SSD 1963 AND 800X480 TFT

[pilot0315]

I have been having problems with this device. All the code appears to be correct but I cannot get the whole screen to work.
Here is the documentation and code. I get pixellations on one side, good colors in the middle and black on the right.
I will upload photos tonight

Can you share more of the pictures of what it looks like? Reading the data sheet, it almost looks like the RGB that the displays Parallax uses. For example, using a TV OUT object. Have you tried to use a TV Object to control it? Or do you have to send command to the mcu onboard to display?

Take a look at this webpage Ray uses the SSD 1963 on his DVI Graphics Shield Ray has lots of Propeller code to support his board.

I have been there. I used his code to verify that the device works. I am trying to write my own code. For some reason I am not able to get full screen. I have been looking for someone who has the same device "ssd 1963" and a propeller chip who would look at my code. Right now I am trying to relearn my Saleae logic analyzer. Have not used it in parallel before. Trying to see why the commands are screwed up in my initiation process.

Thanks

It has a controller card that has to have specific commands sent in a sequence. For some reason, either my commands are not being sent properly, completely, and or dropped off.

The left side has pixels. The right side is black the center two thirds is semi operational.

I tried to get one of these as a demo from that company, but they wanted me to buy one off the website and I don't really have a use for it. I kind of thought we could do each other a favor...I develop code for their display on the Propeller and they donate one to Savage///Circuits so I can help get people up and running. But apparently that's not an option. Sorry pilot.

[pilot0315]

Yeah they are not too creative in understanding that it could boost sales.

Thanks for the thought.

I am still struggling with this thing. I am trying to relearn my saleae device so that I can check out the code. I am having problems with that. Never used the parallel function. Not triggering when sending 8 bits.

I will get it though.

Typically you would need more than 8 channels to monitor an 8-bit Parallel bus if you're trying to see the control data. For example to monitor a Hitachi HD44780 compatible LCD you would need 8 channels plus 3 for the control bus. 8 data bits plus E (enable), R/W (Read/Write) and RS (Register Select). It's the only way you'd get a complete picture of what's going on in this case.

Without monitor the E line you'd never know when a new bytes was sent unless it changed value. Without the R/W you wouldn't know which side send the byte and without RS you wouldn't know if it was a command or data. So control bus lines are usually important, though I don't know what interface this particular display has.

[pilot0315]

I called Saleae and they told me to right click on the icon that says which of the channels is rising edge etc, and you can disconnect all triggers. Then set the data collection to a high number. Run the analyzer the run the code. When you think that you have enough data stop it and it will show the parallel data.

It worked great.

Still have a problem with the tft though.
