Sprite, my interest in ESP chips is mostly for "hackish" DIY tinkering purposes, and I know you are very well placed to understand this niche crowd, but to know as well that even real products developpers could meet them on some features that look dispensable at first (like repurposing I2S as a gene...

Thanks for asking. Again, USB host+device would be great as long as CPU overhead is minimal (but in the meantime, I'd still be glad if you could share your experimental RMT implementation of Host USB 1.1) And the never-ending and boring MORE list ; - more "no wait-state" DRAM + default 4MB of PSRAM ...

Yes, this is the perfect breadboard module : all ESP32 pins available, borderless, with 2 breadboard rows accessible on each side.

Please Espressif, release it for us, mere mortals too !

@Sprite: ok sorry, with the delay between writes to the same register, and the "nops" sequence, it looked very similar to the code examples previously provided as a workaround (I hope the bug has been fixed in the new revision though).

In psxcontroller.c , I can see you still use some delay (with a series of nops in asm) between gpio writes as a workaround to prevent discarded writes in fast, subsequent accesses to the same register. (alternative register addresses were provided in the "ESP32 bugs and workarounds" document, but i ...

Thanks for your consideration Sprite, and we know that cnlohr is not kidding at all : he just needs another carrier for TV transmission (or GSM, GPS, fibre channel, VR lighthouses or whatever) so while you're at it, for the same price, make it 10 x I2S, please ! with dedicated CPU cores, and a recon...

@Franco : for your and other readers' information, Cnlohr already did his own share of reverse-engineering to implement a working, bit-banged "usb device" on ESP8266 with GPIO code in assembly and clever tricks (but even pushing it to the limits, hardware latencies prevented full-speed usb). A look ...

Now that ESP32 is out, maybe you could tell us more now. Some new I2S functionnalities are mentionned in the datasheet (like BT PCM), but besides audio applications, I was wondering about I2S ports max "bit-bang" capabilities as very-high-speed serial inputs/outputs ... For it's "TV-broadcast" exper...
