I Have been working on a project to control a I2C LCD & for the most part it seems to working fine. I am having some trouble reading the busy flag but it may still be a code issue.
The thing i was surprised to see was I2C waveform with its spikes & not returning to ground fully in some cases. Has anyone had this issue?
Using: Peter Fleury's library with my code.
Pull up Resistors: 4.7k & tried other values.
