Forum Index : Microcontroller and PC projects : picoMite VGA 16 colours? Problems...

Hello again, as the title says I am having problems to display all 16 colours with the picoMite VGA. RGB(white) is the same as RGB(grey) and RGB(gold) is the same as RGB(yellow) as well as RGB(salmon) and so on... But in the manual on page 52, it is stated that 16 colours are possible in MODE 2. What am I doing wrong? The multiturn potentiometer and the jumper on the PCB set to "RGB" does not help in any way. Colours do work, blue is blue, red is red, green is green... Maybe I am misinterpreting something? Manual not up-to-date? It says: "The PicoMiteVGA version supports 2 “colours” in monochrome mode and 16 in colour mode."

Any luck with this program of Peter's? Are you sure that both of the green pins are connected? Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Mick... Awkward but... I found the problem. The jumper was set wrong. And I thought I checked it   Thank you for pointing me to Peters testprogram! Greetings Daniel |

The simplest way to get all 16 colours is:- Picomite Monitor Red____________220R_______________Red Green High_____330R_______ |________Green Green Low______680R______| Blue___________220R_______________Blue (Variable character spacing makes alignment tricky!) Edited 2022-04-21 07:58 by phil99 |

I just took the original wiring with the jumper and the multiturn potentiometer... |

In order to at least make a meaningful contribution, I converted an image into the color palette of the picoMiteVGA with Photoshop. I'm amazed at what you can do with just 16 colors! On the monitor it looks the same :) With the saved colour palette I can now convert any image pretty quickly. If you use Photoshop, here is the picoMiteVGA Colour Palette and you can do the same: colourPattern.zip Our dog Tali:  Edited 2022-04-21 09:40 by Amnesie |

Beer is good.  Smoke makes things work. When the smoke gets out, it stops! |

Glad that's sorted, Daniel. :) I thought it must be something silly as that board has been pretty well tested now. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
