No, I didn't have them on the test circuit I was using on the beaglebone. Thanks for reminding me, though. I've used these chips before (http://stuffwemade.net/project/led-cylinder/) and I did need...

Hi. It's probably the library. When starting up, the library needs to select an appropriate driver for the board. Different boards support different hardware. There is a raspberry pi driver,...

Ok sweet. I don't have a board to test it on. The Raspberry Pi driver firstly detects if it applies (the test you've amended), but it also contains a function...

This is delayed as I'm waiting for a new LCD display to test against the port extender.

That's odd. There have been no changes in the library that would effect that. What device are you using? Also, have there been any updates to the device?

I've created issue https://github.com/mrmorphic/hwio/issues/53 in order to add board revisions that are currently missing from driver selection. If you're running the same code on a model 3 board, this is...

I don't remember the exact reason; it would have been because it didn't work on a test device, or it needs more work. One thing that stands out is that...

I found that sometimes I can get stuff working by writing to the hardware spec, but often when you get an actual device, it doesn't work according to the spec,...

Hmmm, is the relay connected directly to the GPIO? The maximum current for a GPIO pin is about 16mA, and non-solid-state relays typically require a bit higher than that. It...
