ssd 1963,newhaven display

pilot0315

A few years ago I bought a newhaven 7 inch tft. Had growing pains with it in spin. I was trying to port the arduino example code to spin. Got pretty close but had issues. Recently leaned Propeller C, C and C++. Went back to the project and have an issue. Andy Lindsay did help. But I still got a problem.
I am able to initiate the screen but not able to paint it. My old Spin code and the C code initiation sequences are identical and work. I use a repeat sequence in Spin to paint the screen but it has issues.
I am uploading the Arduino code and Propeller C code as well as Spin.

What am I missing?

If anyone has a simple suggestion please let me know

Maybe looking at my old Spin code for SSD1963 can help:

One of the demos is for a 4.3" touchscreen instead of DVI output...

I have looked at that your assembly code. Do you have one in spin only??

Rayman

Sorry, I don't think I have spin only version...

Thanks

You probably know this, but you have to write an 0x2C before sending pixel data.
Looks like you have this at the end of your setwindow function, so as long as you call that, should be ok...

I will recheck it thanks.

I rechecked it the code is stone cold dead at this point. Screen initiation is good but the loop does not work. Would you have the time to run the code and see what you think?
Or anyone else who has this setup??

Thanks
