dddns said My new toy:

PicoMite MMBasic USB RP2350B Edition V6.01.00RC2
OPTION SERIAL CONSOLE COM1,GP28,GP29
OPTION SYSTEM SPI GP22,GP23,GP20
OPTION FLASH SIZE 16777216
OPTION COLOURCODE ON
OPTION KEYBOARD US
OPTION PICO OFF
OPTION CPUSPEED (KHz) 378000
OPTION LCDPANEL CONSOLE
OPTION DISPLAY 40, 100
OPTION LCDPANEL SSD1963_7_16, LANDSCAPE,,,NORESET
OPTION TOUCH GP21,GP19
GUI CALIBRATE 1, 148, 261, 2095, 1366
OPTION SDCARD GP24, GP25, GP26, GP27
OPTION F9 flash run 1
OPTION PSRAM PIN GP47

When storing the options to disk(tried both) and reset them and reload the file it errors with "Display not configured". Having no display configured then save/reload works.

After Option display console 1 it freezes and need clear_flash

Framebuffer L and F don't work for me. It only shows a small section at the wrong place

Many thanks for the fixes!

Option lcdpanel console 1 works as well as saving the image and to calibrate the touch.

What hasn't changed is the scrambled picture with framebuffer. Some graphics are drawn error free other are not shown, only half or only a small tile.
But as I might be the only one using this there is no hurry or need..

p.s. there is no difference between with PSRAM enabled or not. It runs with framebuffer without error and leaves 40k free heap what I think is too much

Please provide an example program that demonstrates the issue. I created a program with both framebuffer and layerbuffer and tested both copy and merge with no issues

Good morning,

I'm not able to provide a simple test program.
Please download this save it to a subdir on A: or B: , change into it and comment out the first two lines:

Option explicit
'Option console none

Dim integer vid_opt = 0 ': MODE 1 : If MM.HRES > 1000 Or MM.Info(heap) > 10^6 Then vid_opt = 1

Dim vid_mode '= 1 : MODE vid_mode

I've prepared it already for using it on SSD1963

Thanks that you care for that issue!

There is something else I observed:
For Mode 1 I use tiling. In some scaling values, printing with Text command will destroy tiling in a small area. This happens especially with Font 1.
In these situations x/y is somewhere but not on a exact tiling position character wise.

edit: The first drawing is so scrabled you can't read the menu. Please press home/end to change to the next one. The third starts looking better

Sorry, but in that case I can't look at it. I've tested with a simple program and confirmed that the correct amount of memory is being allocated safely (187.5K each). I've checked FRAMEBUFFER COPY and FRAMEBUFFER MERGE and they both work perfectly.
I can't be expected to dig into a complex program to discover what is either incorrect in the program or the firmware.

No problem. I didn't expect that you look into the code but more that you have a picture how it looks like.

If an object is scaled down to middle of screen it starts displaying correct.
I've just tested Lcd320 on and that looks much better.
320 mode works better that in the versions before but is not correctly centered

A last non technical comment:

Using Picomite with a 7" SSD1963 as local screen is such an amazing experience and stand-alone computer feeling, I can't find words.

I would like to thank you for that!

Maybe it has something to do with Fonts, I don't know.
In the FM application I need to correct the printing position for Font 2,3,5,7 with -1 that that last column is shown on the local screen while tty always fits

edit:as well for a ILI9341

I am applying approx. 5V from battery (via a step-up converter) to VSYS. for the test above, I used a USB dongle that just provides data and ground (no power).

Must be something h/w related. Faulty Pico2? or something in your design? Results are the same with heartbeat on or off.
