hi. Last time i posted thread about my lcd problem which was not working after i connected power. Some guys suggested me to put contrast VR as i didnt put one because i didnt have that. Now i got one from ebay and i connected VR. At first it didnot show any respons. I thought it might damaged. But when i saw deeply there was blury boxes. I connected 4AA SIZE Battery. I thought these must be used. So i put new 4 batterys and adjust contrast. And then it was clearly showing that boxes. I just used the +v , 0v and contrast pin. Then i puted the other pins to get a proper output. I need to mention that i am using axe28x2 pinsC on Lcd. My project board is axe020. I puted the manual 3 Lcd (direct) commands by copy paste for my project. Now i dont know whats the mistake i made. Can anyone tell me please what i have to do? I use my mobile to post thread. So i cant attach all the ditails. Also i thing i dont understand that the datasheet says it needs 4.5 v. But when i put 3 AA battery. It still blank. Do need to put separate power for lcd?
