Quote Is there any possibility of putting Draw3D on the PicoMite, even if it has to be as a sub-command of something else ?

Hi Peter,

Draw3D looks impressive !! Especially for an SPI LCD display.

Thank you Peter.

I've only had the briefest hack (nothing in a shareable state) but it looks like with all your work the Game*Mite can play a passable game of @Vegipete's "Stellar Battle in the Seven Green Hills Zone" even with the SPI display.

So many games to write/port, so little time ...

Best wishes,

Tom

Looking at the .OPT file on the PC with a Hex viewer it seems to have all the data.

Edit
That .OPT file was saved from WebMite MMBasic Version 5.08.00b2
After reinstalling the options the .OPT file saved from b5 re-loads correctly.
Presumably some slight difference in the format or the way b5 reads it.

Edit 2
It isn't a problem with Xmodem as sending the new .OPT to the PC and back also works.

Hi All

Not sure if the right place for this request....

When using

WEB scan NetScan%()

the docs state that if the array is not large enough the results may be unpredictable. (? Like overwriting other memory areas)

The problem is that we don't know how many wifi networks it is likely to come across.

Why not

WEB scan SSID$

How many people really download a list and then pick one to connect to.
Don't we usually know which SSID we want to connect to ?
It would save some valuable memory. I had to print out the list and worked out that,
the 1024 I nominated was only a third of what was needed.

Hi All

Didn't realise that each char (byte) was stored as PART OF an Integer.
Read the wrong part of this statement.

Quote When creating these arrays they should be defined as single dimensioned integer arrays with the number of
elements set to the number of characters required for the maximum string length divided by eight. The reason
for dividing by eight is that each integer in an MMBasic array occupies eight bytes.

I have about 12 networks around me and when I counted the bytes in each SSID statement made that erroneous conclusion.

The concept of the suggested command still stands though.

Hi Peter,

Line width of a drawn line does not appear to be working on the latest Beta5, I have tested box, circle and line AA they are all fine, just line itself. I have only tested on an LCD currently.
Forget it, doesn't work for diagonal lines.

Back to Lines again, should Line AA be able to accept arrays as the input parameters, the same way that Line itself does, currently it does not, but the early release manual implies that it will?

Quote I've limited the VGA version to 252MHz. Testing has shown memory contention between the two cores at 378MHz can result in strange errors that are not present at slower speeds

Hi Peter,
Could this be a power problem? I was seeing something similar on a LCD PicoMite, using background screen updates, where if I ran it at 252 all was fine, but if I used 378 it would have random errors or lock ups, I tried adding a small heat sink in case it was heat related, (second CPU now active), nothing, I added extra smoothing/storage capacitors, nothing, eventually I realised the LCD back LED was drawing quite a lot of power, there was no brightness control, so I stuck a small resistor in series to reduce it's current, suddenly all was well again. :-) I've just realised that a VGA Pico at 252 draws about 125mA and at 378 it draws 160mA, probably higher in bursts, Just a thought.

Seems I'm a bit perverse, ;-) at one end, my solar fridge controller, I'm running as slow as possible to get power consumption down to about 5to7mA (from 12V) with and without a 2 line display, on the other hand 160mA to run it flat out, such is life! :-)
Regards, Kevin.

@Peter,

I have been playing with PicoMite for over 2 years now, and have been amazed at what has been achieved on this platform.
I feel feature wise (maybe not performance wise) this basic exceeds even the flagship CMM2.

Since I have been following every incarnation of the MMBasic on this platform, I know that features have been added (sometimes at my personal request) in a way they where easiest to implement. I remember the DMA's for PIO. And recently the changes for fast copying of sprites from flash to video ram.

With the growing, there are a few items that are out of harmony.
Again, I understand that this basic is standing on the shoulders of smaller ones (CMM1) and has to live up to the expectations of larger ones (CMM2).

But for the sake of the quality of the basic, and consistency of the commands there are few things that I would like to issue.

1/ the BLIT/SPRITE confusion and translations. This would not be a problem if one was used on a CMM1 and the other on a completely diffent platform (i.e. CMM2), but this is both PicoMite.

2/ the colors. Every PicoMiteVGA program I see has (at the bottom) a set of DATA lines to convert RGB(xxx) colors to a number. And depending if this is a program that works on sprites, or works on display layers, the DATA set is different. Somthimes you use color number(index) as in FRAMEBUFFER LAYER 9, sometimes you use color as in CLS RGB(MAGENTA).

You will have come accross these when writing the user manual for PicoMite and PicoMiteVGA.

For the Petscii Robots program I hope you do not change any of the above, but for consistency and quality of the MMBasic it would be better.

Volhout

As for the color numbers, these are chosen such that 1 simple line of math could translate from color number to RGB value. I think a lookup table in ram (8 bytes) could do a mapping, or a full lookup table (64bytes) could to the number->32bit RGB translation immensly fast.

Using color numbers: Currently we have RGB 5:6:5 in the CMM2. Meaning that in the 24 bit RGB values there is RRRRRxxx GGGGGGxx BBBBBaaa used. In the "aaa" value you could "hide" 8 colors. And if you would use the lowest 4 bits (Baaa) you could hide all 16 VGA colors in the 24bit RGB value. You would loose exactly 1 color (ultra dark blue) in the CMM2 65536 color pallette.

IF color < 16 THEN color number, ELSE RGB value.

And this could then be used everywhere where color is used. Combined with the above look-up table that would make the use of color in PicoMite/PicoMiteVGA consistent over all commands.

No easy solutions to any of this

Quote And recently the changes for fast copying of sprites from flash to video ram.

These aren't "sprites" this is a clear example of BLITting

The MMB4W, CMM2 and PicoMiteVGA support true sprites hence the SPRITE command. The PicoMite only supports BLIT hence the BLIT command

The PicoMite supports true RGB888 for displays like the SSD1963 so there are no "spare" bits. The CMM2 has a ARGB4888 mode and MMB4W is always RGB888 or ARGB8888 so definitely no spare bits.

The FRAMEBUFFER commands on the Pico versions are clearly special cases and work in colour nibbles hence using a number between 0 and 15. You can't sensible use these commands without understanding this.

Note in the implementation of merge in the CMM2 and MMB4W I use the RGB function for colours because these are true colour and the merge works in PAGES and not framebuffers. The FRAMEBUFFER command on the CMM2 and MMB4W is completely different in intent to that on the Picos

There are and will be differences. These are inevitable given the different architectures and capabilities of the platforms

Thank you for explaining

I fear I have to admit I used some of these commands without actually undestanding them

I just switched back to trying vga mmbasic cos I got a 7" monitor. Shoe boxed the lcd boards and cleared the table dedicated to pico vga.
Tried 16 sprites bouncing around and box to erase each. then tried frame f and cls, no box erase.
Not much visual difference for 16 sprites but amazing how fast , vga and spi ili.

Hi All

I know that MQTT is not on the priority list , BUT is it possible to get
MM.ERRNO and MM.Message$ updated by WEB MQTT PUBLISH.

Depending on how I disconnect at the "Broker's" end , it may throw a
"mqtt_publish: TCP disconnected"

and I have no way of catching it.
