Well guy's I am trying to get the mouse working in my first start on the pico 3 using MMBasic while I wait for the psram and wifi chips to arrive.

With the new GUI for HDMI just getting a mouse going is my first step and this is my code so far

OPTION EXPLICIT
OPTION DEFAULT NONE
option console serial
gui cursor on
colour rgb(grey), rgb(white)

cls

const topcaption= 1, btmcaption = 2, Memcar = 3, Memlog = 4, Memfin = 5
const topF = 6, list1 = 7
'fill = rgb(white)
gui frame #1, "", 4, 4, 636, 30, rgb(grey)
gui frame #2, "", 4, 450, 636, 30, rgb(grey)

'gui frame #topF, "", 4, 4, 636, 30, rgb(red)
dim k$
dim club$(4) length 16
club$(0) = "Member Number" : club$(1) = "Member Name" :club$(2) = "Car"
club$(3) = "Logbook Number" : club$(4) = "Status"

gui listbox #list1, club$(), 5, 5, 200, 30, rgb(white), rgb(red)
do

k$ = Inkey$
If k$ <> "" Then
' Default step 4 px; if the key arrived shifted, MMBasic delivers
' a different code. Keep it simple: hold Shift-equivalent on PS/2
' by using upper-case letters of D/U as "fast".
stepx = 4
Select Case Asc(k$)
Case &H82 ' LEFT
mx = mx - Stepx
Case &H83 ' RIGHT
mx = mx + Stepx
Case &H80 ' UP
my = my - Stepx
Case &H81 ' DOWN
my = my + Stepx
Case 32 ' SPACE -> momentary click
GUI Click mx, my
Case 100, 68 ' 'd' or 'D' -> press-and-hold
If held = 0 Then
GUI Cursor mx, my
GUI Click Down
held = 1
EndIf
Case 117, 85 ' 'u' or 'U' -> release
If held = 1 Then
GUI Click Up
held = 0
EndIf
Case 27, 113, 81 ' ESC / 'q' / 'Q' -> quit
Exit Do
End Select
' Clamp to screen.
If mx < 0 Then mx = 0
If my < 0 Then my = 0
If mx > cw - 1 Then mx = cw - 1
If my > ch - 1 Then my = ch - 1
GUI Cursor mx, my
endif

pause 1000
loop

sub touchdown
local integer tx, ty
tx = touch(x) : ty = touch(y)
if not (tx = -1 or ty = -1) then
gui cursor tx, ty
' mx = tx : my = ty
endif

Now looking on search I did see the mouse option and I put the mouse dongle in the usb hub which works in edit but sadly not in my code.

> option mouse sensitivity 1.0000

G'day Bryan,
I think the command you are looking for is:
GUI CURSOR LINK MOUSE

That should get it working with a bit of luck

The PCB's arrived Monday, now I just need to find time to tinker with them.
Thanks again.

Regards, Lyle.

Nope that didn't work now I used the code from the Advanced Graphic's Manual which I got off Peter's github site and it is dated to 2015 where the GUI Cursor on is used.

Now using that code an arrow is displayed at the centre of the screen which is static so I did try using the arrow keys only to find

[64] GUI Cursor mx, my
Error : -1 is invalid (valid is 0 to 639)

So copying code from the manual has got me again

Also I'm going to get back my pico 2 as trying to play a mp.3 on this pico 3 in both micropython and MMBasic won't work where when I tried morning in MMBasic get a heap memory error when I tried a MP.3 where with the pico 2 it just worked.

Are you by accident looking at CMM2 manual or the like instead of PicoMite manual?

Quote Peter's github site and it is dated to 2015

That is well before the PicoMite.
Latest PicoMite V6.03.00 firmware package on Geoff's site has Advanced Graphics Functions.pdf in the Extra Documentation folder.

Quote CLICK(DOWN) Will return true if the screen is currently being clicked on using the mouse.
CLICK(UP) Will return true if the screen is currently NOT being clicked on.
CLICK(LASTX) Will return the X coordinate of the last location that was clicked on.
CLICK(LASTY) Will return the Y coordinate of the last location that was clicked on.
CLICK(REF) Will return the reference number of the control that is currently being clicked on or zero if no control is currently being clicked on.
CLICK(LASTREF) Will return the reference number of the last control that was clicked on.

And there is the Keyboard/Mouse/Gamepad chapter in the main manual.

Hi Bryan,
You may just be over-thinking it, the GUI system looks after most of the mouse stuff.

Just tried this and it works on the Pico Computer 3 received Monday.

RESET Pico first to clear previous stuff in memory then at prompt:

GUI CURSOR LINK MOUSE
GUI CURSOR ON

And now the cursor is moving around the screen with the mouse

Regards, Lyle.

First with that Advanced Graphics Manual I downloaded it off the github to get the newest version.

I went and grabbed my pico 2 so I can try both tomorrow.

Thanks for that tip Lyle

and it's the first thing I'll do in the morning now mate could you try playing a mp.3 to see if you get that heap error,

Regards Bryan

Hi Bryan,
Tried playing 196kbps MP3 from FM and command prompt and both working fine from SDCard, not sure why you are having trouble, our option list is almost the same.

I normally disable the MODBUFF as I have the game playing skill of a Sloth crossed with a Hippo but testing with it enabled makes no difference.

Perhaps try a flash-nuke / reflash and see if it makes a difference.

Also MP3 playback uses 81kb of memory and GUI controls use a bit as well, maybe PSRAM will help? (none fitted on this board)

Regards, Lyle.

Just looked at the update from Mouser and the psram and wifi chips should be here on Monday so not long

I will do a flash nuke and try again this morning, now for a laugh yesterday I tried loading up a JPG only to find the error progressive JPG's are not supported so tried a BMP of one of the scope pic's not realizing it was 1.27mB

put it on at 3.30pm and at 3.45pm about 30% of the screen was done so did a reset.

Well had a session with Claude and it went down the non GUI route where it is keyboard input and ran out of my time limit for 5 hours

so I will try and again later as when I asked for a photo to be attached went over my quota.

Well just paid for 12 months with Claude and when I get a thought the answer is there, I have done this so I can get this car club project done where in the chat it was said where I asked when a member brings up a phone how can we get the jpg across and is MMBasic or Micropyton the best.

Well the answer was micro python hands down with the wifi like when I asked for the best way to get a picture from a members phone the wifi can act an acces point but to render the pic to suit the OS a new pyton app needs to be made to handle this so I have paused this project until I can get the psram and wifi chips on

But the future is looking good as when I get a thought it can be put to code.
