 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

you may consult the Picomite user manual, there are descriptions of use-cases for PSRAM with pros and cons. 73 de OE1HGA, Gerald |

It all depends, as do a lot of things. :) PSRAM gives you a very big RAM area but any programs you write that use it will, of course, only run on platforms that have it. If you want to run software written for the Pico or Pico 2 then you don't need PSRAM as neither of those platforms has it. As it's RAM it's main use is probably when you need lots of of temporary data storage. Your maximum program size isn't increased. This is why I'm not over concerned about problems I'm having with it on GAP1. That's designed for playing games and unless someone starts to write games that need PSRAM then it's merely a "nice to have".

I'm expecting only to run on RP2350. Heap has been my issue so far. PicoDB will run with LCD on a Pico2, Pico2-Zero, Pico2 clone, and WeAct RP2350B module, but on Peter's Pico2 HDMI board, I've had to cut way back on some array sizes, and also move from 800x600 to 640x480 in resolution. If speed doesn't become a issue (and I think it doesn't look like it will be), then if PSRAM can be used for heap, then largish (for microcontrollers) databases will be possible.
