Hello, I have an issue with a sketch made for operating a stepper motor with a Bourns rotary encoder and an LCD to display position and I have received this error:
no matching function for call to 'ACE128::ACE128(int, int, int, int, int, int, int, int, uint8_t*)'
I know this is probably and easy fix but I just can't seem to get my head around it. I've tried to reach the original author but have received no com. Keep in mind that I am a new coder and would like as much info about this that anyone will give. I have spent a few hours reading forums, searching the web and just looking for code that is similar that might help.
Thank you.
Here is the code:
