Help LCD

[mister_e]

Did you tried with a slower baudrate like 2400 bauds?

on the Pic18f2620 side, which osc speed are you using?

Are you sure LCDScreen pin is not an open collector type?

any chance to see some code snip of your PIC18F2620 side?

When you say nothing work... you mean absolutely nothing.. not even some garbage character?

Yes it work the lcd but all character i send to lcd does not respond

the only i see is black blocks.

Seems to be a contrast issue to me.

Could be... but it doesn't explain why the first LCDOUT works huh? Well that's what my half-smart brain tell me

I feel a baudrate issue, timing issue... never dared to calc the amount of time required for a LCDOUT and to receive a BYTE though. I may try it... later

I tend to use USART so far... this 2 bytes buffer is often handy...
