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 all,
I'm just wondering if anyone can help me, I am only new to programming and I'm trying to create a photo viewer using a Micromite Plus LCD Backpack.
Is there already a thread on this or is someone able to direct me to somewhere I can find the code to do this?

Hello and welcome.

If you happen to use the Micromite Plus, the MicroMite Extreme(MMX), or the ARM-mite, most of the work is done for you.

See the LOAD IMAGE command, page 54 of the advanced manual for the MM+ series of chips. The image must be a BMP(bitmap), but it can be a true-colour 24-bit BMP file, you just need to have the image on the SD card.

Done.

Thanks Grogster, I'm almost there now but I'm getting a syntax error. Is there a typo in the manual? Thanks

There is no typo. The command is:
LOAD IMAGE filename$

Where filename$ is a string expression, variable or constant. If you are using a string constant for the file name it should be surrounded by double quotes. For example:
LOAD IMAGE "TIGER.BMP"

I bet that is your problem.

You should post your code, then we could spot what you are doing wrong.

OK at one point in the manual it shows LOAD IMAGE file$ [, x, y] I was trying to include the x and y section but it turns out I don't need it.

Yes, that does catch a few newcomers. The square brackets indicate an optional parameter for any MMBASIC command, so if you don't need to specify them, don't.
