 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. |

The new ESP32-S3-PICO-1 looks very interesting with its internal 8M Octal PSRAM option Edited 2024-03-16 19:48 by knivd |

I've played with it but the issue is that the PSRAM and the external flash which holds the program share the same SPI bus. This means that the effective bandwidth from the PSRAM is limited and can be conflicted. The various commercial demos tend to have very low refresh rates for the displays - in one case just 12FPS. If you use a display small enough to keep the framebuffer in internal RAM then it can work very well but the PSRAM isn't the panacea that it, at first, appears |

Yes, in that sense all ESP32xxx products are the same - SPI bus shared across all critical sub-systems. This one is interesting in with its level of integration, which translates into space saved on board Edited 2024-03-16 20:03 by knivd |
