Hello World :))

My first basic program! A few days ago I setup my first VGA PicoMite and was so taken, I couldn't stop. Have fun!

I tried to make really everything configurable and no end of ideas in sight :)
They move, change colours, can be static with favorites etc.. have a look
I tried my best to comment it so everybody can modify it as easy as possible.

hi dddns,

I am running a RP2040 platform, and it does not support mode 3.
I made some small changes to make your program work on mode 2.

VGAclocks_mode2.zip

Running as a background right now.

Godd morning Volhout,

good to hear! I'm using a PGA2350 on a solder stripboard and that's all I have for testing.

@Javavi
I'd like to use some of your VGAdemo snippets to play with for generating a background. Is that ok with you? Of cause you can feel free to use this as well as all others who are interested :)

One single object is now possible and favorite font & scale is implemented.

I spent the last days making a library out of this splitting up all and end up in a hand full of commands for displaying and setting up objects defined in a "database".

Now I'm new to basic:

Is there a way, to use the content of a string as the variable name for the DIM command?
Is there a way to assign a value to a string, where the stringname$ is the content of another string?

I found a workaround with the "EXECUTE" command but maybe I can't see the obvious..

Many thanks in advance

Hi dddns,
The fight with MMBASIC continues!
You are not alone in this fight,
I also miss the ALIAS NAMES FOR VARIABLES that exist in other programming languages.
For example, I would like to have:
1) ALIAS NAMES for VARIABLES

DIM D% = 123
ALIAS AlsD% = D%

and
2) ALIAS NAMES for ARRAYS with variable dimensions

DIM Arr2D%(100,1)
ALIAS Arr1%(100) = Arr2D%(100,0)
ALIAS Arr2%(100) = Arr2D%(100,1)

P.S.
Now in MMBASIC, something similar works inside subroutines and functions where, when defining, the name of the argument (parameter) is given, and when calling, the value of the variable is passed by reference.

I never typed that much in my life :)) My lost cost cherry keyboard is lost..the cursor keys

So here it is, my first real MM Basic program. I couldn't comment it yet but I thought somebody might want to play already. I tired my best, it shows a picture..

It's completely encapsulated and need nothing before init, runs with explicit option. I hope that this is how it should be for a library, but I don't know. One of my favorites is to re-invent the wheel, so this is done with zero knowledge.

(technical)comments are very much appreciated!

This is VGAclocks Version1

VGAclocksV1RC1.bas.zip

This is a library to draw in a convenient way clock objects.

A clock object consists of parameters stored in a database at the end.
Variables and their content are dynamically created during INIT.

> list variables
DIM CLK_TIMEZONE$(5)
DIM INTEGER CLK_AMOUNT

DIM INTEGER COUNT
LOCAL CLK_BASE_TIME$
LOCAL CLK_INIT_ACTION$
LOCAL FLOAT CLK_DEBUG
LOCAL FLOAT CLK_DEST
LOCAL FLOAT CLK_DRAW_SCALE
LOCAL FLOAT CLK_OBJECT
LOCAL FLOAT CLK_SOURCE

The command has the syntax:

VGAclocks(clk_object,clk_init_action$,clk_draw_scale,clk_source,clk_dest,clk_debug,clk_base_time$)

Draw:
VGAclocks(clk_object,"", clk_x_pos, clk_y_pos, clk_draw_scale,clk_base_time$, clk_debug)

targets for init_action$: INIT, SET_Timezone, SET_SIZE, SET_COLOUR

max objects are 30

object count starts from 1

parameters can be omitted except clk_object

I hope I got the parsing right as this work is directly published and not tested

Have fun

This is noob work. This program is doing three things: parsing the arguments, a "database" and its routines to fill up arrays with mass(mess) data and handing them over to the drawing routine.
Now I think every part has to be reworked and this is more or less brainstorming and by far not finished. I can now turn the page in the manual and rewrite the drawing routine as there are all these fantastic MATH command options I couldn't discover yet. My plan is to even expand the list of variables as e.g the clock hands are anyway a polygon already and I want to make them design able.

In the variable list above only a new variable name needs to be added and the according array will be created and filled up with the content of its correspondent data line label name.
I plan Array(0) of every variable as a buffer..it's not used right now, because the object count starts at 1 and I thought it's more logical to have the array element number according.

Hello :)

I am happy for taking the next big step.

VGA_clocks_V1RC4.bas.zip

Everything is drawn with polygon, circle or arc.
Polygon is such a fantastic command and must be written by a genius.
A line drawn with a polygon looks simply the best. You can achieve any possible line width, by simply scaling the coordinates.

So VGAclocks draws objects, which can seamlessly be scaled.

Every and each element that an object consists of can be configured in terms of colour and size. You can initialize up to 30 objects.

The polygon can have up to 16 corners and is individual for every object and for every clock hand.

The minute/second drawing is now also an polygon.

This program in the main loop:

Option explicit
CLS
Option console serial
VGAclocks(1,"INIT",,,,1) 'debug is on

VGAclocks 1,"SET_TIMEZONE",,13,,1
'VGAclocks 3,"SET_TIMEZONE",,103
MODE 3 : Font 1
FRAMEBUFFER create
FRAMEBUFFER write f
CLS RGB(white)
Dim integer counter

Do
'Memory :Pause 1000
For counter = 1 To clk_amount
VGAclocks counter,"",110,400,300,,Time$ ',counter',"",80,400,300,,"10:10:02"
If Inkey$<>"" Then Save image "b:pic.bmp"
Next counter
' Print @(50,50)Timer:Timer =0
FRAMEBUFFER copy f,n
FRAMEBUFFER write f
CLS RGB(white)
' Memory
Loop

this if you press a key ;) Have fun!

Forgot to say, that I didn't find the time to build sense making coordinates for the clock hands as I am doing nothing but getting the frame done.

I planned numbering of the face to be included, I need to write the routine that does that. BTW: I cleaned up all routines and beside the drawing "engine" for the clock, any object will(could) be possible to draw.

any variable an object has can be altered during runtime by your code and the next frame will be written with that e.g. some colour.

it _should_ run on any VGA platform at least in MODE 2

This is how I plan to vectorize the numbers. Very simple and hard coded coordinates.
Number 1 would need 1 polygon and 2 arcs. If you store these numbers in an array, you can scale them with one command.Its calculated 1:1 in 8x12 and it will look brilliant scaled. finally hand this array to polygon. arc radius x scale for linewidth

I think this is how its possible to print number 2 with few lines of code scalable and rotatable. Brainstorming work as this is all out of thin air.
Here is an Freecad sketch in which only the red constrains need to be changed and the whole gets scaled. Variables are diameter for line width and upper left for spacing.
The other constrains in this drawing are just geometrical.

This one is nice. Just grab the right circle in the middle with the mouse and you can design the 2 within the constrains and move the center of 2'S arc.
All blue values get updated just in time.

edit: of cause I wanted to say constrainTs!

freecad.zip

with line width = 1

with line width = 2

Edit:Final layout sheet for number 2 with freecad. Its very stable now and doesn't crash freecad at all. You can really freely design the shape now.

Hello :)

I posted the above at 6 in the morning sitting 18 hours non stop in fron of my PC doing that. I must be crazy but I think it was worth it.
MM Basic is so incredible superb I cant find words. Thank you!

This is the skeleton of the library I will use. Have fun let the 2 scroll and scale with your cursor keys :)) Here we go:
