Are we to understand that pin 5 in this context is GPIO 5 as defined in the NINA-W102 datasheet?
yes
Where can these pin definitions be found?
there is no io remaping
io 5 is the slave select pin
the 28 is the 28th contact of of the NINA module, not an io number. as you can see reset is 19th and antenna 13th
In the setup function in
sketch.ino.cpp
we find the following code:I don't see anywhere in code where pin numbers are defined, nor is there a
variant.cpp
orvariant.h
file like in a typical Arduino sketch where these numbers would normally be defined. Are we to understand that pin 5 in this context is GPIO 5 as defined in the NINA-W102 datasheet? (page 15 of this PDF: https://content.u-blox.com/sites/default/files/NINA-W10_DataSheet_UBX-17065507.pdf)Or is it GPIO28, which the Arduino Nano 33 IoT's schematic weirdly names as GPIO5 (seen here: https://content.arduino.cc/assets/NANO33IoTV2.0_sch.pdf)?
Or is it something else?
