M3ARM interfacing to monitor

Development Boards MicroMod
1

Hi all,

I’m using mcbstm32 evaluation board from Keil. Its using a M3 cortex arm.

Intending to make a video game or something like that.

So first was wondering if its possible to interface it to PC monitors?

Any reading materials?

Thanks in advance

Here are the specs:

Sure google tells us that others has done it…

But I don’t think it will be easy.

ya… i search through some of them too… but none really gives me an idea on how to go about doing it.

was hoping someone here will give me a hint on how to start. like what to read or what to understand.

i want to do something like this guy… but first need to start outputting the graphics from the ARM to monitor

Using a Picaso would have to be the easiest way to go:

Then you could concentrate on programming your game.

There’s a video showing Picaso’s capabilities here:

WARNING: I recommend you turn the soundtrack off :wink:

Hi,

thanks for the suggestion. have read about the picaso too… and also realise most graphic processing uses an additional proc to process the graphic…

but my main objective is actually to test out the capability or functionalilty of this mcbstm32 eval board. so would like to put this board to test and see if its able to output graphics out…

Thanks

Ultimately it depends on which evaluation board you have. Higher performance graphics require things like frame buffers. Considering computer screens rarely do less than 640x480, and if you did the lowest resolution (8-bit color), you’ll need to keep a frame buffer that is 640x480x8 bytes large. You can write directly to the screen, but you are going to get a lot of flicker as the frame rate will be very low. You will probably need hand-optimized bit-blit and output routines written in assembly. Also remember that you can’t just write the output to the screen and expect it to stay there, you have to take care of things like H-Sync and V-Sync, refresh rate, etc.

If you have the board with the external SRAM, then you can probably do it, but don’t expect X-Box…

If you want a suggestion on where to start, pick up the Linux sources and start looking through the low level Kernel video drivers. Specifically pick out an ARM set that supports video from the arch directories.
