For a new project I'm going to use this Newhaven Display with a custom ESP32-based board.
I'm reading the datasheet but I still have few questions I cannot answer by myself.
-
they suggest to use an sd-card (like in their Arduino shield) that is connected to the same SPI bus. It's not clear to me if is Arduino that reads the files on the sd-card and transfers the data to the display, or it just tells the display which file to read. I'm asking this because if the former, can I use the internal flash of ESP32 to provide the desired images?
-
what is (at the moment) the recommended library to use? I see there is an "official" repository with some code, but they claim it's not their code (but writtend by FTDI/Bridgetek). Looking on github I found several repositories for Arduino and FT813... before trying one-by-one, I'd like to know if anyone already used them.
-
the display allows to use SPI, DSPI or even QSPI. I need to show a couple of static images (like buttons, LEDs, etc...) and a simple XY scatter graph update in real-time (but very slowly, say about 1 sps). Do you think I really need anything faster than the default SPI?
Thanks in advance!
