Custom RMT interrupt handler in the current master.
There seem to have been undocumented changes in the RMT driver implementation. The documentation states: When calling rmt_driver_install() to use the system RMT driver, a default ISR is being installed. In such a case you cannot register a generic ISR handler with rmt_isr_register(). Ok so the steps...

C++ Atomics implemented?
Hy,
Is the <atomic> header usable and performant or do I have to use <stdatomic.h>.
If <atomic> is not available is there some documentation with examples for <stdatomic.h>? I have already understood what all the different memory orders do.

Hi ESP_Angus,
Don't point links to files in the master branch as it changes. (The line is not correct anymore.)

Re: spi_flash size warning
I had already selected the correct option and flashed the app multiple times. Reflashing the bootloader fixed the issue.

Re: CMake with CLion - working!
I don't know if it helps but I created a [template project for clion](https://gitlab.feather.ink/raldone01/es ... t-template) which works for windows without setting environment variables. (ESP-IDF v4)

Malloc and free threadsafe?
I want to access I2C functionality from multiple tasks. My current plan is to have one task communicate with the I2C driver (the handler task) and pass the i2c_cmd_handle_t s which are created by different tasks to the handler task. Once the handler is done it should free the i2c_cmd_handle_t s. So ...
