Hello, yesterday I build the VGA PicoMite from the Silicon Chip Kit. So there is an SD-Card, VGA and PS/2 connector. Everything works well. As early microcomputers like the TRS-80 this setup does not have a RTC on board and I had to set the time$ and date$ manually. I could add an RTC module, but I want to keep the PicoMite as simple as possible. The idea is to autorun some code to set time$ and date$ at boot. The only mechanism I found in the handbook was to use some mm.startup sub which has to be in the flash somewhere when the pico boots. I wrote 2 files: autorun.bas and mmstartup.bas and stored them on the sd-card. In autorun.bas are all commands I want to execute at startup and in mmstartup.bas is the definition of sub mm.startup which calls autorun.bas. I placed the mmstartup.bas into flash 1 to load it at the end of the day with a flash load 1 and then switching off the VGA PicoMite. At the next boot the Sub will be in memory and found by the firmware. If someone knows a better way (like CMM2) I would be glad to hear! I think taking care of some mm.startup sub every time I switch off the picomite is not very elegant. May be I simply don't understand how the "autostart" should work normally?!

I was under the impression that you can't specify a FILENAME unless you were using an SDCARD with actual files on it, not flash. With the Flash option, you would need to use Flash Chain X where X is the FLASH SLOT number where your program code is stored. Correct me if I'm wrong... this is all still rather new. Note: I've also had a situation where SUB MM.STARTUP didn't always seem to run (at least that was my perception a few weeks back but that might have been a coding error on my part -- a common occurance) Edited 2022-09-22 23:18 by pwillard |

To run a PicoMite program automatically from flash it's very easy. Write your program. Use FLASH SAVE n to store it into flash slot n. Run OPTION AUTORUN n where n is the number of the flash slot. That's it. On boot the program in flash slot n will run. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

thank you! just a few seconds before you wrote it i found it this way: pdfgrep -in auto PicoMiteVGA_User_Manual.pdf | grep -i run 14:In addition the command OPTION AUTORUN can be used to specify a flash program location to be set 14:location and in that case MMBasic will automatically load and run the program that is in the program memory. 47: MM.INFO$(AUTORUN) Returns the setting of the OPTION AUTORUN command 48: will run. “option” can be one of AUTORUN, BASE, BREAK, 49:OPTION AUTORUN ON 49: MMBasic to automatically run a program on power up or 49:OPTION AUTORUN n ON will cause the the current program to be run. 49:OPTION AUTORUN OFF 49: OFF will disable the autorun option and is the default for a new program. 53:AUTOSAVE CRUNCH This mode is terminated by entering Control-Z or F1 which will then cause 57: If OPTION AUTORUN has been set the program in the specified flash 61: One of these flash memory locations can be automatically loaded and run 61: when power is applied using the OPTION AUTORUN n command. 85: stopped running) the PicoMiteVGA will be automatically restarted and the 85: false (i.e. 0). Note that OPTION AUTORUN must be specified for the -andreas |

Yes, I'm using the sd-card as filestore. My current solution is based on "autorun.bas" on sd-card and the SUB mm.startup in flash 1. After OPTION AUTORUN 1 the mm.startup sub will call the autorun.bas. This way I have only to think about the content of "autorun.bas". I can switch on and off without thinking about the current state of the system - it will always call autorun.bas. The only thing I have to prevent is to change flash 1 which is the caller. -andreas |
