Bus Pirate
Description
The Bus Pirate is a low-level interface to:
- 1-Wire
- UART
- I2C
- SPI
- JTAG
- raw 2-wire
- raw 3-wire
- PC keyboard
- HD44780 LCDs
- MIDI
It includes an ADC and can bit bash these protocols at the wire level. It can also be put into UART bridge mode, acting as a simple serial port.
Reference
Our connector
brown - GND red - +3.3 orange - +5 yellow - ADC green - VPU blue - AUX purple - CLK grey - MOSI white - CS black - MISO
NB This order depends on attachment as connector is symmetrical and may be inverted.
Sparkfun Connectors
I have noticed that the sparkfun connector and buspirate uses the following mappings
black – gnd white – 3.3V grey – 5V purple – ADC blue – VExtern green – aux1 yellow – clk orange – MOSI red – CS brown – MISO
AVRDude bus pirate mappings
