Error! Function set incorrect in HD44780 LCD Module

Asked By 0 points N/A Posted on -


Hi there,

I try to use HD44780 LCD Module to build a module. However when the simulate is trying to run, an error message appears and it says that the function set is incorrect. Please find below the screenshot of the error message for your reference.

Can any expert explain this error and any suggestion to solve the error? Thanks in advance.

Error! Function set incorrect. DL=1 N=0 F=0

Function set must be DL=0 N=1 F=0

Hi Mario! It seems like you have not set the mode correctly, and that is the reason you are receiving the error message. The simulation of the HD44780 can only be implemented for 2-line, 5 x 8 font. So set the module to 2-line, 5 x 8 font. However, you still have to write the code that sets the module in this mode. You need to then reset the simulator, modify the code and try again.
