Re: leds test problem

Yeah, I hooked 12 pins from the ATMega up to the 12 BUFx pins at the edge of the board. All of the in/out jumpers on the buffers are removed. There's not a whole lot of wiring to recheck. And every one of the ATMega pins is set as an output. The LEDs consistently come on when I am driving them on, b...

Re: leds test problem

They flicker even when I am using them, though. I was tinkering with the ATMega, wiring up all 12 LEDs from the ATMega pins to BUF1-12, leaving all the in/out jumpers disconnected, exactly as described in the user guide: "There is a third option for using this port: if neither the input nor output j...

Re: leds test problem

I find this behavior pretty bothersome as well. The user guide does mention that "Depending on the type of 74xx244 buffer chosen, the LED could behave randomly if the port is not driven properly." The ones that came with my kit were HC's. Anybody know which family would make the LEDs not behave rand...

Re: Gertboard and D5 not working

Wow. I had the same problem. Altering the code to use 27 instead of 21 worked, but man... I hope there was a good reason for changing the GPIOs between revisions and throwing this kind of monkey wrench into coding for RPi.

Re: Gert Board Discontinued?

All I know is, I ordered my Gertboard from E14 more than three months ago, and I haven't seen squat from them, kit, assembled, or otherwise. Their entire handling of my RPi order was pretty terrible, and I don't expect I will ever do business with them again. I just want this to be over. :(

Not anymore I switched to AVR ATmega328P.



Awesome.  I just recently picked up an Arduino and have been having a blast with it.  I'm glad some of that experience will transfer over to making even cooler things with RPi.
