#118669 - function set x4 Responding to: ???'s previous message |
What display are you using?
I had this same problem with a crystalfontz CFAH2004K 4x20 character display. You need to repeat the function set command four (4) times. ;call this 4 times total, mov P0, #38h ; Function Set. mov R2, #150 ; Time for delay acall habilita ; Call for enable and delay subrutine Seems funny, but it's what my datasheet (tries) to say. |
