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...

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.)

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

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...

Unfortunately, I have not seen that functionality in the Xtensa core we use. The default way to do things on our core is to halt the processor and then feed instructions into the core instruction pipeline, which obviously means the CPU can't run at the same time.

They are general RTC-domain inputs. You can use them as GPIO (well, they're input only, so GPI) or connect them to an ADC.

ESP32 technical Reference Manual This is the first version of the document, containing info about System,Memory, Reset and Clocks, and a register-level description of the IO mux, GPIO matrix, LED PWM controller, remote controller peripherial, pulse counter, 64-bit timers, watchdog timers and the AE...

Yes, OpenOCD is being worked on very hard, I just finished re-basing the tree on the latest upstream version. At the moment, it supports standard gdb debugging, and I just got FreeRTOS support working again as well, so you can basically switch between individual threads in gdb. Multicore support doe...

Rudi: Just checked the techdocs: the ESP32 has 2xI2C.

Okay, we released the SDK. As I said, this is just a developer preview and we don't want to create any false expectations here: please assume the code is work-in-progress and we'd appreciate it if it didn't get too much publicity yet. With that said, it gives a very good indication where we want to ...
