Not working with Picocalc. I think this can done by an other keyboard BIOS maybe in the future.

Manual

Quote 8 and 9 inch Displays
The controller configuration SSD1963_8 has only been tested with the 8 and 9 inch displays made by EastRising (available at www.buydisplay.com). These must be purchased as a TFT LCD panel with 8080 interface, 800x480 pixel LCD, SSD1963 display controller and XPT2046 touch controller. Note that the EastRising panels use a non-standard interface connector pin-out so you will need to refer to their data sheets when connecting these to the Raspberry Pi Pico. A suitable adapter to convert to the standard 40-pin connection can be purchased from: https://www.rictech.nz/micromite-products

16-bit Parallel LCD Panels

The rictech product appears to no-longer be available

PM grogster, he may have some left, alternatively he may let you have the gerbers. It is a trivial circuit to reproduce in any case.

Oh, I understand that, it was more about the link in the manual. We recently had similar with Font Tweak, etc.

when you say "not working...", what exactly do you mean, is not working? I have installed it today on my PicoCalc and to me it seems, everything is ok. Have i overseen something? Please let me know. Thanks.

best regards,

Xian

Keydown(n) is returning always 0 even if I press any button on Picocalc.
Maybe some options is not correct?

On page 192 of the manual it says:

Quote Return the decimal ASCII value of the keyboard key that is currently held
down or zero if no key is down.This function applies to USB keyboards and
PS2 keyboards

As you can see, KEYDOWN only applies to USB and PS2 keyboards.

How can I get rid of the NOSCROLL in the OPTION CONSOLE LCDPANEL?

Originally, the option looked like this:

OPTION LCDPANEL CONSOLE ,,FF00

but I changed it and now it looks like this:

OPTION LCDPANEL CONSOLE ,,,,,NOSCROLL

I'm trying to get it back to its original values but get an invalid option error.

I'm using the non-VGA, non-HDMI version on a PicoCalc.

Thanks. I tried that and I get an option error. The syntax in the manual doesn't seem to match what is actually in the option list. I can get the FF00 back by setting default colors but I can't get rid of NOSCROLL.

I end up with

OPTION LCDPANEL CONSOLE ,, FF00,,,NOSCROLL

See all the commas? The syntax in the manual doesn't allow that many.

You can't comma out the first parameter. Same for all MMBasic commands

OK, thanks. I still can't get rid of the NOSCROLL, though. I tried leaving the last parameter empty and I tried making it a null string "" but neither works.

Yes. As I said, I tried that. I can't seem to get rid of NOSCROLL on a PicoCalc except by reflashing the firmware. If there's a syntax that will do it, I'd like to see it.

I don't even know where the FF00 comes from. I know it's added when I change the default colors to green on black but I don't see a correlation between the two. I would think if FF00 was the foreground and background that it would mean white (FF) on black (00)

G'day Toml,
This may be something specific to the PicoCalc.
Just tried both PicoMite MMBasic RP2350A V6.02.01 and PicoMite MMBasic RP2040 V6.02.01 with an ILI9488 LCD with the following results:

> Option lcdpanel console 1,&hff00,,,noscroll - sets parameters (&hff00 is green)
OPTION LIST = OPTION LCDPANEL CONSOLE ,, FF00,,,NOSCROLL

> Option lcdpanel console - resets all parameters
OPTION LIST = OPTION LCDPANEL CONSOLE

> Option lcdpanel noconsole - disables console

So &hFF00 is foreground colour green, background colour is default so not shown. colour is &hRRGGBB in hex.

Hope this helps, I don't have a PicoCalc to test.

Regards,
Lyle.

Great! Thanks. At least that explains how to enter colors. I still don't understand why FF00 (green) is the third paramater. The manual says

OPTION LCDPANEL CONSOLE [font [, fc [, bc [, blight]]] [,NOSCROLL]

so it seems to me that the foreground color should be the second parameter and, as Peter says, the first parameter must always be entered so I'd think you'd need

OPTION LCDPANEL CONSOLE 1, &HFF00

at a minimum to set the foreground color green and to set the foreground to green and the background to red,

OPTION LCDPANEL CONSOLE 1, &HFF00, &HFF0000

In any case, I'm still looking for an example that turns off NOSCROLL.

It appears that you can turn off the functionality of NOSCROLL but the word NOSCROLL still appears in the OPTION LIST.

OPTION LCDPANEL NOCONSOLE
OPTION LCDPANEL 1,RGB(green),RGB(BLACK)
assuming you are using ILI9488P in portrait mode. But if PicoCalc then ST7365P is better

Following the above, I get a message, "Display already configured"
