Thank you very much for the swift turnaround Peter.

I can confirm that it passes all my tests (though I can't comment on MEMORY SET WORD as I don't have any unit-tests for it yet).

Thanks again,

Tom

Fixes bug in TIMER= command when value is greater than 70

Extra syntax option for BITBANG WS2812

Existing version

BITBANG WS2812 type, pin,colours%()

Also now allowed

BITBANG WS2812 type, pin, nbr, colours%[()]

The new variant allows you to control a single LED which wasn't previously possible in a clean way e.g.
BITBANG WS2812 O, 3,1,RGB(RED)

Should a newly updated and OPTION RESET CMM2 list the current display as 24x80 ?

It seems to be acting like it is 50x100 which is what I was expecting and what the EDITor is using too.

Best wishes,

Will look at it but away from home at the moment and didn't pack a CMM2

@Peter,

I am sure the CMM2 is as complete as anybody could wish.
But I do have a request for additional functionality.
Could we add a simple 2D plot command ?

Below example from Octave is not MMBasic, but is explanatory of what I am envisioning.

x = -10:0.1:10; # Create an evenly-spaced vector from -10..10
y = sin (x); # y is also a vector
plot (x, y);
title ("Simple 2-D Plot");
xlabel ("x");
ylabel ("sin (x)");

It is the simplicity of the "plot" command that helps people analyze data.
This is as simple as the output would look like, nothing fancy.

I know this can be done in MMBasic. Every project I re-invent the plot function, since I am very visually oriented.

Is this something that will still fit in the CMM2, and are you willing to code it up ?

Thank you in advance,

Volhout

It's not my baby, but why would we need graph plotting in the firmware? Is this not the perfect use for a .INC file, I'm sure our prolific @William Leue or any number of others could knock one off for this purpose. Possibly if you wanted 3D contour plotting you would need firmware level of performance, but that's what CSUBs are for.

Best wishes,

Tom

@thwill

You are right. All the graphics functions are there, so it is definitely possible in MMBasic, and not CPU intense. I simply did not create an ".inc" yet, I'll do that my next project, so I can benefit for the next...

I was stunned by the simplicity of the implementation in Octave. Hence the request.

I will withdraw my request.

System hangs with PIXEL FILL x,y,colour if x and/or y is outside the screen size, either less than zero or greater than MM.H/VRES.

ex: immediately after power up, type
PIXEL FILL 10,610,RGB(BLUE)
Reset needed to regain control.

This is with version 5.07.00 @ 400MHz.

Will make it cause an error - thanks

V5.07.02b3

https://geoffg.net/Downloads/Maximite/CMM2_Beta.zip

Fixes bug in Option RESET setting display width and height
Fixes system crash caused by setting coordinates outside screen with PIXEL FILL. Now gives an error

New Functionality
NEW subcommands for SETTICK
SETTICK PAUSE, myint [,tickno] ' pauses the tick so that the interrupt is delayed but the current count is maintained
SETTICK RESUME, myint [,tickno] ' resumes the tick after a pause

The polygon command doesn't appear to accept -1 as a valid fill colour.

=======
I can't decide if PIXEL FILL outside the screen should give an error or just ignore the command. Other drawing commands don't mind offscreen coordinates. (Thank goodness ;-)

Or even clamp the coordinates to the screen and fill from there. (Unlikely to be useful.)

ie: PIXEL FILL MIN(MAX(x,0),MM.HRES),MIN(MAX(y,0),MM.HRES),fillcolour

Why would it? If you want a transparent polygon just leave off the fill parameter. I think this is the same (or should be) for all fillable shapes

Quote I can't decide if PIXEL FILL outside the screen should give an error or just ignore the command.

I wasn't sure either. In general I don't like commands that do nothing and then return without an error but I can understand that in some cases it makes the Basic coding easier. In most cases I have made this sort of thing an error so will probably leave as-is

For me the error is right way. If you think there can be error, you can still catch it with ON ERROR SKIP and calculate proper coordinates...

That's fine at programming time, but not if the choice happens at run time.

If filled or outline is a user choice, more code is needed for just the polygon command:

IF fillcolour < 0 THEN
POLYGON n,x%(),y%(),outlinecolour
ELSE
POLYGON n,x%(),y%(),outlinecolour,fillcolour
ENDIF

With BOX, CIRCLE, RBOX, TRIANGLE, that if structure is contained in the command itself.

V5.07.02b4

https://geoffg.net/Downloads/Maximite/CMM2_Beta.zip

Implements READ SAVE and READ RESTORE
These allow a subrountine or include file to read its own data whilst preserving the data pointers for the main program
e.g.

dim a(20)
data 0,1,2,3,4,5,6,7,8,9
data 10,11,12,13,14,15,16,17,18,19
for i=0 to 13
read a(i)
next i
readmydata
for i=14 to 19
read a(i)
next i
for i = 0 to 19
if a(i)<>i then print i,"ERROR",a(i)
next i
end
'
sub readmydata
local s$(7)
local i
read save
restore testlabel
for i=0 to 6
read s$(i)
next i
read restore
for i = 0 to 6
print s$(i);
next i
print ""
end sub
testlabel:
data b,c,d,e,f,g,h

I seem to have found a combination of data that locks up my CMM2 when trying to draw a 3D object.
Altering the z value (larger values) in the DRAW3D WRITE command (line 27) can clear the freeze, as can changes (lower values) to the z_viewplane and y_camera values in DRAW3D CAMERA (line 21.)

The pyramid has no base, for what it's worth.

Edit: Maybe related, there are drawing artefacts if the object is positioned at large plus/minus x values, y=0 and z passes through the region near 0. (Camera at y=0.) I think I can provide sample code if required.

> list
dim integer cindex(4)=(rgb(green),rgb(0,128,0),rgb(0,64,0),rgb(0,32,0),0)
dim q(4)
dim integer i

' Pyramid definition
dim integer nv2=5, nf2=4 ' pyramid has 5 vertices and 4 faces - no bottom face
dim v2(2,nv2-1) ' coordinates of each vertex
for i = 0 to nv2-1 : read v2(0,i),v2(1,i),v2(2,i) : next i
data -6,-4,-6, 6,-4,-6, 6,-4,6, -6,-4,6, 0,9,0
math scale v2(),20,v2()

dim integer fcnt2(nf2-1)=(3,3,3,3) ' number of vertices for each face
dim integer ecol2(nf2-1)=(2,2,2,2) ' colour of edge of each face
dim integer fcol2(nf2-1)=(1,1,1,1) ' colour of each face
dim integer fv2(math(sum fcnt2())-1) ' vertices for each face
for i = 0 to math(sum fcnt2())-1 : read fv2(i) : next i
data 0,4,1, 1,4,2, 2,4,3, 3,4,0
draw3d create 2, nv2, nf2, 1, v2(), fcnt2(), fv2(),cindex(),ecol2(),fcol2()
' End pyramid definition

draw3d camera 1,500,0,500

math q_euler rad(327),0,0,q()
draw3d rotate q(),2

' on your marks, get set, crash...
draw3d write 2,0,0,159

==================
Also, a slight anomaly, largely user error:

If you type

autosave "filename.bas"

but do NOT press enter, then send a text block from the console, the first line will get appended to the line you just typed. If the first line is a comment, all will work pretty much as expected, although that first line will be gone from the resulting autosaved file, and the command history (up arrow) will show the comment appended. If the first line is not a comment, expect an error or some other strangeness. And if the cursor is still inside the quotes when the upload begins...
