Why am I getting this nRF24 error

[joneox]

So I added to my code the ability to read the 2s voltage, but suddenly it stopped working

• When I upload the previous version, it works, but when I upload the new version, I keep getting this error

[xfpd]

Where are all the differences in the two programs?

Do not use the new version. You are probably connecting voltage to places in a range it should not be. Show your wiring diagram.

@joneox

if (0)

If never...

@xfpd

Where are all the differences in the two programs?

I had a quick look just using fc in windows cmd line. Here's the output from it.
diff.txt (2.2 KB)
I don't have time to look at the diff now, just browsing while I had 5 mins to spare whilst waiting for something to finish cooking.

[joneox]

I think I will start again from the previous version to see what's gonna happen...

Request for Information to Assist with Your Problem:

I find your question interesting, but I have a problem understanding your setup. After reading your description, I still have no idea what your actual configuration looks like. To help you better, please provide the following:

1. Annotated Schematic: Post a clear, annotated schematic of your setup showing all connections, including power, ground, and any power supplies. I do not work with Fritzing diagrams or unclear pictures. However, a readable photo of a hand-drawn schematic is perfectly fine.
2. Technical Details: Provide links to the technical information for all hardware components used in your setup. There are many different and sometimes incompatible devices that look similar but behave differently, so it's crucial that we have accurate information. Avoid linking to marketplace sites like Amazon that often lack detailed specifications.
3. Why This Matters: All you want is to make everything work together correctly, and all we want is to help you achieve that. By providing the correct details, we can offer more targeted and effective assistance.
