This gallery shows the various versions of the olduino hardware and relates them to the AVR and 1802 software that support them and the appropriate eagle cad files. **Note that as of 17-02-16 the latest AVR code is olduinoII_ISPV6
Version IIB hardware with 74HC165 clocked at 3.5 MHz.. Schematic is olduino_2.0_v8e. AVR code is olduinoII_ISPVF4a**. SPI library is hspi2.
Version II hardware with 74HC165 clocked at 3.5 MHz.. Schematic is olduino_2.0_v5c. AVR code is olduinoII_ISPVF4(AVR runs 20mhz). SPI library is hspi2.
Version II hardware bare board.. Schematic is olduino_2.0_V4E, code is olduino_ISPVF3
Shield Adapter with ATMEGA integrated on same board. AVR code is olduioII_ISPVF2b, SPI library is hspi2.c/h/inc
Shield Adapter – using attiny85 to clock the shift register at 2MHz.. Schematic is olduinoshield7.. SPI library is hspi2.c/h/inc
Shield adapter. Fits on top of original olduino. clocking is OUT 2. SPI library is hspi.c. Schematic is olduinoshield5(board was olduinoshield4).. Still uses avr code olduinoispv2_2
First PCB modified to allow the 1802 to clock the master output shift register(MOSR) itself. SPI library is hspi.c/h/inc
First PCB. Programmer olduinoispv2_2. schematic olduinov3ck9r. SPI library fastspi.h/c/inc
