Workshops/Bus Pirate for dummies
Bus Pirate drop-in workshop
This workshop will cover some basic protocol sniffing with the popular Bus Pirate, a flexible tool which speeds up prototyping, by providing means (monitor and keyboard) of implementing serial communication with a device at the bit level.
- Accessing the device
- Help menu
Learning the ropes
To access the Bus Pirate, via USB, we'll be using "screen" on Linux, though in theory it should work on OS X and telnet should work on Windows.
Learning the Bus Pirate language, which reminds me of l33t.
This is a statement:
You will learn what it means, and some more.
We'll go over the connectors, plus do some basic checks with a multimeter to make sure we are good to go.
Low level communication
One of these two:
- Hitachi HM55B Compass Module
- Microchip TC3402 16-Bit Sigma-Delta AD Converter
will be used.
These integrated circuits are straighforward to wire up, have a simple serial protocol easy enough to implement, so provide a good starting point.
If you have any other you would like to sniff, bring it along, making sure there is a datasheet available.
Maybe the Wii nunchuk (I2C, I think) ?
Sure. Bring it along.
