Re: Small ESP32 Modul ( all include in new ESP32-PICO )

btw "some secret magic"
yes this are given in this "psram" theme in many ways :lol:
you have only to find it out and believe in your own thinking and own making.
best wishes

last btw:
one magic is in SD Card + PSRAM on a PICO-D4
but this is an other theme :mrgreen:

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

yes - only cs is pulled up with 10k. clk is like it is. btw caused clk need separate pin Sharing CLK may not work b/c CLK to PSRAM is routed through GPIO matrix. Need to clock in one or two extra cycles, depending on the freq. the psram theme is a long theme :) keep us updated to your tiny tiny pico...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

Hey rudi... the CLK and DATA pin can share an IO (GPIO10) ? How is that possible? Cheers, Seon unexpectedmaker.com damn... now the confuse begins from start again :) want edit it but to late - you read my last (deleted) post :) you can share only the data pins between psram and flash. for flash you...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

You have to modify the esp-idf/components/esp32/spiram_psram.c , (I'll do it in the next MicroPython repository update), to enable psRAM initialization for ESP32-PICO-D4 and rebuild the firmware. See this for instructions. The correct pin mapping should be like this (latest response from esp-idf te...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

Hey Rudi.. I'd like to revive this thread! Firstly, thanks for all of your work on getting PSRAM working on the PICO-D4! What are the final pin mappings you used for rev1 silicon? Hi https://esp32.com/viewtopic.php?f=2&p=18439#p17627 https://esp32.com/viewtopic.php?f=2&p=18439#p18431 I have a board...

Re: Routing/bridging

@ tomikpik
I dig up the cellar.
after few time and try#s, there comes perhabs a custom proof of concept with ETH and Wifi after the summer vacation.
still in tests and I am satisfied so far. I use it for a LAN to WIFI bridge.
best wishes
