LED2472G with Arduino (sample code)

mikeinjapan over 4 years ago

Hi,

Does anyone know of any sample Arduino code (or libraries) for controlling the LED2472G?

I seem to be going around in circles with it and can't seem to find any example code.

Thanks,

Mike

I tired to find something but didn't have much more luck than you. However the Rasperry Pi Sense hat uses an ATtiny to drive a LED matrix using the LED2472G. Their setup is done from a C program, but the draw loop is written in assembly (maybe this could help for figuring out how to initialize the device?). Reading the datasheet for the device it seem like you're selecting which register to write by delaying the number of clock pulses before LE goes high, so I'd probably start there.

I have a feeling that I'll end up falling back on a Cypress PSoC as an easier alternative (SPI and LE asynchronously via hardware, control in firmware).

I'll post how I get on.
