Hi all.  Ended up with a day to spare today, so I spent it playing with a PM VGA, working towards porting the last of my PICAXE code over to this. Everything is going well, but I have one question about the crafty way you can use colour in mode 1 on the PM VGA. How do you clear the screen once you have put colour on it via the TILE command? CLS clears all text, but leaves all the TILE colours there. CLS RGB(BLACK) also does not remove the colours I have added. Pressing F4 to enter the editor DOES, so that is how I am getting rid of it for now, but is there a command I can use to essentially wipe all the colour added via the TILE command in mode 1? The long way around, is to keep track of what colours I have used and where, and manually remove them one-by-one in code, but that will get tedious very quickly, so if there is a faster method, I'd love to know what it is. Thanks chums. EDIT: I guess it would be dead-easy to write a simple sub that just makes all tiles black, then returns, so I think I will just do it that way. I can't see anything specific in the PM VGA manual to suggest there is a command that I am not seeing, so.... EDIT: No, that does not work either - it makes the screen PERMANENTLY blank, and you can't see ANYTHING then till you use F4 for the editor again. This is what I tried to do: Sub WIPE Local Row For Row=0 to 29 TILE 0,Row,RGB(White),RGB(Black),40,1 Next Row CLS End Sub Adding the likes of COLOUR WHITE to the sub at the end, or just typing it in at the command prompt and pressing ENTER after this sub runs does not give me back anything, so a bit stuck on this one... EDIT: Keep foreground white, make background black, wipe all tiles, then CLS. See edited code box above. This is working fine. Problem solved.

In my PicoGAME test program I used Mode 1 Font 3 CLS to clear the screen between each page. That works for what I needed. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Yes, that is even better and more simple! Thanks. Smoke makes things work. When the smoke gets out, it stops! |

@Peter, I guess this is probably a no-go, but I think I ask anyway. The editor supports function keys (i.e. F1...F5). In the option settings you can program function key F6. Can F6 be used inside the editor in some way? i.e. F6 is programmed TILE 0,0,rgb(blue),rgb(white),40,30 + <CR> I guess you see the purpose... Volhout PicomiteVGA PETSCII ROBOTS |
