Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.
During this interim period donations and continued membership are greatly appreciated while we transition to our new space.
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.
