SSD1963 hardware not working properly

Post by kabouras_33 »

Hello!
So I am trying to implement a nice LCD screen with touch(ssd1963) and I ordered one but until it arrives I decided to prepare the software .Unfortunately, when I try to load a bitmap from bitmap drawer fat it doesn't display anything. For the photo, I try to use the dragon for the glcd flowcode example and it works with other screens ex. ILI9341 (simulation and real).
Any pointers please? maybe i am missing something!!

Hello,

I've replicated the problem, started looking for you yesterday but then got pulled onto something else. I'll look again for you today.

Hello,

I'll try and have a look for you tomorrow, sorry for the delay. Does the code work ok on hardware or is it not working there either?

I have had a look for you a few times now and get so far into it and then get something else come in that needs attention. I'm out the office tomorrow so hopefully a good oppertunity to have a good look for you.

Hello again...so I tested the hardware and unfortunately no go...
the screen is this one https://www.ebay.com/itm/7-inch-800x480 ... 2749.l2649
and I have my project attached...pretty simple really pic18f67j50 with 18432000 external crystal. Flashing led and try to print hello.
Led is flashing but tft turns black when I power on and stays black.
Connections are 3x checked
TFT - pic
data port - D0-D7
CS - C0
WR - C1
RD - C2
RS - C3
REST - C4
5V - 5V (BACKLIGHT)
3V3 - 3V3 from a regulated power supply

Any help would be much appreciated

Hi karoubas!

Don´t know if it is the same as in the other display. But you need to give the display some more info (setting) I change a little in your program, maybe it can give you some help. now it work in simulation but slow, maybe a "heavy display" need a fast processor. But look good, and expensive :lol:

Could be.

Dear jgu1,
Thank you very much for your response and effort but unfortunately, after loading your code the result is still the same....black screen...

Have you tried with 'display method' set to 'bitmap' (not 'point cloud')?
Certainly works (only) with this in simulation mode.

Hopefully some luck..

Sorry, but don't have one of the displays to try - so can only suggest the usual 1s blinkie, wiring and the like.I

Give us a pointer to the exact type of display you are using - there are lots using the same controller....

I don't think the MCU is the problem - speed / memory should be sufficient so that leads to:

1) Hardware error. Something in the setup doesn't work. So display is faulty / wiring is faulty / MCU is faulty.
(Note we can probably rule out 1 and 3...)
or
2) Software error - something in the timing or setup doesn't work / the component doesn't work / the MCU isn't communicating properly (WDT issues seem common)

I would try and get the display working first (forget touch and SD) then build on that..

Note - I've been 'playing' with some ST7789 displays and managed to get some displays running and others not - and I suspect a 'subtle' difference in startup requirements between chip revisions - but stumped at the moment :-(

Dear Martin on previous posts i have informed on all the informations i have including links to the screen as well as a test flowcode...i am just trying to make the screen go only for now...

But thanks again for your guidance!!!
Anyone from flowcode team care to give some support?

I tried with internal OSC w/pll at 40Mhz on the dspic33fj256gp710a and reached 500000 baudrate :shock: :shock: nice find but the screen still doesn't work...sometimes when I change configurations I can see flashing constantly other times I can see white noise with a few colour lines....bummer....I am in a dead-end I do not where to look

Well after more searching i came to the conclusion that maybe flowcode init uses the pmp of the pic32....so since there is nothing else to try with the pics i have, i ll wait until the pic32mx764f128h arrives and i try again covid 19 delays :twisted: :twisted: .
Anyway thanks for the support...

Hello,

I had a dig for my 1963 display but couldn't lay my hands on it. I'll keep looking to see if I can help.

PIC32 shouldnt be required.

Thanks Benj,
I hope you can have the time because i was pretty sure that this component works before i order and plan my new release (i shouldn't before i actually tested) and now nothing....
I will look forward to your reply and just keep trying...
