Hi tenij000, If you search the forum for "GFXterm". There is a terminal program that supports graphics. I think it supports VT or ANSI standard graphics commands. I think it is very useful if you have no other than terminal to being able to see graphics. Is your terminal dual screen ? One for editing, and one for graphics ? Can you use the built in editor ?

@tenij000 How did you accomplish that on the Pico side in MMBasic? Did you set up a virtual display driver (with OPTION LCDPANEL USER hres, vres)? Or via OPTION LCDPANEL VIRTUAL_C? |

python script just looks for the user input then does the drawing if connect to pico whit drop down menu you can send code at left window also at right bottem a 1 line can use to send a single command |

but how does that virtual display work |
||||
| bfwolf Senior Member Joined: 03/01/2025 Location: GermanyPosts: 166 |
OK, I understand: The Python script checks what the Basic program would do and then does it itself? See in the latest PicoMite manual, page 104 for OPTION LCDPANEL VIRTUAL_C : The PicoMite just draws to RAM which could be read out and translated to GFX-teminal-command-sequences. Similar with "OPTION LCDPANEL USER hres, vres": Look into the file "User Display Driver.txt" packed with the distribution. In short: You supply a few drawing functions/subprograms, which are called by MMBasic when drawing text or figures. So you always know what's going on and may translate/transmit. |
