Raspbian/Raspberry Pi SPIandModpus issues

Using Arduino IDE 1.x
1

HI All,

Ran into some programing issues today on my raspberry Pi 3 - using arduino IDE 2:1.05-dfsg2-4.1 and Raspbian/debian 9.1.

I installed the Ethernet2 and modbus libraries, but kept getting 'file not found' errors for the library *.h files.

I was able to frx this by copying these library source/src folder files to the root of the library folder.

This fixed the library issues but I had to update default SPI library to get things100% functaional.

I am not sure if the Linux Arduino IDE is maybe a rev or so behind (as I had none of these issues on my windows box), but I all ears/open to suggestions.

Hopefully this fix helps someone out in the meantime.

The IDE in the repo is very old. You can get the latest version from https://www.arduino.cc/en/Main/Software. Be sure to uninstall the old version.

This might also be useful.
