Wiring
- Vcc can also be 3.3V
- C1 can have bigger capacity for unstable voltage
- R1 can be higher values
Programmer
I have an USBasp. Program with avrdude. Works integrated in Arduino IDE.
Numbering of Connector is
1 3 5 7 9 2 4 6 8 10
Need to connect Vcc, Gnd, Miso(1), Mosi, Reset and Sck
New chip needed 0.5MHz for correct timing with delay()
Needed this in file /etc/udev/rules.d/50-USBasp.rules
