The first step is to find out what controller chip it has. In the manual there is a chapter on display panels. After SPI displays are the I2C displays. See if your chip is listed there. The only OLED I can see is this:- |

> OPTION RESET > OPTION SYSTEM I2C GP18,GP19 > OPTION LCDPANEL SSD1306I2C32 Error : Argument count > OPTION LCDPANEL SSD1306I2C32,P then get 2 real thin lines at the left side of the screen from top to buttom but i can draw a line 0,0,60,60 seems to work TENSTAR ROBOT 1,3 "OLED-displaymodule |

You might need the offset argument to get rid of the thin lines. I don't know, I've never used it and I haven't got one of those displays. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

This has a SH1106 and not a SSD1306 |

The OP doesn't say what version they are running. I made changes recently to support a much wider range of oled display controllers following help from another TBS member |

if wane upgrade do think the display whit a driver ili9341v whill work ? |

The ILI9341 is a different sort of display, using a SPI interface. It has a colour display. The Tenstar Robot 1.3" display uses the SH1106, with a I2C interface. It only has a single colour OLED display. The two displays are completely different. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I don't think it is supported but I can't say for sure |

The ILI9341 is supported in MMBasic. It's 320x240 and is, sort of, the "standard" SPI display. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

See Display Panels p57 in the V6.00.02 draft manual. A typical example is: OPTION SYSTEM SPI CLK-pin, MOSI-pin, MISO-pin eg OPTION SYSTEM SPI GP18, GP19, GP16 OPTION LCDPANEL ILI9341, Orientation, DC, RESET, CS(Chip Select) [,LED (Back Light brightness)] [,INVERT colours] '[] are optional. If not using brightness control connect the LED pin on the panel to 3.3V Older panels (v1.1) don't have transistor Q1 to drive the LEDs so must not be connected to a GP pin. Connect LED pin to 3.3V via a 100Ω to 220Ω resistor. eg OPTION LCDPANEL ILI9341, LANDSCAPE, GP15, GP14, GP13, GP20 'use any free pins for these Leave these touch pins disconnected T_IRQ, T_DO, T_DIN, T_CLK and connect T_CS to 3.3V (via a 10kΩ resistor would allow you to use touch in the future) You can save some SD card pins by sharing the SPI bus. First remove your current configuration with OPTION SDCARD DISABLE then OPTION SDCARD GP22 'SD_CS - chip select can be any free GP pin connect SD_CLK to GP18, SD_MOSI to GP19, SD_MISO to GP16 Also see page 64 Example SPI LCD Panel Configuration Edited 2025-06-11 10:09 by phil99 |

I know..I own one. But these seem to be different. Can you say that the "V" version will work? The upgrade adopts lPS full view panel, with good visual angle Edited 2025-06-11 15:36 by dddns |

This is interesting too, but it's driven with ST7796 "U" ..I don't know Edited 2025-06-11 15:52 by dddns |

No idea. Until someone tries one we won't know. :) As far as I know the *chip* specifications are the same, but that's only half the story. It's how it's used for this display. .

Hi tenij000, Below is a schematics, and associated OPTION settings where the PicoMite connects to a SPI LCD, and SPI SD card, and SPI TOUCH, using a ILI9341 panel. This is copied from the Game*Mite. Your hardware may connect different to different GPIO pins, but this should get you on your way. Note that the SPI pins (MISO/MOSI/SCLK) must be connected to a SPI pair on the PicoMite.   Thank Tom and Mick for designing this. Volhout PicomiteVGA PETSCII ROBOTS |

VCC, GND, SCK, MOSI and MISO are common to all three. They are three separate devices on the same SPI bus, but each has additional pins for it's own use. The display requires CS, RESET, DC and LED The SDcard requires SD_CS Touch requires T_CS and T_IRQ You can actually use any combination of the three devices by just connecting the required pins. If you don't want Touch then simply don't connect T_CS or T_IRQ and don't use OPTION TOUCH to configure it. Additionally, the SDcard can optionally use its own SPI bus or a "bitbanged" SPI that can use any available pins but has slightly lower performance. It may as well share the display SPI though as you only need to supply a pin for SD_CS. (Not this Mick for the above design. :) ) Edited 2025-06-11 18:18 by Mixtel90 Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
