I verified that the value I write to the data port shows up on the pins to the LCD.Then I wrote the following code but did not get any green (or any changed) pixels. // Define an area of 100 Pixe...

Yes. I have two identical boards. They both behave the same, that is I only get a white screen that does not change when I run the code. I have tried a few things. I swapped the display between...

Here is a link to the connector that I am using to attach the LCD to the board: http://www.digikey.com/product-detail/en/FH28-40S-0.5SH(05)/HFV140CT-ND/2119015. It is a 40 Pin Bottom contact 0.020...

FYI Here is the board I am working with. The connector on the left of the screen is where I am measuring the voltages. For some reason the picture shows stripes on the screen but it is really jus...

The display is basically white. There are no colors. Nothing is ever displayed on the screen. I have gone through the code I am using again and very carefully compared it to the code you said wor...

Yes, I can adjust the brightness of the backlight using the two transistors. Yesterday I ohmed out all the grounds at the connector and then measured all the power lines. Every connection looks l...

I changed the code to match, very closely, to the code you posted. I also matched the timer/delay (I am assuming that the number represents milliseconds). I still do not get any response (any cha...

Thanks Michael_L. A quick question as I start to go through the code. It uses RS. This version of the display does not use an RS but a D/C (data or command). It is a major change since the last...
