Importing Arduino library files into PYNQ?

Question

Hello,

Does anyone here have experience with taking Arduino .h file type and was able to modify it to be used with pynq and juptyer? If so, could you include a modified file and the original file it was based off of, so i can take a look at both to understand what changes are needed to be made.

I know there is a document on the pynq website that explains how to make a header files but at least for me its not easy to follow. Here is the link to the document i am referring to:

Thanks

Not sure if you have seen it or not but there is an example included with the PYNQ-Z1/Z2 build on using the Adafruit 1.8" LCD (Arduino) Shield on the PYNQ-Z1/Z2 and accessing it with Jupyter Notebooks.

Arduino_LCD18 notebook:

https://github.com/Xilinx/PYNQ/blob/master/boards/Pynq-Z1/base/notebooks/arduino/arduino_lcd18.ipynb

source:

https://github.com/Xilinx/PYNQ/tree/master/pynq/lib/arduino/arduino_lcd18/src

Looks like it started off as a MS432 Launchpad project which Adafruit then adapted for use with Arduino, and which then Xilinx adapted it for use with PYNQ.

However, perhaps you can compare the Adafruit Arduino code with the Xilinx PYNQ code to see what changes were made.

Note that this PYNQ example appears to relate to the original v1 version of the Adafruit 1.8" LCD Shield and not the current v2 version. In the v2 version, Adafruit changed the analogue based output for the joystick switch to a digital I2C output using their 'seesaw' interface, and added three additional input buttons.

There are a couple of additional Arduino shield examples in the PYNQ build for the Sparkfun 14180 'Ardumoto' and 9760 joystick shields:
