It would be interesting to know how it works behind the scenes?

Of course, now I'm thinking 4 cores multiprocessing - if the interconnect allows easy communications between the two esp32 devices

Did you try using the 12f transmitter?

The rc5 protocol seems much less common than NEC format (all the controllers I've tested generate NEC - somewhere i have a one-for-all stick that can do it, just haven't managed to find it)

The good news maybe is that i did a NEC decoder with Jan a few ...

PIC16F1847 arrived today!

I wired one up - and to a FTDI UART converter to display the received signal... I used the internal oscillator - giving a 32MHz clock.

Modified the pin and timer interrupts - here I use RB4 as input (I used an IOC interrupt - which allows either edge - it is possible to ...

Thanks Ben,

Re-flashed the 'main' esp32 via one of it's USB ports - and then I can program the board using the main USB port connected to the (I assume) 'control' device.

Phew....

A few thoughts.....

I did a simple example - that allows macros with names 'A' to 'Z' - note that if you want to use lower case - you can either alter the call to .c - 'a' (instead of (.c - 'A')) - or convert the lower case letter to upper case.
I use a sparse array of 26 function pointers (0..25 ...

This topic seems to be a duplicate of the "macro calling" topic - at least i think the detail there would apply here...

Can you give me examples of what macro 'i', 'c' etc do - most specifically how they are called .x = i(byte, int) for example

I would suggest an array with the function pointers as above, but indexed by a character ( each macro name is a single character) - then you can do:

fn_table[FCL_CHARNAME ...

One thing I don't handle (transmit or receive) is the repeated key signal... Maybe jumping ahead slightly - let's get the basic working first!

Look forward t hearing how you get on - I just found another small remote. NEC format again

I'm still waiting on the 'receiver' PIC.

However - The transmit / decode (on Arduino) seems good.. I've made a few 'tweaks' to the decoder and I used a couple of transistors to toggle the signal pin on the transmission side.
