I figured it out using this resource:
Had to add jumpers to the buffer chips (B1,B2,B3...etc) OUT.
Received the board and it is plugged in proper, both plug rows seated and the board oreinted as per the manual.
Have my jumper wires (GB to B) in place and double checked.
Unzipped and compiled Gertboard test software.(jan 2013 ver)
When I run the leds test program all the leds blink instead of in sequence like I have seen on various youtube videos.
Am I missing something? Jumper wire or jumper plug?
Runninng RPi ver7 with raspian and the new gertboard with the surface mount LEDS.
I am going to keep digging for an answer but...
Any ideas would be much appreciated.
The Gertboard will plug directly onto the Pi's GPIO pins, so you don't actually need a cable. If you want a cable, the last comment on this page tells you where to get it http://www.element14.com/community/docs/DOC-51726/l/assembled-gertboard-for-raspberry-pi
Is it coming with the ribbon (26 wire cable) to connect it to the pi or I have to buy the cable separately?
Hello again. I just recently received a gertboard and was able to install the arduino IDE, but I cannot read the chip number on the Atmega so don't know if it's a 168 or 328, so how do I set up the IDE? Thanks in advance fo the help.
Hi, The coocox software is only Windows compatible but you don't need it to experiment with the Gertboard. The supplied software is for programming ARM Cortex M micrcontrollers - neither the Gertboard nor the Raspberry Pi use this type of processor. If you go to http://coocox.org you will find a couple of boards that can use these tools. I suspect the disk was included with the Gertboard to encourage designers to try these boards as well.
As commented further on, if the gertboard is touching your ethernet plug it's mounted the wrong way round. When properly mounted one of the plastic legs on the gertboard will probably need to be removed - it will be sitting on top of the audio connector. I think this would be true, but in fact I've made up my own ribbon cable.
I got a header from Element 14 (part is TE CONNECTIVITY / AMP - 2-111446-0 - HEADER, IDC, NO LATCH, 26WAY) costs about $5, which connects to the Gertboar. Also a female header (E14 part TE CONNECTIVITY / AMP SOCKET, NOVOLATCH, 26WAY, but I already had one, from a local electronics store). This connects to the pi. Plus a scrap of ribbon cable - I bought 1 metre from Element 14 (about 8 bucks). If you make your own cable (which is dead easy) be sure that you get the connectors the right way round. There are small arrows on the headers and you should align these with the coloured strip on the ribbon cable. Also arrange the the ribbon cable comes out the right side of the female connector so it comes out of your pi case rather than goes back over the pi (if that makes sense).
Now my pi is in its case and my Gertboard elsewhere in my desk. And I didn't have to unsolder any headers.
