I haven't got a VGA system with PSRAM to test against - sorry

Will reconfigure to HDMI and try. Lacking a HDMI breakout this is VGA but now have the guts and will to cut a cable.
800x600 is really nice ;)

Hi Peter,

The official RC8 for VGA 2040 is good!!!

             

Sound has never been better. Even games like Petscii are a lot more professional now music changes happen plop-less. Thank you for your persistence.
I will run RC8 through all my programs, but the ones that caused problems did run already.

P.s. I always use page up and down in the internal editor. Much faster in 70kbyte sized program.
So I never noticed the scroll problem.

Phew..... at last

ddns: just jury-rigged a VGA RP2350 with PSRAM using a one of my RP2350B DIL boards and no issues with 800x600 even with PSRAM enabled. What board are you using?

V6.00.02RC8 is available on

https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip

My current intention is that functionality will be frozen after 6.00.02 with the only changes after that being bug fixes that seriously impact usability. I think it's about time I moved on to another project  

If you're looking for a challenge, how about making a 6.00.02 version of MMBasic that runs on the PicoCalc?

A Pimoroni PGA2350. Any chance that It runs
better with the HDMI firmware?

That's right!  
And also on the HDMI/USB reference board.

But I did find one PLOPP after all, reproducible


Sorry Peter. But I can live with that.

Shouldn't that work?

I've narrowed the list variables problem down a litte ....

the following statements already spoil the list variables:

--------------------------
 '
 OPTION EXPLICIT
 OPTION DEFAULT NONE
 
 dim string a, b, out_str(20)
---------------------------
Error: Invalid address - resetting

changing the DIM to

dim string a, out_str(20)

works. If I have 3 vars defined as string and one is an array, it crashes.

No chance. Describe the issue properly, which firmware, what options, and provide example programs/sound files if you want a fix, otherwise forget it.

Hello Peter,
I'm afraid you misunderstood me.
The "problems, problems..." was referring to the posts of my predecessors, who keep finding new bugs or "minor issues."
And the "problems, problems..." appears in the song - hence the link to the YouTube video - I hoped you liked the song and could laugh?

I'm trying to define a 3 row, 1 column array I need for a matrix multiplication. The code below gives Error: Dimensions

What's wrong with this?

option base 1
dim a(3,1)=(4,5,6)

a(3,1) should be a(3)
Without knowing the dimensions of the second array, I am guessing - silly thing to do.
To do what you are attempting this would work (if I have my maths correct)


If that isn't suitable.
try
DIM a(3,2) and fill the second row/column with zeros

I'm trying to solve three equations in three unknowns

x + 2y + 3z = 3
2x + 4y + 5z = 4
3x + 5y + 6z = 5


The coefficient array is
1 2 3
2 4 5
3 5 6

The answer array is
3
4
5

To find the solution array (x, y, and z), I multiply the inverse of the coefficient array by the answer array to get the three solutions to the problem.

The answer array and solutions array should be 3x1 matrices. Why doesn't MMBasic allow the two 3x1 arrays to be dimensioned?
Edited 2025-03-30 13:35 by toml_12953

Some time ago I think Peter mentioned that array dimensions have to be 2 or more.

Edit.
Maybe I remembered that wrong, but as it doesn't work perhaps not.

MMBasic doesn't allow single element arrays. I wish it did for reasons such as array multiplication but it doesn't. I don't think this is something that could be easily changed as it is fundamental to the way the variable table is built

https://www.thebackshed.com/forum/ViewTopic.php?TID=17485&PID=230590#230590#230590

Have not found any mention of a minimum in the manual.

For your purpose a second row of zeros seems to work

I think that you can use MATH INSERT and MATH SLICE to interface to singe dimension arrays

Shouldn't that work?

No: a mode 3 buffer takes 153,600 bytes so after the framebuffer is created there isn't enough left for the layerbuffer. It could work on a version with PSRAM IFF you define the layer buffer first.

Fixed if you re-download. Note the bug applied to all versions including RP2040. It was just fluke as to whether it impacted in a given circumstance or not (current state of the stack)
