In a way, you can mimic this using a global constant let's call DEBUG and then in each macro have a code block at the start with #ifdef DEBUG And sat the end of the macro #endif The problem might be that the macro will call other macros - dsi knocking out one actually might mean a while chain of mac...

Interrupt routines should (always) be short and as quick as possible - usually not calling other macros, but certainly not calling things such as displaying data. If your interrupt is something like: time=time+1 If time = 405 Flag = true time=0 Then it is probably not the source of the issue. Do you...

Let us know how it goes. Just looking - for the second use case you'll need to change the default destination (on my machine it is k:\ ) t he code still has a backup folder (I modified some 'backup' code) The board is neat - having just fried several chips - I like USB power solutions more and more....

Hopefully it works for you now. You'll need to set osccon for your required clock etc. You might need to adjust the speed in properties too - if FOsc/4 doesn't work try FOsc/16 - I found the displays are quite sensitive to the quality of the wiring - use short good quality jumpers if breadboarding t...

Are you setting the pins in properties (including CS) MAX7219.jpg This should run through some demo routines... I used the 18f252 but should work with others if they sufficient RAM - it uses 8 bytes for each of 16 displays (max allowed as far as I remember) Note also that it doesn't do anything in s...

... And yes, it would be good if others contributed more - and keep a more dynamic conversation going rather than getting an answer and then disappearing....

Not sure how to encourage that though - maybe small prizes for 'project of the month' ?

Blushing slightly - and I agree with Steve, there is a good community and people will help where possible. It's one of the strengths of flowcode is having a friendly / helpful user base. Steve, Ben and Martin do a great job (one place I worked the boss shouted 'Tell him I died' when one customer ran...

Can you post the code you tried? I only looked at one MCU - but the 18f252 should have plenty of RAM. What issue are you getting. Won't compile, or it doesn't work on hardware?

Which PIC did you try?

I've experimented a bit - I've tried to get an esp32 connected to a bicycle radar (Garmin). - it's possible although I used mostly c from one of the espressif example files. It then used a callback function to respond to messages received. Time pressure meant I never quite got where I wanted (a hand...
