- Mon Aug 01, 2016 4:37 am #51880 Just a quick & handy I2C scanner program that can help you with your I2C devices:

Code: Select all     for address = 1 to 127
       i2c.begin(address)
       stat = i2c.end()

       if stat < 1 then
         ' print stat
          wprint "Found I2C device at address: 0x" & hex(address)
          wprint " - > " & address
          wprint " <br>"
     endif

    next
    wait

Please keep in mind that in ESP Basic you have hardcoded I2C pins yet, SDA -> GPIO0 and SCL -> GPIO2.
Don't forget to add if needed pullup resistors on both lines, 4K7 should be OK.

More things related with ESPBasic I2C drivers implementation will follow, where do you think is better to post them? Maybe a Tutorials section?
