Hello Peter,

thank you for the new update again!
Just for my interest what are the reasons of performance profiling tools are not working with Webmite versions?

Thanks a lot!

Hello Peter again,

Tested long lines in new version. Something is still wrong when I press backspace after a long line.
Beginning of all other line I can’t reach with the cursor until I press enter or quit the editor and go back.

And mark mode color is changing always to the color of the last selected character. See picture.

Explain more, where is the cursor positioned? By backspace do you mean the back key on the PicoCalc?

Hello Peter!

I try to explain better:
Cursor is standing in the beginning of a line. The previous line is a long line. Then oress back key on Picocalc. Cursor will jump to the end of the previous long line and also the next line will come with the cursor.
But from now I can go to the beginning of the line with cursor (and Home) only in this line. Other lines (previous ones and next ones) - where I can see only the second half of the lines I can’t navigate to the beginning of the lines.

I hope so I was better in explanation.

Version V6.03.00B1 is not stable for I2CLCD and with V6.03.00B0 there have been no problems so far.

The LCD screen is jamming. Strange characters appear on the bottom line or are completely jumbled, and the chr$(0) degree sign becomes a square and the cursor appears in the top left of the LCD display and blinks.

With respect, that report is as much use as a chocolate teapot. Program? other connected devices? Nothing has changed in I2C but lots has changed elsewhere so if there is an issue it will relate to other code in your application.

Peter,

I understand. If I manage it, I will try tomorrow to extract a part of the program from the whole where the problem occurs with V6.03.00B1.

Jan.

I've tested with PicoMiteRP2350V6.03.00B1 on a RP2350A
> i2clcd init &H27
> do:i2clcd 4,1,str$(i)+chr$(0):inc i:loop
and it runs until I get bored

G'day Peter,
Some further testing of the Stepper commands has raised a question, can you please clarify:

If I understand this correctly, to add G-Code to the buffer we have:
STEPPER GC    - to add directly to the buffer, no variables
STEPPER GCODE - to add to buffer, variables allowed (are strings allowed?)

Is there a way to send a string read from a file or created in a program to the G-Code buffer? I have tried several methods but no joy so far.

Currently I am using EXECUTE to feed strings into the buffer but not sure if this is a good or correct method, it does work.

Thanks again for all the new toys to test, its a joyous challenge trying to keep up.

Regards, Lyle.

Lyle
What version are you using? I'll post a test version that supports
GCODE GS gcodestring$
This would allow you to read from file using input abd write directly to the stepper.

Peter I'm using the latest firmware V6.03B1 and Lyle has agreed to help with the stepper code for my Surface Grinder project.

That shipment of the DM556's should be here next week so I will get on and mount the stepper motors so between all of us this new stepper code can be used as a state machine where it just works.  

Now in the stepper PDF if you can give more info on using the buffer using $'s will go along way in my understanding of what I need to do get this project done.

Also a comment on using FM in my case at the moment the divide between A: and B: drive is 50/50 now trying to read the MP.s songs as they have full details the ability to move the middle divider over to the left so the B: folders can be fully seen would be a huge bonus

Here is a picture to show what I mean




As you should see I had Kasmi playing where A: drive doesn't need 50% of the screen

Version? hdmi, normal vga?

PicoMiteRP2350V6.03.00B2.zip
 

All versions
Optimisation of FOR/NEXT. Note: FOR/NEXT is over twice as fast as DO/LOOP even with the performance caching enabled. Wherever possible use FOR loops rather than DO loops.

RP2350 versions
New stepper subcommand to allow the whole gcode to be sent inside a MMbasic string variable
STEPPER GS gcode$

Additional bytecode optimisations for relevant versions - see manual for details

G'day Peter,
Many thanks once again, STEPPER GS tested on both HDMIUSB and RP2350B boards and appears to be working well  

Normal test platform is PicoMiteRP2350A base edition but sometimes its whatever is plugged in / on hand at the time (as above)

Further testing to follow, later in the week all going well.

Regards, Lyle.

Hello Peter!

Thanks for B2.
I found one problem with it I have never experienced in previous versions.
I have a simple test program based on the user manual. Reading data from openweather API.
Connection is ok open, get and close.
But at the first JSON instruction the system sends the attached message and restarts. Then I lost wifi connection, autorun setup.
I can use option wifi again, but same result.

Thanks ,
