Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

4 years ago, I wrote a file manager program for the CMM2. It's main purpose was to test the various image and audio formats that are supported by the CMM2. I had a few hours to spare so I decided to see how well it ran on the picoHDMI. The original was hard coded for 800x600 display so that was the first thing to fix. There are still a couple of tweaks needed. I decided to remove the mouse controls but that could be reintroduced if required. There are two changes I was not expecting. SEEK 0 on the CMM2 gets you to the start of a file. You need SEEK 1 on the pico. SEEK 0 throws an error. The pico drive A file system is case sensitive. The attached program should run on any display resolution and will adjust the number of columns automatically. If you don't like MODE 3 on the HDMI or VGA, edit line 29 I suggest renaming it to File Explorer to avoid confusion with Javavi's File Manager. helpTxt: DATA " FE v1.4" DATA " Use arrow keys to move between files, PgUp/PgDown to change pages" DATA " Home- Change to first file in root folder" DATA " End - select last file in current folder" DATA " Enter View Image and text files, PLAY audio files," DATA " load and RUN BAS files change folder" DATA " a/b - change drive" DATA " f - toggle font size" DATA " u - toggle colour" DATA " v - view file (including BAS files)" DATA " t - view as text" DATA " x - view as HEX" DATA " esc - quit viewing or playing."

Hello Jim, it runs on a lcdpanel 800x480 just as well. Thank you! |

Hi Jim, Thank you for File Explorer for pico. Some minor remarks: - In VGA Mode 1, the file highlighting (colouring) is only in the first column. - The help text banner is wider (800 ?), and does not scroll, so some parts are not visual on 640. Regards, Volhout PicomiteVGA PETSCII ROBOTS |

@Volhout I haven't any experience with the magic that produces the colour in VGA mode 1 but I am guessing that I need to start the text on a byte boundary. The program simply divides the pixels by 3. I will do some adjusting. The help banner is as short as I could make it. The main one is 'h' which shows the full help. You could try a smaller font. 'f' toggles between font 1 and 7 We were spoilt with the size of the screens on the CMM2. Jim VK7JH MMedit MMBasic Help |

Hi Jim, I remember in the old days we had: heX Help Edit View and the likes. But those days are gone now. We are in a new age... Volhout Edited 2024-09-27 17:44 by Volhout PicomiteVGA PETSCII ROBOTS |

This is looking more and more like CMM1.5 (or CMM1.75). :) Is this going to be the next programming challenge? Write a file explorer/manager for the Pico? ;) . Edited 2024-09-27 18:38 by Mixtel90 Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I have sorted out the strange colours/lack of colour I should read the manual more often. A fix tomorrow ... Jim VK7JH MMedit MMBasic Help |

It looks like it's a common project! I also started coding up a GUI file manager for the CMM2 a few years back. Just something to make copying folders and the like a bit easier, and maybe a front end for finding games. Now that I have my new CMM2's I think I'll dust it off and maybe give it a bit of spit and polish. |

I think I have fixed the colour in MODE 1 Using font 7 will be in monochrome, font 1 colour. I also fixed a couple of other bugs. FEpico.zip Jim VK7JH MMedit MMBasic Help |

To all interested in this. I'll be posting RC4 shortly - suggest you check it out Dim a%(5000) For i=0 To 5000:a%(i)=i:Next Input "File name: ",fname$ Edit File fname$ Print a%(222) Edited 2024-10-04 18:02 by matherp |

Peter, I not only checked, but already added and tested new EDIT FILE cmd to JAVAVI file manager. It works sure. It might be strange question for you, but I am simple user, not developer. So, what would happen if I would try edit larger file and there would be no warning-> there is no enough heap memmory? What would happen if user would be alowed edit that large file without any warning? What if user have no plans return to file manager, but just want edit that large program and then SAVE "xx" ? Isn`t this the same situation as after RUN $fname from program line, but instantly stopped? |

If you edit too large a program you should get an out of memory error. I need to check I've put that in all the relevant places. EDIT FILE will return to the program calling it like any other Basic command. If then you want to run the program you can code this in the file manager |

Then use a helper program, pass the file to be called with the Execute call. This helper program does nothing but call the edit of the big file. If necessary, you could reload the file manager after returning to this utility (and here you could save the configuration beforehand so that the same settings are loaded again). You have to be creative when programming with limited resources :-) Matthias |

Peter, While working on File manager and making improvements there and there I wanted make elegant way escape after INPUT, val$ has started and waits for user input. But what if user decides do not continue with INPUT or started INPUT dialog accidentally and wants escape? Elegant and usual way for user I would see by pressing ESC key. So if INPUT command would return and rise ERROR instantly after ESC key was pressed we could catch it and decide how to continue program. I see this as elegant enough way leave INPUT (not by entering multiple values until finished for example) I tried to look arround, read, play with interrupts and ON KEYS etc.. and finally gave up. I am reading and reading manual. I find so many tiny details I missed, but still it might be not enough of taht reading |

INPUT is a generic command that is used for files, the console and serial ports. ESC is a valid character for things like function keys or just binary data so can't work like you propose. If you want to do something like that you need to write a function in Basic to receive and echo characters one-by-one. That way you can interpret them as you wish including having a timeout if appropriate |

I was thinking that direction too but just needed to check if I did not missed something. Thank You. |
