Sounds like a system stack issue, I'll reduce the heap to 316 from 320 in the next beta.

Peter!

I tested long lines, mark mode behavior.
Working good, only one thing I found.
I really can’t remember how was it in previous versions.
If I mark line(s) or char(s) then unmark them (move the cusror opposite direction) chars or lines looses its color in editor and became black and white.
Then if I exit from mark mode with ESC or F4 or F5 colors are coming back.

All other are working good including profiling pages!

G'day Peter,
Using V6.02.02B8, if PEEK(STEPPER ACTIVE) is used before the stepper system is initialised, or after STEPPER CLOSE, this causes the PicoMite to lock up, only hard RESET will fix.

> option list
PicoMiteHDMI MMBasic USB RP2350A Edition V6.02.02B8
OPTION SERIAL CONSOLE COM2,GP8,GP9
OPTION FLASH SIZE 4194304
OPTION COLOURCODE ON
OPTION KEYBOARD US
OPTION RESOLUTION 800x480 @ 333000KHz
OPTION DISPLAY 40, 100
OPTION SDCARD GP22, GP2, GP3, GP4
> ? peek(stepper active)
(no response)

Just experimenting on a PicoMiteHDMIUSB at the moment, usually use base PicoMiteRP2350

Further to my previous post, it is probably best to leave the enable signal as is, I will post a circuit on the Stepper Thread that should work.

Regards, Lyle.

Hi Peter,
Congratulations on the latest (beta) release!
Is there already an equivalent to the MM.INFO$(SDCARD) function for the new C-Drive (USB stick)?
Regards
Michael

Good evening Peter!

I continued testing long lines on Picocalc.
When I press backspace in the beginning of a line after a long line I got the same problem. Check picture. The other lines I will never see (expect the long on where I can navigate) until I escape editor and come back.

I have two files here in a ZIP archive that are causing problems in FM under PicoCalc:
README.md and rgb.bas

When I run rgb.bas, the font size in FM becomes smaller, and in the text viewer, the text is not only smaller but also black on white (After the program has closed again).

When I open README.md in the text viewer, the viewer closes while the last page is still being displayed, and the text in FM is displayed in a larger font. When I open the file with F2, I can no longer close the editor with ESC:
LINE TO LONG
problem.zip

Frank

(P.S.: Maybe it wouldn't be such a bad idea if you could adjust the font size in the file manager and text viewer???)

Peter,

Could it be that the PicoMite occasionally freezes on values that appear in, for example, I2CLCD 1.13, Chr$(status_meteo) in a program with an LCD 2004 display?

I thought it no longer occurred in V6.02.02B5, but it does after a certain time; see the printout below with the error message and a snippet of the program from the message.
The display works normally until the error message, then the status R, the outside temperature, and the degree sign (which is Chr$(0)) disappear, leading to my suspicion regarding chr$().

The program is far from finished, and I am trying to convert it from BascomAVR to MMBasic.

Jan.

Jan, it is nothing to do with chr$ which cannot give that erro. Almost certainly stack overflow. I;ve already said I will reduce MMBasic heap and increase stanck in the next beta.

Peter,

Thank you for your response to my question.

I appreciate all the great commands and functions available in PicoMiteBasic.

Jan.

Quote When I open the file with F2, I can no longer close the editor with ESC:
LINE TO LONG

This is correct. The editor can't handle lines > 240 characters (255 with a tolerance). You will have to split the line. The response of the LIST command is caused by the same problem. I can probably solve that but the editor issue is fundamental to the way MMBasic works

I'll try and change it so non-basic files can have longer lines but for basic files it is a definite no.

That would be fine! It goes without saying that lines in BASIC can't be any longer...
