Below is history using different code
Hi All,
Still very new to Arduino and coding. I have setup the following code for a receiver and transmitter
both use nRF24L01 modules, and an Arduino Nano board each.
I have a joystick attached to the Transmitter that reads the X, Y and switch states.
Viewing this in the monitor shows the values as expected, these change as I move the stick / press switch.
Position X: 500
Position Y: 500
Switch: 0
I can see the following on the Receiver monitor:
Position X: 14
Position Y: 14
Switch: 0
Only the switch responds and acts as expected, as you can see the X and Y get different numbers, however they do not change when the joystick is moved. I assume theres a different way to parse integers that maybe I don't yet know how to code?
Any suggestions / help is greatly appreciated. Thank you
Note: I did take out the checks to confirm the radio was connecting as the variables wouldn't parse fullstop. I had used a demo set of code (link below) that worked and the only thing I could see dfifferent was that it did not have the radio connecting checks.
I will need to revist this at a later stage, but for now I just want to see data from one going to the other.
