Design Tips
Question 1:
Answer 1:
Ensure that you have the control bits in the LCDSE properly configured, since these bits override
the TRIS bits.
Question 2:
Answer 2:
Your frame frequency may be too low. The frame frequency can be changed in the LCDPS
register.
Question 3:
Answer 3:
This may be due to misadjusted LCD voltage, some possibilities include:
1.
2.
If you are using the R-ladder, try different values of R, vary the R-ladder potentiometer.
The VLCDADJ pin should be connected to ground.
If you are using the charge pump, adjust the resistance value on the VLCDADJ pin.
I’m trying to use some of the LCD pins as inputs.
My LCD panel is flickering.
The LCD segments are not very visible.
