Hello,

on amazon I found this: RP2040-LCD-0.96-M

Does anyone know whether it runs with PicoMite?

On first glance I think so. The display uses GP8, GP9, GP10, GP11, GP12, GP25 so no PS2 keyboard. No guarantee for any speed over 133MHz though!

Probably this.
It seems to be an SPI display, uses GP25 for the BL. Is GP25 OK to use once you do OPTION HEATBEAT OFF ?

Should be able to, yes. There is no LED on that board so there's no other hardware to mess the pin up.

I can't see anything that would prevent MMBasic from running on it. However:

The display is ST7735S, which has MMBasic support.

There is no heartbeat LED. GP25 is connected to the backlight.

The only speed specified is 133MHz. It may or may not overclock.

If you are willing to take the risk then go ahead. :)
Pi Hut list it for 15.10 UKP

160x80 isn't exactly a gaming display, Stan. :) Good for coloured text and simple animations though.

Hello,

the RP2040-LCD-0.96-M is Picomite compatible

PicoMite MMBasic Version 5.07.07

OPTION COLOURCODE ON
OPTION HEARTBEAT OFF
OPTION DISPLAY 50, 100

(this is out of experimentation, if someone knows a better setup for system spi and lcdpanel I would be very glad to hear!)

Brightness can be tuned by "BACKLIGHT N" N=[0..100]. In the picture backlight is 40%.

Great to see it working. :)

You've no choice of IO pins for either system SPI or the display IO pins (including GP25) as they are all hard-wired on the module.

Hello Mick,

yes the pins on the board are fixed, but there is one degree of freedom for the 4th parameter of the OPTION LCDPANEL:

OPTION LCDPANEL ST7735S, LANDSCAPE,GP8,GP0,GP9,GP25

I took GP0 to write anything, but I'm loosing a gp port this way. Thank you by the way for the display type tip - it has shortened my experiments considerably.
