hi monie
append at end of file name simple with .zip
example:
orig file: test.zzz
append: test.zzz.zip
then you can upload the file
and give the info, that is only append and not compressed
hope this helps
best wishes
rudi

Hello Monie
I've made a test with my own schematic (Proteus 8.2) .
The flowvchart works fine if I choose "I2C hardware" (channel1) .
I don't see your pull up resistors (SCL ,SDA) .

Hello Dan81
Thanks for your reply.
But do not be able to get I2C to operate so it can be anything in the display.
Tried to correct but can not get I2C for Display to work!
Hope you will be helpful for a solution to the problem
