hz toggle rate.

It is possible that either there's a basic hardware problem (wrong pin, solder whisker,wrong resistor value) ...

They only do what the program says to do....
You need to post your simple test program.

Which Program? I’ve already posted the code and posted a video of the prototype! One can compile the code ...

Both shouldn’t blink like this, they should be steady on and off with each button depress and release.

Here is a video of the test setup.

This is my test setup.

easy...
cut SIMPLE code to toggle those pins at say 2 hz( 2 seconds on, 2 seconds off),use 4k7 as the 'loads', now check with scope or DVM.
if that doesn't work, post THAT program...

At the momen ...

I have some code I’m working with for a Volume and relay control. It’s working as intended except for one thing. The momentary action of pins A0 and A1 only output less than a 1VDC, they mimic th ...

You do realise that this is code to _receive_ the NEC protocol, not to generate
it.

My apologies, I should have posted under a new thread.

I finally found some code that I could use for the 12F1822, using the NEC protocol, Ive been studying alot of assembly code, and seem to have a better grasp on it, I would like to learn more C, but at ...

How would this switch statement look in CCS C? Thanks

// key1 0x50 to Toggle relay 1 // these are command of the IR remote control which i have
// key2 0xD8 to Toggle relay 2
// key3 ...

Just from reading the original code, there is nothing written in the code that tells the chip what to do when there are no commands coming from the IR sensor. From code we don’t know the state of th ...

You can probably 'mask' them.
'Masking' allows you to select or eliminate bits from bytes using logical AND and OR as required.
There may be info in the FAQ section of the manual, check some of the ...
