Hello all,
I have a Rasclock sitting on my Raspberry Pi. According to spec it
uses the pins 3.3V, GND SDA and SCL.
The Rasclock itself consists basically of a PCF2127AT chip.
My question: What is the best way to access these I/O pins?
My goal would be to write some sort of driver for this device. I am
hoping that once I got access to the pins I can continue experimenting
with the data sheet.
Any help appreciated!
Best,
Holger
