Bus Pirate Demo Board v5 design overview
From DP
[Available for $xx.xx at Seeed Studio].
Prototype PCBs are available in the free PCB drawer.
Bus Pirate Demo Board v5 is a multiple protocol, multiple IC emulator. To test out major functions of the Bus Pirate we programmed one microcontroller to emulate various different devices you could connect to the Bus Pirate. By selecting different combinations of jumpers you are in fact changing the function and the interface protocol of the board. It can emulate the following functions:
- PWM generator
- ADC converter
- DAC converter
- SRAM memory
Communicating with the Bus pirate over the following protocols:
- SPI
- I2C
- UART
- TBD (to be decided)
