Flowcode Support Board

Hi there guys,

I'm trying without luck to display a bitmaps on an ILI9341 SPI LCD, just simulation at the moment. But doesn't seem to work at all.

I've tried different file formats without luck. Is there any way to have a look at the component to see if we can adapt it to take PNG files as they utilize much less space in ROM.

Thanks in advance,
R

Hello.
Have you tried downloading both Bitmap Drawer Files demos from here?

OK cheers, will have a check.

Hey unity-control,

Did you get this working on a ILI9341 display?
Would you like to share an example?

Thanks!

Hello,

I've had a look at implementing PNG/GIF support and the file formats are reasonably easy to parse, the problem is the compression that is used to reduce the file size. Decompressing would take a fair amount of ROM and RAM and on a lot of embedded targets would actually eat up more resources then just using a bitmap. If your using a few files then it might start to make more sense.

I've made a start but I can't promise it will get finished anytime soon unless there is a real need for this.

A step in the right direction might be another component to perform the compression and decompression and then we can also potentially use it in other places.

Sounds great!

But is there a simple example for a ILI9341 display that I can look (and learn) at (from)?
