Subject: [9fans] Accessing GPIO pins on the Raspberry Pi
Topicbox-Message-UUID: dc6e0a38-ead8-11e9-9d60-3106f5b1d025

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
