Please download V5.06.00RC1

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

This includes the following changes from b14

Fixes a bug where the random data in memory on power up could be sufficiently like real data that the firmware interpreted it as real and caused memory corruption

Allows an extra parameter "dontcopyblack" for IMAGE RESIZE and IMAGE ROTATE. The parameter list is now the same as for IMAGE ROTATE_FAST and IMAGE RESIZE_FAST

Includes extra checks for the USB keyboard during File I/O that could result in key-up messages being missed. This was likely to occur on SDcards with many files and particularly if formatted in exFAT.

Includes extra checks for the USB keyboard during editor screen output that could result in key-up messages being missed.

I've been chasing a sprite drawing problem in mode 1,16 for recent firmware.

Here is minimal program that shows the problem on my CMM2 (400 MHz Waveshare)

Sprites are drawn with what appear to be 16 pixel horizontal strips missing/transparent. The strange thing is, the missing parts slowly reappear when other areas of the screen are drawn.

When I save the screen image, the resulting BMP is perfect: no glitches.

' Mode 1,16 Sprite Draw Problem

mode 1,16
cls &hFFFFFF ' white back ground

pausetime = 1000
sz = 50

' load and prepare graphics
page write 2
load png "cobographics.png"
page write 0

do
cls &hFFFFFF
for i = 0 to 9
sprite read i+1,i*SZ,250,SZ,SZ,2 ' 10 coloured balls
sprite show i+1,int(rnd * 12) * 50,int(rnd*10)*50,1
pause pausetime
next i

sprite read 11,500,250,SZ,SZ,2 ' cursor
sprite show 11,int(rnd * 12) * 50,int(rnd*10)*50,2
pause pausetime

loop until inkey$ <> ""

The graphics file (plus the complete game) are here:

Here's one for you, Tom:

When I run the welcome tape in 05.06.00RC2. the logo screen comes up and waits for me to press a key. When I do, I get this:

Error in line 31: A hard error occurred in the low level disk I/O layer.

I can edit all the welcome tape programs so I'm pretty sure the SD card is fine.

I have OPTION SD NORMAL.

I am getting the same thing in Gauntlet and a few other things I tried. I have to power cycle to get it to do anything because if I hit F1 it gives the same error. Glad it's not just me.

Not that I'm glad you're getting errors but I am glad that I'm not the only one this time! It takes at least two people reporting an error before the hardware can be ruled out.

I get hanging with the Welcome Tape during the opening animation. If I comment out the "play mp3" command on line 20 of "./menu.menu.bas", things work much better.

I have this suspicion that something broke in the mp3 player a few versions back, but no proof or demo program yet.

Also, in LunarLander on the welcome tape, there is a subroutine named "help". This is now an illegal name.
The subroutine definition on line 401 must be changed, to "DisplayHelp" for example.
The subroutine calls on lines 208, 212, 332, 336 and 459 must likewise be changed.

I gave it all a smoke test with b13 and other than none of the CSUB programs working and the LunarLander problem reported by @vegipete it was all working. This "low-level disk I/O" error sounds like a firmware or hardware problem above my pay grade.

Recently I've had very limited time to sit at the CMM2 so I've been holding off trying to fix Welcome Tape issues until the latest version of the firmware is officially "released" ... Then I will be asking for help especially from the original CSUB authors.

Best wishes,

Tom

We are experiencing the issue with V5.06.00RC2 not one of the betas. Was that a mistake and you tried it on the RC2?

This is the case in all versions of MMBasic. Geoff is aware

Quote Error in line 31: A hard error occurred in the low-level disk I/O layer.

That is a side effect of trying to fix the stuck keys when doing disk I/O - back to the drawing board �

The problem is that on SDcards with lots of files, particularly if formatted in exFAT searching the directory tree inside FatFS can take several milliseconds which can mean the USB polling stops and KEYUP messages are missed. I put in a poll inside the FatFS code but it is clearly having unintended side effects

Not a mistake, Peter produces betas/release candidates faster than I can test them

I appreciate everyone reporting any issues that they find.

V5.06.00RC3 - just posted

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

Fixes the disk error in RC2 without (hopefully) re-introducing the stuck key issue when using a SDcard with many files

NEW COMMAND

MATH INTERPOLATE array1(), array(2), ratio, array3()

This implements the following equation on every array element

out = (in2 - in1) * ratio + in1

Arrays can have any number of dimensions and must be distinct and have the same number of total elements

Why this new command?

Ask JoOngle

NB: in this release DRAW3D SET FLAG is renamed DRAW3D SET FLAGS

Updated 3D documentation to follow......

MATH INTERPOLATE is very useful to make polygonal animations, something like what updated source of QUAKE 1 use to make smooth animations.

Peter - the MATH INTERPOLATE command will be extremely useful for scaled plotting, very much appreciated. However, is it:

Quote out = (in2 - in1) * ratio + in1

Quote out = (in2 - in1) * ratio + in3

?

Really spectacular work. I'm looking forward to testing and adjusting my stuff as well.

Hi All.

Can someone post some example code of the new command

Quote MATH INTERPOLATE array1(), array(2), ratio, array3()

other than matherp (let him work, I like it when he works. Stuff gets done) I am very bad with the maths on the 3D stuff and really learn a lot from practical code. Thanks

Characterizing the MOD file issue that has been causing me some grief.

My asteroids clone Rocks in Space uses samples in a mod file for sound effects. For this to work, the mod file has to actually be 'playing'. So I created a mod file with the samples, and a single blank pattern.
"play modfile filename$" works great - silence except when I "play modsample ..."

Recent firmware versions broke Rocks in Space, with a system hang at "play modfile". I've been experimenting and discovered the following different fixes:

changing to "play modfile filename$, 8000" seems to fix it,
adding "pause 10" right after "play modfile filename$" seems to fix it,
turning on trace seems to fix it.

The code around the "play modfile filename$" command is:

' Sounds: sounds are stored in a custom MOD file.
' This MOD file contains only a single blank pattern, which the CMM2 will
' dutifully play as silence. However, the individual samples can be played
' on demand while the MOD file is silently playing.
play modfile "RISsound.mod" ', 8000 ' adding ,8000 fixes problem

'trace on ' fixes problem
pause 10 ' fixes problem
'pause 1 ' too short, doesn't fix

hurn = 1 ' hurry up sound number 1 to start
hurs = 1000
settick hurs + 175,HurryUp

'end ' program doesn't hang

' Vector Font 16 x 20
' ascii 32 to 128 - used for number display, ought to simplify the font
load font "Vector16x20.fnt"

It could be that disk access too quickly after the 'play modfile' is the cause of my problem. The extra hint is that the SD access LED is on when the system hangs.
