How to scan I2C module to get adress? #32

Closed airdissy closed 8 years ago

airdissy commented 8 years ago

Hello, I'm working on my first driver : grove dust sensor for which I need to know the I2C address. I can't find a similar hex adress on a similar driver since no one work on a I2C driver for this sensor. How to scan I2C device on my wio link to know the I2C adress of my grove module? I found I2C scanner but only working on arduino. Is there are any way to launch a python program on my mac OS? I have already a copy of the server connected to my wio. Other question : Is this hex adress similar for anyone with same grove module. What happend when using the I2C hub?

Thanks for help. Peter

Hi Peter, Are you using this grove dust sensor? http://www.seeedstudio.com/Grove-Dust-Sensor-p-1050.html If so, this sensor is not a i2c device. In addition, this sensor needs 5V to work rather than 3.3V from the Grove socket of Wio Link.

Hello, Maybe I would try later to power with external 5V. Regarding correct port, what should be the correct port to drive it? (Digital, Uart?) Thanks,
