ESP32-S3 defines two additional general use pins in
ports/espressif/peripherals/esp32s3/pins.h, for which
support is missing in the microcontroller module HAL.
esp_ping_new_session can fail, particularly if ping is called quickly
many times in succession.
This is because `esp_ping_new_session` has to do a bunch of stuff
including creating a task and a socket. Calling `esp_ping_delete_session`
doesn't clean up these resources immediately. Instead, it signals the
task to clean up resources and exit 'soon', but 'soon' is defined as 1
second.
When the calls are frequent, the in-use sockets and tasks fill up
available slots—I didn't actually check which resource gets used
up first.
With this change, the ping call will raise an exception instead of
continuing with a call to esp_ping_start that crashes.
Closes#5980 based on my testing on an ESP32S3-N8R2.
Fixes polling thread looping forever hangs preventing new connections.
Don't lose listening sockets on mp resets and re-init.
Keep better separation of "system" and "user" sockets.
Track socket states to prevent re-use of sockets before closed.
Close REST socket when transaction completes. No post-init.
Remove unnecessary state flags.
It now handles deinit, never_reset and sharing tracking. PWM
now runs in the WAIT state as well during a time.sleep().
_reset_ok() was removed because it was called in one spot right
before deinit().
Some PWMOut were also switched to a bitmap for use instead of
reference count. That way init and deinit are idempotent.
Fixes#6589. Fixes#4841. Fixes#4541.
Pre-commit: Fixed compilation error for other ESP32C3/ESP32S3/ESP32H2 boards
Review comment: Removed the self->pin NULL check
Review comment: Using raise_ValueError_invalid_pin when adc_index is not ADC_UNIT1 for ESP32
Review comment: Optimized the code to set data in buffer from DMA results
Fix: For ESP32C3 boards continuing collecting samples after channel mismatch as DMA runs in alternating UNIT mode
Fix: For ESP32S3 and ESP32H2 setting conversion mode to type2
