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! Edited 2023-05-29 19:55 by Mixtel90 Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

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 ? Latest F4 Latest H7 |

Should be able to, yes. There is no LED on that board so there's no other hardware to mess the pin up. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Looks interesting but does it work with mmbasic indeed? and cost? |

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 Edited 2023-05-30 04:28 by Mixtel90 Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Let us know how it goes @andreas It looks nice but someone got to test with mmbasic if it isn't plug n play. not me sorry but if ok I may get one. Looks neat but in reality ??? the display 80 pixels |

160x80 isn't exactly a gaming display, Stan. :) Good for coloured text and simple animations though. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

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. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

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. -andreas Edited 2023-06-06 13:59 by andreas |
