800x480/2 = 192000 (188K) too much for a RP2040 but might just work on a RP2350

Thanks for the promt answer. That destroys half of the usecase for my project but once the chinese will offer a board with at least all 30 GPs lined out, it could be replaced. I should have investigated before..

When running ssd1963 in 16-bit mode, "option lcd320 on" works and a framebuffer can be created. Issuing an "option lcd320 off" will work but an error "invalid option" occurs.
When running the display in 8-bit mode, "option lcd320 on" throws the error "Only available on ssd1963,....". Is it really not possible to run this option in 8-bit setup?

V6.00.00RC4

PicoMiteRP2040V6.00.00RC4.zip

PicoMiteRP2350V6.00.00RC4.zip

Fixes various bugs in HDMI edit colouring

New command

EDIT FILE fname$

This is a command that can be called in a program allowing you to edit a disk file without affecting the running program. Obviously, the editor has to share memory with the running program so if you are using most of the memory before calling the editor then only a very small file could be edited. This command is designed to allow things like a user written file manager to be better developed.

Test program

Dim a%(5000)
For i=0 To 5000:a%(i)=i:Next
Input "File name: ",fname$
Edit File fname$
Print a%(222)

When running the display in 8-bit mode, "option lcd320 on" throws the error "Only available on ssd1963,....". Is it really not possible to run this option in 8-bit setup?

Not at the moment because I haven't coded it. All of these sorts of features take big chunks of special case code and this one isn't on the horizon since no-one seems to have used the 16-bit version before

Thanks again for your answer as it encourages me to finish my project. From my point of view this display is the only one which makes it seriously possible to use it as main display even for editing code. I am building a stand alone development/educational plattform and it would be essential to have some native GPs free..

Thanks for the RC4 Peter,
The font bug in LOAD is only partially fixed. In case of an error, e.g. LOAD without quotes, the error message appears again in the larger font.
I had another BUG (RC3) with mp3 playback. But I could not reproduce it reliably. The sound file is completely muffled and plays very quietly (and slowly?).
I'll try to reproduce it and see if it's still there in RC4.

Some things you have to live with. The font reverts to the current default after an error. This is necessary as, for example, if you are using the large number only font (6) then there are no alpha characters to display the error. Reverting to the default guarantees the error will be seen

OK.

Here is the mp3 sound bug (reproducible!), in the ZIP an audio sample and the program test_soundbug.bas and the wav file from the program BLOCKS.
You can then take any mp3 file you have, no matter which one of my mp3s the error always occurs on playback.
Good luck.

I am using the standard 2350 firmware RC4 (ie nonHDMI/nonUSB) on a RPI Pico2.
Connecting a 5” SSD1963 as per Pico manual (DB0-DB7 to GP0-GP7, etc).
Known working display as it works on 44pin MM (configured for 5V operation, with SSD backlight control, on 8080 interface).

I can successfully control the backlight intensity with the BACKLIGHT xx command which confirms all signals and DB lines are correctly connected.
BUT the display remains ‘black’ and it is not possible to see anything on the display (apart from the backlight ‘bleed’). Trying GUI TEST LCDPANEL as well as CLS RGB(colour_name)

I have tried OPTION LCDPANEL SSD1963_5,L and also _5A (and 7 and 7A just in case this made a difference!) but no matter what I try the display remains ‘blank’.

Is anyone able to test RC4 with an SSD display to confirm if they’re able to see something on the display.

I will try a 7” and 9” sometime in the coming days, but really want the 5” to work for a specific project.

Any confirmation (or suggestions) would be greatly appreciated….

Can't test the RP2350 but RP2040 RC4 definitely works on SSD1963. Suggest you get that working first and then substitute.
How are you powering the display 5" is the hardest to power and you may be overloading the 3.3V rail

Good call to drop in a 2040 as you have been able to confirm that it works.

Powering as a 5V unit from a 3A RPi PSU (common GND with USB to laptop running TeraTerm).
3.3v power rail on SSD reads 3.28v so happy with that.

Let me try your suggestion of a 2040 with RC4 tomorrow…..

Still no joy here with either a 2050 or 2350 connected to known working SSD displays using RC4 (but note I have not tried an SSD on any previous versions of firmware)..

Is the following connection guide 100% correct?

matherp said V6.00.00RC4

Where can a user or program in the PicoMite MMBasic environment find out on which stone it is running (from RP2040 RP2350A RP2350B)?

can display in the device name ?

PicoMite [RP2350A] MMBasic Version 6.00.00RC4

or can add a command to get this information ?

MM.INFO$(CPU)
