In Arduino mode, the OpenCM-904 already has drawn out nicely 2 SPI Ports on its two headers. In the file "SPI.h", Line 114, I saw that SPI is defined as extern SPIClass SPI; Then in the file "SPI.cpp" ...

I have code that has been working for a long time. It uses hardware SPI to communicate with a couple devices. After updating from Arduino IDE 2.0.4 to Arduino IDE 2.1.0, hardware SPI no longer works.

Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

So here’s the thing: Arduino’s built-in memory is tiny. If you’re just blinking LEDs, no problem. But the moment you try to log data, say battery usage, temperature over time, or GPS coordinates, ...
