Re: Gambas

tomtor's analysis is that there's a bug in the ARM version of Gambas. He's reported it to the developer and from what I can see that's all that can be done unless somebody else is up to debugging the code.

So the answer is to use something else until it's been fixed.

Re: Status of SD card compatibility - What should I buy?

<t>My guess is that your problem with a class 6 card is different.<br/> <br/> The fix was for class 10 cards.

Re: Would the PI be able to control something like this? (USB Relay board)

That board seems to have a 5V input, the Pi GPIO pins are 3V3.

Velleman do some useful USB I/O boards and kits that may be worth a look. K8055 rings a bell.

Re: Status of SD card compatibility - What should I buy?

I had a look at the Git repository and from what I can see the change was made about a month ago and is in the current Debian distribution.

I don't have a Pi so can't do any tests for myself, but people seem to be reporting that class 10 cards are OK.
