It looks like you need to have the Simulation Speed (in the Simulation Debugger window) set to "Fast (with updates)".

This is part of Flowcode that has not been looked at in a very long time, so I will add it to our list to investigate and see if we can have this working better.

Have you got a simple LED flasher project to work on your hardware? That would be the first step.

Then, try to isolate the exact issue that is not working. For example, is it just the interrupt firing that is a problem, or is there something else?

Thanks. It looks like there could be an issue with that LCD component that is preventing it from using the software SPI channel. Hopefully we'll have a fix soon.

Thanks, Martin, for this workaround. It looks like this chip has a special mode for PWM when that OCR0A register is set to zero, and the PWM CAL may not support it. I'm not familiar with that chip and its datasheet has a lot of text relating to the various PWM modes, so it seems pretty complex to me.

Ok, I think I can see what you need to do. You basically need to replicate the settings in the "<build> <programmer>" setting that is near the start of the FCDX file of the chip you are using. For example, if you are using the "ESP32-S3_MINI", that entry in the FCDX file is: <pro...

I think you need to make a copy of the existing v11 "esp32_prog.bat" batch file and make the following changes near the beginning of it: @SET BASE_DIR=%~2 @SET TARGET=%~3 @SET OUT_DIR=%~4 @SET PORT=%~5 @SET BAUD=%~6 @SET CONFIG=%~7 @SET CHIPTYPE=%~8 And the Arguments string within User Too...

I feel a need for speed!!! The in-built port i/o functions in Flowcode have many compromises to account for all the different family and sub-family types and so are not necessarily optimised for speed. For example, I think TRIS is always set even though this may be unnecessary. Flowcode's focus is ...

And I remember seeing that odd symbol when using those old drivers, but IIRC it did not prevent the drivers from working properly.

Those boards are very old and I don't think I have access to any, so I can't test. You might get some luck from searching our old forums. For example, I found these: https://www.flowcode.co.uk/mmforums/viewtopic.php?p=107881&hilit=eb006+driver#p107881 https://www.flowcode.co.uk/mmforums/viewtopi...

I'm not too familiar with ADC sampling on that particular chip, so bear that in mind and hopefully others will have a better answer. If it were me, I would first read at 12 bits and see if the speed is acceptable. It's probably not much of a difference to the speed, and there could be greater saving...
