Not offhand... but it's a standard ILI9341 SPI LCD, the code should be compatible with a fair amount of other ones like it as well.

Re: ESP32 Launch Event & Demos

I was there, it was all in Chinese, sorry :) We'll make sure to release the demos in time. You know how it goes with demos: even if they work, under the hood they often are a rushed mess that works around all the bugs you can't fix in time... we'll need some time to make everything presentable.

Re: An example of BLE?

Not yet, sorry. The bluetooth code still needs integration into the ESP-IDF.

Re: SPI boot/pin mux config question

It's configurable by efuses. The effect of routing high-speed signals over the GPIO matrix is a latency of 2 clock cycles, iirc. It's somewhere in the techdocs, if memory serves.

Re: How does Flash Encryption (aka Secure Boot) work?

They're both aspects of the same thing, although you can use them separately. (Not sure how much sense that would make, though.) We're preparing documentation on that, at least an abstract of the hardware will be probably in the next techdoc.

Re: SPI boot/pin mux config question

It can boot from HSPI as well, if I recall correctly. Plus, you have the option of remapping pins after boot. I think you can even remap some _before_ boot, by using the efuses, but that's not documented yet.

Re: Interest in developer preview?

ESP-IDF for the ESP8266: Maybe. It should be pretty easy to take the existing binary libraries and put them into the ESP-IDF framework, that's not an issue. To make support for the ESP8266 in ESP-IDF as full-featured as the ESP32 is, is a different story. We're not sure what the plans are with regar...

Re: What is the "Capacitive touch sensor" and the "LCD interface"

WiiFive is right about the capacitive touch screen display. The LCD interface is basically an 8, 16 or 24-bit parallel interface connected to DMA that makes it very fast to upload data to parrallel LCDs or other peripherals. (It's actually part of one of the I2S ports.)

Re: OpenOCD and hardware debugger support

Rudi: That's in software and uses 2 extra pins :) the J-link idea is that everything can happen over JTAG.

By the way, parts of the register level documentation ('parts of' because we're still working on it) have been released by now, see http://esp32.com/viewtopic.php?f=5&t=188

Re: VDET control pins

Well, they belong to the RTC power domain, which means that the devices that fall under the RTC can control them. It means e.g. that they can be used as ADC pins and that the ULP coprocessor can read them. Apart from that, they can also be used as normal GPIOs and when the CPU is on, they can be rou...
