It should be quite simple to call this library with inline c. Start with running the Arduino IDE examples. Do they work?
Hi, thanks! I have everything working because I did have a background in microcontrollers although I haven't been doing any for the past 13 years after a change in career (I don't think arduino existed back then, we played with Atmel AVR microcontrollers in assembly language). I inlined a different code (from Jaycar's Christmas clock https://www.jaycar.com.au/Christmas-clock
) because I bought the led screen from them and I have finally gotten text mode to work. Took me awhile to figure out about passing parameters to the inline code until I dug around the generated C files to find the methods associated with Object class... So then I figured that I could typecast from the void * from toPointer to char *. I still haven't figured out how to pass multiple parameters, but worked around it by sending a Byte and taking the lower 4 bits as x and upper 4 bits as y for setting the cursor. I am still working out how to get Graphics to work.
Just thought that this library seems to support many leds. Will it be wrapped for use in B4R?
