  1. Update - bugfixed code! I checked in my revised version to GitHub. This adds a resistor pulldown to the clock input, changes to MSB-first to be compatible with the nRF radio chips, and fixes a bad pin for the test output. HINT: If you edit the GPIO pins in the P1/P2 section in Grace, and make a mistake, it doesn't fix it when you then edit them in the other modes!
  2. Halloween comes round, and I can't face all that orange goo everywhere.... so I went cardboard. Rectangular things are easer. What about doing a cube? Oh, yes! And, of course, it needs some good lights: The 5mm round LEDs are RGB, the larger ones are high-brightness white. These are driven with a high pulse current to create the impression of lightning. Code is here: Video:
  3. Hi - heres a diagram to be going on with. I'll produce better documetnation shortly...
  4. Now I have a launchpad, plus a pile of G2xxx devices. A little shopping accident happened at Farnell :-) Finding the time ot catch up on 20 years of tinkering, now the kids are a bit older.
  5. So you now build all of your projects on breadboard, and the Launchpad just gets used as a progammer/debugger adaptor. The 20 pin DIP socket gahters dust. I have put this to use by writing a SPI-UART adaptor that runs on a 2553 in the DIP socket, while using the Launchpad to debug my project. The project code can thus output console data using a bit-banged SPI output. This only consumes port pins, no timers or UARTS, and is not timing-critical, as the data output is synchronous. This shows how you would use it: ... and here it is on my desk... Code is at https://github.com
