In Flowcode - include the Timer component - and then can get milliseconds (etc) from when it is started.

Just using the UART decoder at present. Just checking if sigrok will do the trick...

While I was typing - Iain popped in with a test of the DMX component too. I don't have a way to test if it is a valid DMX signal - how doing?

Whilst waiting for a 16F18877 to arrive in the post - I tried a different MCU. So with a PIC16F887 (which is rather a lower specced beast) - I got a simple DMX output running (I think) Here outputting 24 channels (set to 0..23) My logic analyser reads the 'start' pulse as 0. I'm using '0' as the con...

Is this it?

The CAL (included code (Chip Abstraction Layer?)) and components might differ somewhat between the two versions. Although in increase in total program size seems quite a lot? 96% doesn't allow much leeway ! By looking at code using each of components you are using in isolation - it might be possible...

:-( How did you do the 'heartbeat' pulse - with an interrupt or in the main loop. If the UART isn't quite initialised correctly then the wait for transmission to finish - may never return. I did get output with the FC component - but that was with a PIC32 and checking the output on the oscilloscope ...

I suggest the esp32_p4! I've just received one of these bad boys.. Flowcode up and running in a matter of minutes - idf.py set-target esp32p4 Then recompile and 'Hello world' is go.... Pushing that 360MHz CPU to its limits! It has quite a few 'extras' - dedicated display and camera port (Raspberry P...

Sadly, and the most likely outcome for a first attempt - still one step forward.... I didn't add any OSCON settings - though seemed to be set at 32MHz internal oscillator - so assumed it didn't need this. Good to check though - no clock, nothing happens....

I don't have the same chip to test on - but I pulled an example from the web and coerced it into Flowcode. Perhaps you could try this - I've set it to out on Pin C0 (and for speed it is hardcoded to this - sorry) If it outputs anything - we could perhaps look at changing this if needed! I've set it ...
