I am glad it is running now. It is not a chip I have used, so you will have to sort it out, now that you are communicating with it.
If you do need to remote it in the future, you should use shielded cable with a good ground, increase the size of the bypass / filter cap at the IC, from the 0.1 uF to something much bigger, and also reduce the value of the pull-up resistors at the IC from the current 10K to something down in the range of 1K to 2K. But still keep that cable length as short as possible. Good luck, --- Graham == On Mon, Mar 13, 2017 at 7:56 AM, christ christ <[email protected]> wrote: > Thanks Graham, got it working.
