LCDOUT custom commands - how to?

[Darrel Taylor]

PBP uses FLAGS.1 (LCDINITFLAG) to remember that it's already initialized the LCD. By setting it to 1, you can make PBP think it's already done, then you can go ahead and do the init manually.

I don't think the Proto-Board itself would cause the display not to work. But I do agree with Keith in that somewhere along the line, something was probably wired wrong, then both displays were tried, and now both displays are most likely dead. It only takes a couple ms of reverse power to fry them.

The reason I say that is because LCD's that haven't been initialized always show black squares on 1 line. From what I understand, you don't even get those.

It may be time to cut your loses, and move on.

Well Darrel,

Thank you for the clarification.

I have sent the displays back to the supplier so they will test them.

It's the first time I have tried to use those COG displays and heard from other collegues that they are quite fragile.

Let's wait.

Thank you All for your hudge support (I'm just surprised how many ideas all these guys have to solve a problem!!). Hope to come back with good news.

Hi Flotulopex,

I have tried to initialize a DOG-M Display without success by now.
How did you carry on with your display - was it defective?

Hello Inse,

I bought a new display and it did the same (= not working).

I then wrote to the supplier sending him my code and shematics. The supplier asked me to contact their subcontractor in Switzerland.

I did so but never got any reply.

Meanwhile I put this projet by side and still have two displays that never worked up to now...

I'l try to contact the supplier again.

What display have you got and how did you connect it? Have you a shema to show?

Hello Roger,

its a pity that the Swiss distributor gives so little support.
Finally I got my display working.
With a wild mixup of PIC BASIC and bit-banged initialisation the LCD could be accessed by the standard BASIC commands.
By the time I have analysed the problem and found an elegant solution I will give you feedback, schematics and code.

Regards,

Ingo

Hello Inse,

Could you please send me your solution?

I still can't make my displays work....
