Boils down to: not supported at the moment.

A = X & 0xFFFF
B = ( X >> 16 ) & 0xFF
C = ( X >> 24 ) & 0xFF

Check https://www.matrixtsl.com/mmforums/viewtopic.php?f=7&t=22569&p=104899&hilit=1.024#p104899 as an example on how to do this. You need to make sure your controller has a real stable reference voltage and not something that depends on voltage powering it. Should be easy recognizable by the voltage...

By changing the supply voltage you change the reference voltage used by the pic and the voltage over the divider. Both drop by the same percentage. You need a stable reference voltage to be able to see any change.

Are you calling display functions in the interrupt routine? If so, remove them, interrupts should be short and not use display components as those are too slow.
In the interrupt set a flag and/or add any received data to a circular buffer and handle that in the main program code.

Please post the code you have when asking for help.

Is this homework from a course?

This sounds like an assignment for education. Is it?

Do you actually display anything with that background? Just setting the background does not change the currently displayed information.

You should set the clock in the properties to 32MHz.

Running both FC7 and FC8 on the same PC should not be a problem.

I might be daft, but how does

FC8 components are slightly larger and as a result more memory is required.

suggest it is not a memory issue?

The compiler is the same for both version, however the components are not. FC8 components are slightly larger and as a result more memory is required.
Could could you look at the FC7 compiler output to check how much memory is being used and how much is available?

The eBay add uses strange names for the pins of the SPI interface. Sda and scl look more like i2c to me.

Use the credentials you use for your Matrix account on the main website, not the forum. That works for me. Same credentials work for the V9 forum.

We could, however forum members do not write school assignments for students. That is an official policy.

If you suggest how you want to solve this we can provide feedback and help you if you get stuck.

So how would you approach this?

Keys for old versions are not available for online purchase afaik. You will need to contact sales. However fc9 will be released in a few days (if everything goes according to plan) and at that point fc7 will no longer be supported, so do you want to spend money on it?

A bummer? Having software control of the oscillator is a feature. At allows you maximum flexibility.

What are the oscillator settings in your flowcode project?

USB with 1 MHz clock? That does not sound like a setting that would work (from memory).

Keep in mind the boot loader sets the oscillator and you might not be able to change those settings in your code. Try matching the boot loader settings in your program.

Have you set both monitors to the same scaling factor?

Having issues posting on the microchip forum does not mean you should post messages unrelated to flowcode on this forum.

Are you willing to pay for this project? If not it needs to be moved to another part of the forum. If you do, please provide more detailed specifications.

Does your flowchart contain C code to set the oscillator settings?
