Is the ulp involved?
No
Is the main core really in deep sleep?
Yes
what about the power consumption while [esp_deep_sleep_enable_ext0_wakeup()]?
~20uA I think

Yes this is probably not final version of the driver. Registers are beautiful though

Interested in the i2s dac output resolution

Any update on:

ULP binutils
ADC characterization
Temp sensor
Hall sensor usage guide
PWM
PID
Audio libraries/examples
Expanded support for qio flash mode

Rev 1 silicon
PSRAM

RAM optimization goals/timeline

There is only one rtc interrupt so it has to be shared (similar to gpio interrupt). You could implement an isr service like gpio to have separate callbacks per pin. Arduino already does this so you could use that code.

Right I guess you could request getter functions for the semaphores or a compare function.

Yes I believe ringbuf library is made by @esp_sprite Once you receive the matching handle you can compare it to the handles you think it could be to figure out which member to operate on. But consider: http://www.freertos.org/Pend-on-multiple-rtos-objects.html#alternative_design_pattern which may or...
