More Dynamic Memory

Postby Reefhermit » Thu Dec 14, 2017 9:27 pm

Is it possible to get more dynamic memory? I need bout 0.75-1 Meg for the arrays.

In general; any devboard which has either the ESP32-Wrover module or a bare ESP32 with an extra PSRAM chip should give you 4MiB of dynamic memory.

That’s what I thought, but it doesn’t show up on the Arduino IDE. And when I try to run the large array code I run out of memory. Can you advise how to use the SPI Ram?

Ah, sorry, I didn't see you posted this on the Arduino forum... that is a bit outside my area of expertise, I'm afraid.
