#1 Post by PaulC » 05 Mar 2008 21:20

i'm using big avr board atmega128 card
glcd demo works when glcd in board connection
i'm assuming ctrl is 2, 3, 4, 5, 7, 6
and data is port a

sub procedure Glcd_Init(dim byref ctrlport as byte, dim cs1, cs2, rs, rw, rst, en as byte, dim byref dataport as byte)

Glcd_Init(PORTE, 2, 3, 4, 5, 7, 6, PORTA)

but nothing in adapter..?
multimeter all pin's they are fine
volt's 4.9 fine.. both from board and ribbon...
got me stumped ?? :?:

Glcd_Init(PORTE, 2, 3, 4, 5, 7, 6, PORTA) 'works on bigavr board

Glcd_Init(PORTE, 0, 1, 2, 3, 5, 4, PORTA) ' for parallel adapter

parallel doubles the screen
i.e. 50 x 62 twice would be great if i was crosside..
with or without pullup the same


works fine on big avr board 128 x 64 1 screen..
:?: :?

Hi,

I used our GLCD Test example provided with mikroBasic for AVR

Code: Select all

Glcd_Init(PORTE, 2, 3, 4, 5, 7, 6, PORTA)
GLCD works with this line and parallel adapter.
You just need to set the correct pin out.
I used mE Smart ADAPT2 board.
