I2c python
From Federal Burro of Information
I'm not sure why but i2c with python is a huge pain in the ass.
There are many libs:
i2cscan3.py
#!/usr/bin/env python3 import smbus import errno if __name__ == "__main__": bus_number = 1 # 1 indicates /dev/i2c-1 bus = smbus.SMBus(bus_number) device_count = 0 for device in range(3, 128): try: bus.write_byte(device, 0) print("Found {0}".format(hex(device))) device_count = device_count + 1 except IOError as e: if e.errno != errno.EREMOTEIO: print("Error: {0} on address {1}".format(e, hex(address))) except Exception as e: # exception if read_byte fails print("Error unk: {0} on address {1}".format(e, hex(address))) bus.close() bus = None print("Found {0} device(s)".format(device_count))
