Are you relying on the screen to start up blank? You can't use CLS on the console as it's a graphics command, Try: print chr$(27);"[2J" to clear the console screen. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Hi Mick, simple code but only power up autorun prob. code "works" when a key pressed. if autorun off then just uk kb message until I reflash from win mmedit pc or mmcc or type on pico usb kb.

The USB message would normally be sent to the console. If you are using a VGA monitor then I wouldn't expect to see this unless you were using OPTION LCDPANEL CONSOLE. Try entering OPTION LCDPANEL NOCONSOLE at the prompt and see if that works. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

hi stanleyella, the default out-of-the-box configuration for all picomite VGA variants (both USB and PS/2) is for both keyboard/VGA and serial console to be active. this corresponds to OPTION LCDPANEL CONSOLE being set. this is necessary so that the VGA picomites can be initially turned on and will operate as a standalone boot-to-basic computer, just like it was 1985 again. at the same time, you can still attach via a serial console (or serial over USB) and operate the picomite VGA via a terminal emulator such as TeraTerm or GFXterm if you wish to. in this default configuration mmbasic sends text to the VGA screen, as well as to the (serial) console. and mmbasic also responds to both an attached keyboard as well as data received from a console - just like what happens when you plug two keyboards or mouses into a PC. with the picomite VGA+USB, whenever a USB keyboard is connected or unplugged mmbasic generates a message, as you have seen. in the default configuration this message is displayed on both the VGA screen as well as being sent to the serial console. it could be argued that these keyboard attach/detach messages are diagnostic messages that should be removed from mmbasic, but if i were to ask Peter about this it would simply ensure that said messages would be retained in perpetuity. the instructions Mixtel90 have given you (setting OPTION LCDPANEL NOCONSOLE) severs the link to the VGA screen; PRINT statements will no longer be displayed on the VGA screen, error messages will no longer be displayed on the VGA screen, keypresses (from keyboard or serial) will no longer be echoed to the VGA screen. when configured in this way, the only way of sensibly operating the picomite and writing BASIC programs on it is via a tethered PC running a terminal emulator of some sort (MMedit is essentially a terminal emulator, but with quite a few added extras). note that OPTION LCDPANEL ... in this instance does not specifically refer to just an "LCD panel", it refers to any screen attached directly to a picomite, be it a tiny LCD panel running over an I2C interface, right up to a full-sized VGA monitor. the word LCDPANEL is a carryover from the early days of the picomite and retained for reasons of <warm fuzzy feelings>. cheers, rob :-) Edited 2024-03-20 11:34 by robert.rozee |

The messages should be suppressed while running a program - just haven't implemented this yet. I'm intending to do a full release at the weekend which will include this. |

option list does not show option lcdpanel console status, or I would have known. Yes, it would be obvious... to many people but I'm new to "a console" and inbuilt editor and a stand alone basic computer. You still need a pc to flash firmware and use xmodem to save files. If I code a non vga pico not using a lcd display then a pc needed for editing code and mmedit is easier than inbuilt editor and using xmodem (which I've never used) and sending files to pc and sending them back to pico, imho. stan |
