Feather Huzza RAM and Touch Screen

Post by cawhitley »

How much app-usable RAM is free in the Feather Huzza? I want to use a SPI-based touch screen, and want to make sure that the CPU has enough free RAM to manipulate the display graphics, as needed.

Has anyone every hooked the Feather Huzza to a 2.8" or larger touch screen? Your thoughts?

Thanks.

Thanks for the info. FYI, the display that I will be testing has a ILI9325 chip with it, and their web page provides a link for software examples for Arduino. Since I posted my request, I compiled that software for the ATmega2560, and it yielded a RAM usage of under 300 bytes, so it seems that for the display part (ignoring the SD card attachment part), the RAM usage is not too bad.
