Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi.
I used to use some code written by matherp to display pictures in .ppm format on a ILI9341 LCD panel using an sd card. This code no longer works with the latest firmware for the 28 pin Micromite.
Matherp has released an update but I cannot seem to get it to display .ppm pictures.
Everything else seems to work great.

Any ideas?

Thanks.

Dave.

This is the BASIC code I'm using.

const writefile=3
const opendir=4

cls
displaypicture("tiger2.ppm",0,0)

And I'm using it with this C code.

Finally got the (singular) 'grey matter' moving here...

Your cFunction code is missing two important functions:
SetRegion() & DisplayBuffer(), both called in your
DisplayPicture sub!

I would include it here, but I am not on my Windows machine
(gotta love this RaspberryPi 4B!), if you want I can get it.

Can't locate the source right now, but here's the hex data.
I have these placed as the first & second functions in the cFunction code
block, however I think anywhere is acceptable.

Still Having problems with this.
Everything works great, it just will not show a picture.
just gives an error.

Error : SDCARD is not declared.

I've spent weeks and weeks on this, and every bit of spare time I have.
I've tried older firmware versions and the best I got was a few lines of the tiger pic along the top of the screen.

I may have to give up on this one.

Finally got it working!

Turns out it was the SD card  

I was using an old 1gig card, changed it for a new 32gig and it worked first time

Ahhhh, the old 'Not all SD cards are equal' paradox....

I suspect that the MM Cfunction was probably clocking the old 1GB card faster then it could handle.  Bigger capacity cards don't have that problem, as they support much faster clock speeds.  I think that would be where the problem is, but I could be wrong - matherp will correct me if he reads this thread and it is something else.

It's a shame in some ways, that the older lower capacity cards GENERALLY are not supported, as I have heaps of old SD cards from 16MB(yes, Megabyte!) up, and they are pretty much useless for anything modern, but they could hold quite a bit of stuff on a MM system.

If matherp DOES read this thread, I would be interested to know if it is simply clock speed that is the reason behind older cards not working or is it something else.  I guess it would be relatively painless to recompile the source for a slower SPI clock for the SD card, but that really is taking a step backwards, when even 16GB or 32GB cards are very cheap new these days, so why bother.  Food for thought only.

A tad late perhaps....

The SD card speed can be set in MM.Startup.

SDcard 0,CSpin,speed 'must be called in MM.STARTUP

CSpin is the MM pin number connected to the SDcard CS input
"speed" controls how fast the SPI bus operates. If omitted the bus runs at 5MHz which should suit most SDHC cards. Assuming the CPU is running at 40MHz, a parameter of 0 runs the bus at 20MHz which works for me on Class-10 cards.
Values in the range 0-fastest to 10-slowest should cater for any speed of card. The default if omitted is 2 (5MHz).
