Tandy Multiface Gertboard Compatible Interface Board for Raspberry Pi

The Tandy Multiface is a brand new I/O interface board for the Raspberry Pi designed by Darren Grant from Tandy. The reason it came about is that, back in September 2012, Tandy was marketing a Gertboard kit, having bought a supply of official Gertboard PCBs from Farnell. This was a bit of a coup because Tandy beat Farnell to the punch with their own product. Farnell struggled to get their ducks in a row (I seem to remember comments about a shortage of one of the chips) and launched their kit about a month later. […more…]

Download Python Gertboard Programs ocol – Open Collector – Darlington Array Relay Driver I’ve managed to get the open collector ocol program written in Python. The ocol program drives the Darlington Array on the Gertboard. This can be used to switch up to 6 relays, each on a separate GPIO port. I’ve managed to write versions for both wiringpi for python (ocol-wp.py) and RPi.GPIO (ocol-rg.py) They are both included in the download link, which will always contain the most up to date versions. Here’s a comparison video of Gert’s ocol program running first, then my […more…]

Download Python Gertboard Programs I’ve been having a go at producing Python 2.7 versions of some of the Gertboard test suite. It’s partly as a learning experience for me and one which I hope will help others too. Which GPIO? Why not both? There’s two different ways to handle GPIO (General Purpose Input Output) in Python at the moment… Ben Croston’s RPi.GPIO Gordon Henderson’s WiringPi (Python Wrapper by Gadgetoid) The ultimate aim is to have versions of the Python programs using both systems. As a file naming convention, we’ll take the name from the original […more…]
