added Mbed compatibilty #30

Closed JojoS62 closed 4 years ago

JojoS62 commented 4 years ago

This is a PR for making the MD_MAX72XX compatible with Mbed-OS: https://github.com/ARMmbed/mbed-os

I like the MD_xx Libraries, but I'm using mainly the MBed-os and wanted to make it compatible. So it can be used with a lot of Cortex-M that are supported by Mbed.

It adds macros for Arduino compatibility and uses Mbed Objects for SPI and DigitalOut (for chip select). Differences with Arduino are solved by adding conditional compiling, using the presence of the __MBED__ define. It has been tested with Mbed-os 6.1.0, but should work also with earlier releases.

This first release uses only the hardware SPI object from Mbed.

Don't know if Mbed compatibility was ever requested, I don't worry when you don't want to maintain this addition.

There has not been a request for this at all. I will put this into the main branch but I am concerned that I will not be able to test or update in future versions.

Great, thanks for your support! I will provide some Example in my Repo. I've added the Mbed stuff also to the MD_Parola Lib and it is working already. I want to do some more testing and add examples for this too.
