\subsection{Connecting to Programmer} |
|
|
|
These notes may be redundant, need to double check. |
|
|
|
|
|
|
|
When connecting, have a base setup that works as a sanity check. |
|
|
|
|
|
|
|
It may be possible to blow out atmega328p pins if you leave attiny running, thne |
|
|
|
plug in the cable back to front (i.e. pin 13 in 9). |
|
|
|
|
|
|
|
You might need to reboot the arduino completely. |

From Programmer Source code: |
|
|
|
- Upload to arduino and power off |
|
|
|
- Connect ATtiny10 as shown |
|
|
|
- Power on and open the serial monitor |
|
|
|
- If things are working so far you should |
|
|
|
see "NVM enabled" and "ATtiny10/20/40 connected". |
|
|
|
- Input one-letter commands via serial monitor: |
|
|
|
|
|
|
|
This programmer is not foolproof, so establish a routine, and keep a working |
|
|
|
model (pcb w/attiny) as a prototype to isolate what is broken. |
