Thanks!! That worked!!

Im using FastLCD to make graphics, but the code format is incorrect. Did you have to manually convert the code or is there an automatic converter you used?

I used GLCDtodopic (attached) to make the splash screen.

BTW, it has a built in font converter.

I re-created the Gear Position Indicator schematic (see attached) and it works great while on the bench. As soon as I put it on the bike it screwes up the signal coming from the Gear Position Switch to the ECU. It seems like voltage divider drops the voltage required by the ECU. Is there any way around it?

Is there a way to output certain voltage from PIC?

Here is my code:

For a few dollars more you add Touchscreen also and eliminate buttons.

http://www.circuit-ed.com/128x64-GLC...en-P146C8.aspx

In late December we will also have the same GLCD with true RGB backlight and the Touchscreen built into the back PCB with a single 25-pin (2.54mm) at the top.

Try to change the 10K resistor (R2) in the circuit you have attached for a 100NF capacitor.

Nope. Doesn't work. The divider won't make 1/2 ot the input voltage...

Hi people,

first of all, congratulations for this great forum,
second, sorry for my bad english....

I have a Suzuki gsxr 750 from 1996 that has the GPS sensor and i've found the correct wire.

and i am using the same schematic of http://w.box.net/public/npssr2ijfj (gramo)

I've tested in Proteus and it seems to work ok, but i cant makt it work in proteus with a external xtal of 20Mhz.

I am not using the LM LCD.... I am using a "POWERTIP pc1602F B" and the best tadasheet that i've found from it is http://w.cec-mc.ru/comp/lcd/powertip...U-FWA-H-YV.pdf

Does this lcd work with "our" schematic?

I cant get the circuit working....

Can sameone give me a help?

Thanks.

Edit..... I've read some things about this and the problem is that this lcd has not an "interpretator" (i think) it is form HD44780 family..... can anyone please help to use it with Gramo's schematic (video)?
