G'day Peter,
This is probably more a niggle than a problem:

With ILI9488 or ST7789S in Landscape with LCDPANEL CONSOLE 1,,,,NOSCROLL

List Pins scrolls of the screen leaving "Press any key to continue" at the top line of a blank LCD, regardless of starting position.

List Commands / List functions works correctly.

> option list
PicoMite MMBasic RP2350A V6.03.00RC25
OPTION SYSTEM SPI GP18,GP19,GP16
OPTION FLASH SIZE 4194304
OPTION COLOURCODE ON
OPTION CPUSPEED (KHz) 200000
OPTION LCDPANEL CONSOLE ,,,,,NOSCROLL
OPTION DISPLAY 26, 60
OPTION LCDPANEL ILI9488, LANDSCAPE,GP14,GP13,GP12
>

Edit: Also noticed that if the prompt is on the last line of the LCD, as soon as a character is entered it clears the LCD and starts on a new screen. This may be the culprit.

Regards, Lyle.

The NOSCROLL parameter is what causes the screen to clear. If you get rid of that, LIST PINS works as long as none of the lines is longer than your screen width (in my case 40 characters or 60 in your case)

G'day,
Toml_12953, Depending on the LCD panel type and orientation, the use of NOSCROLL is somewhat necessary, strangely in this case removing it causes a further problem.

Peter, Further to previous post, removing NOSCROLL stops the LCD at the bottom line of a full screen and no further text is displayed, the terminal console will continue to slowly work but no further text on the LCD. Older versions would continue to write on the bottom line instead, sometimes with a white out of the rest of the LCD.

Using CLS twice will clear the LCD and allow another screen full.

Regards, Lyle.

List pins is just a Basic program embedded in the firmware.

This is the code

Dim _q%
For _q%=0 To MM.Info(max gp)
Print "GP"+Str$(_q%), MM.Info(pinno "GP"+Str$(_q%)),MM.Info(pin MM.Info(pinno "GP"+Str$(_q%)))""
If _q% Mod (MM.HEIGHT-2)=0 And _q%<>0 Then
Print "Press any key to continue";
Do
Loop Until Inkey$<>""
Print
EndIf
Next
Erase _q%

If you can fix it so it works both for scroll and no-scroll then I'll update the firmware

Hi Peter,
I cannot fault the logic behind the list pins program and if I load it as a program and run it it works exactly as it should.

With no real understanding of the interactions with other parts of the system I am the last person who should be commenting on this.

My rather naive thinking is:

When RUN is executed the screen is cleared, and running list pins as a program works fine, so does it just need a CLS?
Considering List Pins will overload most screens anyway, would adding a CLS at the start break anything else?

Dim _q%
CLS
For _q%=0 To MM.Info(max gp)
Print "GP"+Str$(_q%), MM.Info(pinno "GP"+Str$(_q%)),MM.Info(pin MM.Info(pinno "GP"+Str$(_q%)))""
If _q% Mod (MM.HEIGHT-2)=0 And _q%<>0 Then
Print "Press any key to continue";
Do
Loop Until Inkey$<>""
Print
EndIf
Next
Erase _q%

Regards, Lyle.

Is there any hope we could get LIST PINS to switch to font 7 (if MM.WIDTH is 40), then do the list, then change back to font 1? This would allow all the lines to be listed without scrolling the beginning off the screen for us LCD users.

Alternatively, is there a list of tokens somewhere? I looked through the manual but didn't see one. If I have that list, I can modify the source code for my own machine as I did when I added OPTION TAB 10.

Ok, I tried another original Pico2 - it works with PicoMiteRP2350V6.03.00RC25 on my PicoCalc. The "old one" doesn't!

My "old one" was an absolut new, original Pico2. What the f...!!!

Frank,

do the CPU chips on the boards have the same stepping (A2 or A4)?

@ville56:

I won't be able to check that until the next few days—I don't have the old Pico2 with me right now.

@homa:

Thank you very much for the link! I'll have to update the BIOS to version 1.6 when I get a chance...

Is there a chance that Option screen keyboard will be available for SSD1963? It might even be good for 480x320 LCDs.

No, to work nicely it relies on multi-touch and a decent sized screen

I only had the chance to test it with GUI CURSOR LINK MOUSE and that works very nice on console.

I actually got around to checking out the two Pico2s today after all.
Both chips have exactly the same markings:

RP2350A0A2 25
PAKV44.00 24

There is an inductor feeding the 1.1V rail on the Pico-2 (check the datasheet for location). If you have a scope what would be very interesting is to see the voltage on the processor side of that inductor as the PicoCalc turns on standalone and then compare it to plugging in the microusb. Given that the only relevant difference between RC22 and RC23 is that RC23 enables the FPU my strong suspicion is that the FPU isn't starting up properly on the original board when powered by the PicoCalc but is when powered by the USB. The difference between the boards could be any marginal difference in component tolerances or quality

Peter,

Quick question. Rp2040 with ili9341 lcd.sPI.
If I wat to work with high color depth files, is there any faster way then loading them from the A drive?
Tiles are roughly 20 in 30*30 size. Memory wise they could fit in flash slot at 2 byte per pixel, but ther is no methode to SPI them to the glass, right .. that is faster than LOAD IMAGE from A drive.???

Hello Volhout,

I tried that with Blit slots using Blit read/load/write which is very fast like Framebuffer copy

G'day,
Toml_12953, Whilst there are probably better ways of doing this, these all seem to work:

To solve the NOSCROLL problem, store in LIBRARY:

Sub LISTPINS
CLS
List Pins
End Sub

To change to font 7, store in LIBRARY:

Sub LISTPINS
Font 7
List Pins
Font 1
End Sub

Also a modification to the code Peter supplied to ensure no more than 40 chars wide:

Sub LISTPINS
Local _q%
CLS ' Optional, use with NoScroll
For _q%=0 To MM.Info(max gp)
Print "GP"+Str$(_q%)+Choice(_q%<10," "," ");
Print LEFT$(Str$(MM.Info(pinno "GP"+Str$(_q%)))+" ",3);
Print LEFT$(MM.Info(pin MM.Info(pinno "GP"+Str$(_q%))),32)
If _q% Mod (MM.HEIGHT-2)=0 And _q%<>0 Then
Print "Press any key to continue";
Do
Loop Until Inkey$<>""
Print
EndIf
Next
End Sub

Probably not the correct thread to discuss this subject so we should probably open a new one for anything further.

Peter, As previously mentioned, if anything is typed with the cursor on the bottom line of the LCD with NOSCROLL enabled it clears the LCD and starts a new page, is this the expected behaviour?
Michael (twofingers) earlier in this thread also mentions INPUT being used on the bottom line creates similar behaviour, testing shows this also to be the case.

Yes: that is what no scroll does, when it runs out of screen space it clears and starts again at the top because it can't SCROLL.

The LIST PINS issue is fixed and will be in the release
