Might be a PROBLEM for you now, but it's more of a worthwhile Example with some "remaining issues".

Just a thought.

Good luck, let us know how it goes, keep posting your working code, that helps others.

That's IT!
Thanks, helped.
The code is now like this:

Code: Select all    -- get content of register 0xAA of device 0x77
    write_reg(0x20, 0x00, 0x00) -- set bank A to output

    for i=0,255 do
      print("Setting bank A to value " .. i)
      write_reg(0x20, 0x12, i)
      tmr.delay(100000)
      tmr.wdclr()
    end


And it works beautifly!
Seems like my kids are going to miss me tomorrow

Thanks for the suggestion - I am about to try - that would be my first example ever

- Sat Nov 29, 2014 6:25 pm #3557 Had no clue what a MCP23017 is, it's a I2C IO-expander with 16 GPIO pins.

I read somewhere about I2C IO-expanders with some digital AND analog IO's. Have some experience with them? Could be a solution for all the people that cry over not having a connection to the ADC TOUT pin on their ESP board.
