A useful i2c Python3 package for Pi

It is a simple I2C interface based on smbus2.

1. Installation

Via pip

pip3 install pyi2c

2. API and example

2.1 I2C(bus_n)

from pyi2c import I2C
# Create i2c
BUS_N = 0 # 0 or 1 or 2. Change this to yours
i2c = I2C(BUS_N)
ADDR = 0x38 # Change this to yours

2.1.1 status_code

Return

  • {StatusCode.success: 0}
  • {StatusCode.ready: 1}
  • {StatusCode.fail: 9}
print( i2c.status_code )
# => {StatusCode: 1}

To get the value, use .value

print( i2c.status_code.value )
# => 1
if i2c.status_code.value == 1:
print('ready')

2.1.2 scan()

Scan all I2C devices on the same BUS.

Return list of integer (address in byte)

print( i2c.scan() )

2.1.3 write(ADDR, data)

Return nothing

  • data can be a byte or list of bytes.

i2c.write(ADDR, WRITE0)
# or write multi bytes, up to 64 bytes
WRITE1 = 0x01 # Change this to yours
i2c.write(ADDR, [WRITE0, WRITE1])

2.1.4 read(ADDR, byte_size=1)

Return integer (a byte), or list of integers (bytes) if byte_size >= 0

  • byte_size can be empty (default is 1)
read_data = i2c.read(ADDR)
# or set length of reading bytes
byte_size = 2
read_data = i2c.read(ADDR, byte_size)
print( len(read_data) )
# 2

2.1.5 writeread(ADDR, data, byte_size=1)

Return integer (a byte), or list of integer (bytes) if byte_size >= 0

  • data can be a byte or list of bytes.

2.2.1 status_code

As the same as status_code in I2C.

2.2.4 writeread(data, byte_size=1)

As the same as writeread(addr, data, byte_size=1) in I2C, but does not need address.

2.3 getBit(byte, bin_n, bin_m=-1)

Return integer (a bit or bits)

  • bin_n should be >= 0
  • bin_m can be empty (default is -1 but will overwrote with bin_n)
  • bin_n or bin_m can be larger than byte's size
from pyi2c import getBit
byte = 0x5a # Any byte data
print( bin(byte) )
# '0b1011010'
  • Get bit #n of byte
print( getBit(byte, 0) )
# 0
print( getBit(byte, 1) )
# 1
  • Get multi bits from #n to #m of byte
print( getBit(byte, 4, 3) )
# 3 = 0b10

2.1.1 status_code
Return
  • {StatusCode.success: 0}
  • {StatusCode.ready: 1}
  • {StatusCode.fail: 9}
print( i2c.status_code )

print('ready')

2.1.2 scan()
Scan all I2C devices on the same BUS.
Return list of integer (address in byte)

Return integer (a bit or bits)
  • bin_n should be >= 0
  • bin_m can be empty (default is -1 but will overwrote with bin_n)
  • bin_n or bin_m can be larger than byte's size
from pyi2c import getBit
byte = 0x5a # Any byte data
print( bin(byte) )
# '0b1011010'

  • Get bit #n of byte
print( getBit(byte, 0) )
# 0
print( getBit(byte, 1) )
# 1

  • Get multi bits from #n to #m of byte
print( getBit(byte, 4, 3) )
# 3 = 0b10
print( getBit(byte, 3, 4) )
# 3 = 0b10, the same as previous

  • Recommend usage
if getBit(byte, 4) == 0b1:
print('hoge')
# 'hoge'
