Car Display from old Ericcson A2628

[ritvarsrizikovs]

On some Opel Vecta '94 is very bad wach. In Vectra it is too. I found old Ericsson A2628 display and use PIC16F876. Interface between PIC and display is very simple (see datasheet). I build font tabel in PIC code and use SW I2C to comunicate between LCD controller and PIC. Only problem was with very long strings to I2C (to clear LCD or to fil with some pattern).
In PicBasicPro I2CWRITE is no possibily to create as for for cycle.

Like PROTON+
BSSTART
for x = 0 to Y
...
...
BUSOUT
next
BSSTOP

But in finish i send many times the same inicialisation and command and LCD works, slow, but works.

I use ADC for voltage measurement and 2 DS18B20 digital thermometers for Indoor and Outdoor temperature. On PBP all works perfect.



If any have some q or can help me with I2C long strings write here or [email protected]
