This is the configuration used to write and test these libraries.
The red breadbord with ATmega328P is my ISP programmer. It uses the ARduinoISP software.
The green breadbord with ATtiny45 uses all pins except reset :
- One for serial RX (0)
- One for IR (1)
- One for serial TX (2)
- One for yellow led (3)
- One for red led (4)
Both are connected to the computer by USB to serial adaptator with a CP2102 chip. I bought these board by Ebay for 0,99 US $ each one.
These boards needs a little adaptation to get the DTR on a pin. At factory this signal is provided by a hole on the layout. I replace the RST pin by the DTR signal (I don't know what is the original use for this RST pin).
I put on the tiny breadbord a capacitor on reset, like Arduino Uno.
