Assemble and test prototype PCBs #9

Closed jasonwebb closed 5 years ago

jasonwebb commented 6 years ago

Now that prototype PCBs have arrived, I need to assemble and test them out. Here is the plan:

[X] Solder parts to board
[X] Program ATTiny85 using USBtinyISP
[ ] Test all features
- [x] Power options
- [X] Via ICSP
- [X] Via DC barrel jack
- [x] Via 2-pin JST jack
- [ ] Dance triggers
- [ ] Piezo
- [x] Buttons
- [x] Sensor interface
[ ] Measure current draw
- [ ] With all LEDs on full-power.
- [ ] In normal operation mode.

I'm finding that the dance triggers (piezo and button) are not working as expected. I'm betting that the 10M pull-down resistor across the piezo is also discharging the VCC signal coming from the button when it's activated. May need to add a diode, or choose one or the other. Will be testing solutions on breadboard in the near future.

Everything except for the piezo dance trigger seems to work as expected, so I've removed t from the code (d1c1867) and PCB (932612c).
