Blinkie step one
Oct. 18th, 2010 09:37 pmI fixed the wiring bug that I had in the basic charlieplexed prototype that I put together over the weekend. The wiring is confirmed OK. I also drew some charts by hand to make sure I understood what was going on.
Then I got the STK500 development board powered up and a ATTiny13 chip installed and jumpered properly, and wrote a 4 line test program to just blink the first 5 LEDs on and off.
The major issues are:
- figure out how to do deep sleep mode and how to wake from it with a switch on an input
- build an interrupt driven charlieplex display driver.
These are really the only two issues. Doing the patterns and stuff on top of this will be pretty trivial.
Then I need to learn how to use Eagle CAD to lay out the board. I do know a couple of guys at work that have done that before though so I have a resource.
