pyBusPirateLite

Python 3 library for BusPirate based on code from Garrett Berg. It tries to be more Pythonic than the original code.

This library allows using the following modes:

• SPI
• I2C
• UART
• Bitbang
• Onewire
• Rawwire
• ADC measurements

For more information about the BusPirate see http://dangerousprototypes.com/docs/Bus_Pirate

Based on code from Garrett Berg [email protected] (http://dangerousprototypes.com/2011/03/14/new-version-of-pybuspiratelite-python-library/)

Note: Works on Windows and Linux

Installation

Steps

git clone https://github.com/tijldeneut/pyBusPirateLite
cd pyBusPirateLite
python3 setup.py install

Oneliner

git clone https://github.com/tijldeneut/pyBusPirateLite && cd pyBusPirateLite && sudo python3 setup.py install && cd .. && sudo rm -rf pyBusPirateLite

Extra requirements

• The actual Bus Pirate device. In case of Windows, find drivers here: https://ftdichip.com/drivers/vcp-drivers/

Examples

SPI

from pyBusPirateLite.SPI import SPI

spi = SPI()
spi.pins = SPI.PIN_POWER | SPI.PIN_CS 
spi.config = SPI.CFG_PUSH_PULL | SPI.CFG_IDLE
spi.speed = '1MHz'

# send two bytes and receive answer
spi.cs = True
data = spi.transfer( [0x82, 0x00])
spi.cs = False

Bitbang

from pyBusPirateLite.BitBang import BitBang

bb = BitBang()
bb.outputs = bb.PIN_AUX
bb.pins = 0        # set aux pin = 0   
bb.pins = bb.PIN_AUX  # set aux pin = 1

I2C

from pyBusPirateLite.I2C import I2C
i2c = I2C()
i2c.speed = '400kHz'
i2c.configure(power=True)
i2c.write_then_read(2,0, [0xec, 0xf6])  # set write register
i2c.write_then_read(1,1,[ 0xed])        # read from register

Or use the custom script to create chip dump:

wget https://github.com/tijldeneut/pyBusPirateLite/raw/master/samples/i2c-dump.py
chmod +x i2c-dump.py
i2c-dump.py -s 1024 -o chipdump.bin

Detect port

from pyBusPirateLite.BitBang import BitBang
bb = BitBang(connect=False)
port = bb.get_port()
print(port)
bb.connect()
