Four Letter pHat - Any C Examples?


#1

Hi,
I’ve just got a Four Letter pHat running on a Pi Zero WiFi. It’s a great product.
I am wondering if there are any examples of controlling the Four Letter pHat using ‘C’ as I do not usually write code in Python, use to writing in ‘C’ on for the Pi?
Look forward to getting comments.
Regards
Phil

Not that we’ve written, but Four Letter pHAT is driven by an HT16K33, which there should absolutely be a C driver for somewhere.

Looks like there’s even an upstream Linux module for it, though I don’t know how useful it’d be: https://github.com/torvalds/linux/blob/master/drivers/auxdisplay/ht16k33.c
