I have taken the Open Source Christmas Tree Ornament project from Brian Schulteis and put it on GitHub under newmatik/Weihnachtsbaum (please Fork!) with a couple of modifications:
- Added 20mm cell battery (CR2032) as power source so the ornament can work without being connected to permanent 5V through cables
- Added a LDO Voltage Regulator (LP3985IM5-5.0/NOPB) to convert our 3V into 5V
I believe I have done that correctly. However now I want to do the following and I am stuck since this is my very fast Eagle project and I am not an Electronics Engineer:
- Adding the Tag Connect TC2050-IDC-NL and wiring it correctly to J1 (2x6 connection header). I did not find a good instruction on what pin goes where and it doesn't seem like it is 1-1, 2-2, ... 6-6. I find the Tag Connect makes it much easier to connect the PCB for programming.
- Enable SMD tactile switch to (1st click) switch device on all lights on (2nd click) LED blinking effect every 3 seconds (3rd click) LED cycling various effects and (4th click) turn it off again saving battery. How can I switch on the ATTiny45-20SUR and make it enable to input logic of the LP3985IM5-5.0/NOPB? Do In need a ATTiny with more IO for that?
