Henri,
I initialize the lcd but i don´t get to send information.
I need send the color table before??
You can help send the color red?
Thanks

here i send the 02h to lcd, but lcd stay white.

hi im trying to do a library for PCF8833 with a PIC18F2520, but i cant init my display this is my code, whats wrong?

...

Thanks for your help!

ive modified the code (up), but ive the same problem... im trying to put all the screen in red.

xao!

nobody?? please ive compiled the code more than 100 times!!

thanks

Jim,
try use the invert mode comand 21h . I can initialize, but a have the same problem, i can send x and y, invert lcd.
The colour nothing, only clear lcd with colour white.
look in

http://www.apetech.de/nokia6100.php

ive found a 'little' error into the output of bits ..... its modified in the code below.

now lcd seems to do 'something' but... no color! its suppouse im drawing a red background but.... nothing append.. ill try with invert mode...

thanks gafar!

I had the same problem when using the EPSON version of the screen. When i initialised the screen it comes on with a dull golden glow. I solve my problem by adjusting the voltages to the LED+ pin (pin 10). My volatage was too high making the contrast too high so I couldn't see any changes to pixels. Lower voltages should help.

thanks for your reply llornkcor, im using philips version (brown board), and i think there isnt a problem o led voltages, i try with a low level and a high level and... nothing append...
thanks

It is already about year since I last worked with these displays so I don't remember anymore how things exactly work. To refresh my memory I would have to read the datasheets again.

But these links posted earlier look like they would have some nice example code to use and see how the initialization and other things work.

I will bookmark these for myself to have a closer look when I next time work with these displays.

thanks henri, now i can send images to the display (was a stupid wire...) ... ill finish the library with PIC and ill post it.

Salu2!

hi!

Henri, ive a problem with mi library, when i send an image to the display, that is my result



As you can see, the img ist complete, the functions are this:

void gclcd_img(void)
{
gclcd_setarea(X_START, X_END, Y_START, Y_END);
gclcd_cmd(MEMWRITE);
for(i=0; i<(PIXELX*PIXELY)/2; i++)
{
gclcd_data(imagen[i]);
}
}

imagen code:

static const unsigned char imagen [19200]={
0x42, 0x4D, 0x3E, 0x47, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x04, 0x00, 0x00, 0x28, 0x00......... continue until 19200 hex values...

Thnks!

Hi all,
I can to send data to lcd after use comand the contrast. Next step is send image.
Thanks the all for help-me.

Hi,
This my first work with lcd. I damaged the leds because i don´t used resistor.

hi all! im publish a preliminary version of my library v0.1 with a pic18F
http://foros.solocodigo.com/index.php?showtopic=13883

im looking for a program, or source code (PC) that convert an image (bmp 256) to RGB8 .. and hex values... in other words... a simple converter rgb8 with an output in hexadecimal...

thanks!

Hi,

See this rgb8 convertert.
I not tested it.
