Thanks Ben - that explains the read of the port registers.

I still have the odd layout - with the masks as 0 (until I minimise the select pin(s) diagram)

Sorry - I'm not sure I follow - "negative edge behaves as if both edges are triggered"? Is this a limitation of the MCU (the same ISR is called for rising, falling and both - although this would usually(always?) be the case) Please can you post a code snippet that demonstrates - this and t...

Also to check that you are not trying to use a switch and just seeing 'bounce'?

I don't have that part to test with - sorry. As a simple 'thought experiment' - can you add code to set the interrupt pins as 'inputs' before the interrupt icon? (set TRISA or use read a pin using input) Set the pins to be 'digital' (set ANSELA) Add a simple ISR that toggles a different pin. Add a s...

Can you post a simple demo showing this? Looking at the datasheet - bits are set in IOCxP and IOCxN for rising and falling edge interrupts - both to detect both. I added an IOC interrupt to a chart and selected some pins (the 'selection' image is too small - and I couldn't find keys to enlarge it) -...

This would probably be best as a new topic - but I'll not try moving it on phone... What are you trying to achieve - what speed are you wanting to change? For app developer or for an MCU? Or do you want multiple 'tasks' to run at set intervals / rates? If you post more details possibly with some sam...

Oh dear - sorry to hear that....

It should be possible to re-instate your keyboard driver - from within Windows (right click 'Windows' -> Device manager....)

Yes - fire up a 'Dwarf' or two - from the earlier series of course. And enjoy!

Now works AOK on esp32 - the string comparison is fixed (update CAL_STRING.c)

Martin

Thanks - just tested and all seems good now

Hi, If the Pico is running FreeRTOS as the 'OS' - would it be possible to use FreeRTOS functions - such as xTaskCreate - in FC (using C blocks / supplementary code) as on the esp32? There are several examples for the esp32 on the forums - using such features as tasks / queues etc - and it might be w...
