Hi all, I haven't seen any comments/posts on the CMM2 article in Silicon Chip (pp88). I typed it in and checked it over and over but I still cannot get it to push a ball around the screen; all I get is a same-size "bar"bounce off the screen extremities. I tried a few mods, without success. Did anyone get this working? Regards, Bob Devries Bob Devries Dalby, QLD, Australia |

Maybe zip up the code and post it for those who don't have SC but may see the problem. John |

I guess it's something like a typo. John |

This is the program, perhaps you can copy and paste it: BOX 0, 0, 800, 600, 1, RGB(yellow), RGB(black) x = 400 y = 300 dx = 1 dy = 1 DO CIRCLE x, y, 30, 2, ,0, RGB(red) x = x + dx IF x = 31 OR x = 767 THEN dx = dx * -1 y = y + dy IF y = 31 OR y = 567 THEN dy = dy * -1 PAUSE 2 LOOP For people who don't have access to the SC article; this program will cause a red ball to zoom around the screen bouncing off the walls. It is not particularly complex, nor useful, but it does provide a simple demo of graphics on the CMM2. Geoff Geoff Graham - http://geoffg.net |

This little demo just showed I have a issue with the video output of my CMM2. The demo draws the outside boarder on the screen and on my system it has 1 pixel cut off on the right side. I have changed the aspect ration of the screen to 1 to 1 and it is just not able to display the last colum of pixels. I edited the demo with everything 1 pixle less and it works but This is not cool. I have gone back to several other demos and it is differently as issue with my system. It is like the viewing screen onto the output is 1 pixle to the left. Does anyone know what could be causeing this. I have fully assembled system form micromite.org. I am attached to a VGA monitor. EDIT: I just attached it to 2 other displays and one had just a half a pixel cut off and the second one had 1 and 1/2 pixels cut off. and they are ghosting an inverted copy of the 2 pixel columns just off-screen It is like the first 2 pixel columns for the left side are being displayed on the right a few pixels past the screen area.

Have you tried an auto calibrate on your monitor? My display was wonky at first but I pulled up the on screen display for my monitor and hit the auto calibrate button and it fixed it. |

Most monitors have a "auto adjust" button or menu item which syncs the monitor to the source. Try and find it and use it. Normally solves this sort of issue |

I have not used auto ajust in a long time and yes that is all it was. The problem with my monitor is that it is only accessible from on undocumented long-press on a button used for backing out of menus (ASUS) had to find a PDF of the damn manual to find it. NOT very intuitive and thanks all for prompt help as always. They call me Shai-Hulud (The maker) |
