available resolution?

[noob]

background: i’ve never done anything with video signals. i have a little elec.engr. education at present.

what resolutions are available for the video experimenter? all the example images and videos show output at a very low resolution. it reminds me of my parents’ old Magnavox Odyssey2.

also, is it capable of outputting color or just b&w?

The resolution is limited by the amount of memory in the ATmega328 microcontroller. It only has 2K of SRAM, so 1-bit depth (monochrome) resolution of 128×96 consumes 1.5K. You can go a little higher, like 136×96 or maybe 136×104, but you need to leave some SRAM for your program variables, stack, etc.

No color, only monochrome. This hardware cannot generate the analog waveforms required for color.

Hi,

What would be the max available resolution using the seeeduino mega?

I’ve looking for extra memory shields and found some… is it possible to use them along with the VE in order to increase resolution?

thank you.

You can go up to 192×128 or maybe higher with the Seeeduino Mega.

No, an external memory expansion would not help. You can’t access the memory fast enough. The video generation code is written in assembly, and it can’t be made any faster.
