Hello i have a bad pcb design and i need to swap mosi and miso pins on my Arduino nano
I found a forum post that suggested swaping pins in pins_arduino.h
I did so but its not working. Im sure the pins are the problem because if i solder little adapter and swap the pins. it works.
Im using rf24mesh library.
Is there something im missing?
Is there another way tow swap these pins ?
Thanks for any answers .
Sure, done all the time. Cut the copper traces and use #30 jumper wire to make the correct connections.
These are defined in hardware.
You can always cut these traces and use wire wrap wire to swap PCB pins.
There is your answer
What everyone is saying is, you can't do it in software.
The only way to do it in software would be to use a software implementation of SPI instead of the hardware.
