API

import module
relay2 = module.get(module.RELAY2)
relay2.init_i2c_address(0x25)

• Initialize the module and specify the I2C address (default is 0x25).

print(relay2.read_status(0xFE))

• Get device firmware version information

relay2.write_relay_state(1, 1)

• Setting Relay Status:
  • relay: 1-2
  • state:
    • on:1
    • off:0

print(relay2.read_relay_status(1))

• Read relay status:
  • relay: 1-2
• return
  • state:
    • on:1
    • off:0

relay2.write_i2c_address(0x25)

• Setting the module I2C address
