@brief Take an ADC1 reading from a single channel.
@note ESP32:
When the power switch of SARADC1, SARADC2, HALL sensor and AMP sensor is turned on,
the input of GPIO36 and GPIO39 will be pulled down for about 80ns.
When enabling power for any of these peripherals, ignore input from GPIO36 and GPIO39.
Please refer to section 3.11 of ‘ECO_and_Workarounds_for_Bugs_in_ESP32’ for the description of this issue.
As a workaround, call sar_periph_ctrl_adc_oneshot_power_acquire() in the app. This will result in higher power consumption (by ~1mA),
but will remove the glitches on GPIO36 and GPIO39.

@brief Uninstall Ethernet driver
@note It’s not recommended to uninstall Ethernet driver unless it won’t get used any more in application code.
To uninstall Ethernet driver, you have to make sure, all references to the driver are released.
Ethernet driver can only be uninstalled successfully when reference counter equals to one.
@brief Increase Ethernet driver reference

@brief Cancel an ongoing HTTP request. This API closes the current socket and opens a new socket with the same esp_http_client context.
@brief This function must be the last function to call for an session.
It is the opposite of the esp_http_client_init function and must be called with the same handle as input that a esp_http_client_init call returned.
This might close all connections this handle has used and possibly has kept open until now.
Don’t call this function if you intend to transfer more files, re-using handles is a key to good performance with esp_http_client.
@brief Close http connection, still kept all http request resources
@brief Delete http request header
@brief This function need to call after esp_http_client_open, it will read from http stream, process all receive headers
@brief Process all remaining response data
This uses an internal buffer to repeatedly receive, parse, and discard response data until complete data is processed.

@brief Check response data is chunked
@brief Checks if entire data in the response has been read without any error.
@brief This function will be open the connection, write all header strings and return
@brief Invoke this function after esp_http_client_init and all the options calls are made, and will perform the
transfer as described in the options. It must be called with the same esp_http_client_handle_t as input as the esp_http_client_init call returned.
esp_http_client_perform performs the entire request in either blocking or non-blocking manner. By default, the API performs request in a blocking manner and returns when done,
or if it failed, and in non-blocking manner, it returns if EAGAIN/EWOULDBLOCK or EINPROGRESS is encountered, or if it failed. And in case of non-blocking request,
the user may call this API multiple times unless request & response is complete or there is a failure. To enable non-blocking esp_http_client_perform(), is_async member of esp_http_client_config_t
must be set while making a call to esp_http_client_init() API.
You can do any amount of calls to esp_http_client_perform while using the same esp_http_client_handle_t. The underlying connection may be kept open if the server allows it.
If you intend to transfer more than one file, you are even encouraged to do so.
esp_http_client will then attempt to re-use the same connection for the following transfers, thus making the operations faster, less CPU intense and using less network resources.
Just note that you will have to use esp_http_client_set_** between the invokes to set options for the following esp_http_client_perform.

@brief Set redirection URL.
When received the 30x code from the server, the client stores the redirect URL provided by the server.
This function will set the current URL to redirect to enable client to execute the redirection request.
When disable_auto_redirect is set, the client will not call this function but the event HTTP_EVENT_REDIRECT will be dispatched giving the user contol over the redirection event.
@brief Set http request timeout
@brief Set URL for client, when performing this behavior, the options in the URL will replace the old ones
@brief Set http request user_data.

- If duty type is set to MESH_PS_DEVICE_DUTY_DEMAND, the running active duty cycle is dev_duty specified by the users.
- In a mesh network, devices are typically working with a certain duty-cycle (transmitting, receiving and sleep) to
reduce the power consumption. The running active duty cycle decides the amount of awake time within a beacon interval.
At each start of beacon interval, all devices wake up, broadcast beacons, and transmit packets if they do have pending
packets for their parents or for their children. Note that Low-duty-cycle means devices may not be active in most of
the time, the latency of data transmission might be greater.

@brief Set the network duty cycle, duration and rule
- The range of nwk_duty values is 1 to 100. The default value is 10.
- nwk_duty is the network duty cycle the entire network or the up-link path will use. A device that successfully
sets the nwk_duty is known as a NWK-DUTY-MASTER.
- duration_mins specifies how long the specified nwk_duty will be used. Once duration_mins expires, the root will take
over as the NWK-DUTY-MASTER. If an existing NWK-DUTY-MASTER leaves the network, the root will take over as the
NWK-DUTY-MASTER again.
- duration_mins = (-1) represents nwk_duty will be used until a new NWK-DUTY-MASTER with a different nwk_duty appears.
- Only the root can set duration_mins to (-1).
- If applied_rule is set to MESH_PS_NETWORK_DUTY_APPLIED_ENTIRE, the nwk_duty will be used by the entire network.
- If applied_rule is set to MESH_PS_NETWORK_DUTY_APPLIED_UPLINK, the nwk_duty will only be used by the up-link path nodes.
- The root does not accept MESH_PS_NETWORK_DUTY_APPLIED_UPLINK.

- Set how many beacons with CSA IE will be sent before changing a new channel
- Enable the channel switch function
@brief Cause the root device to give up (waive) its mesh root status
- A device is elected root primarily based on RSSI from the external router.
- If external router conditions change, users can call this API to perform a root switch.
- In this API, users could specify a desired root address to replace itself or specify an attempts value
to ask current root to initiate a new round of voting. During the voting, a better root candidate would
be expected to find to replace the current one.
- If no desired root candidate, the vote will try a specified number of attempts (at least 15). If no better
root candidate is found, keep the current one. If a better candidate is found, the new better one will
send a root switch request to the current root, current root will respond with a root switch acknowledgment.
- After that, the new candidate will connect to the router to be a new root, the previous root will disconnect
with the router and choose another parent instead.

behind the former loaded buffer. But when all the DMA buffers have been loaded, no more data can be preload then, please
check the bytes_loaded parameter to see how many bytes are loaded successfully, when the bytes_loaded is smaller than
the size, it means the DMA buffers are full.

@note The new created I2S channel handle will be REGISTERED state after it is allocated successfully.
@note When the port id in channel configuration is I2S_NUM_AUTO, driver will allocate I2S port automatically
on one of the I2S controller, otherwise driver will try to allocate the new channel on the selected port.
@note If both tx_handle and rx_handle are not NULL, it means this I2S controller will work at full-duplex mode,
the RX and TX channels will be allocated on a same I2S port in this case.
Note that some configurations of TX/RX channel are shared on ESP32 and ESP32S2,
so please make sure they are working at same condition and under same status(start/stop).
Currently, full-duplex mode can’t guarantee TX/RX channels write/read synchronously,
they can only share the clock signals for now.
@note If tx_handle OR rx_handle is NULL, it means this I2S controller will work at simplex mode.
For ESP32 and ESP32S2, the whole I2S controller (i.e. both RX and TX channel) will be occupied,
even if only one of RX or TX channel is registered.
For the other targets, another channel on this controller will still available.

Queries a stream buffer to see how much data it contains, which is equal to

@cond !DOC_EXCLUDE_HEADER_SECTION
@cond
Queries a stream buffer to see if it is empty. A stream buffer is empty if
it does not contain any data.
Queries a stream buffer to see if it is full. A stream buffer is full if it
does not have any free space, and therefore cannot accept any more data.
Receives bytes from a stream buffer.
For advanced users only.
An interrupt safe version of the API function that receives bytes from a
stream buffer.
Resets a stream buffer to its initial, empty, state. Any data that was in
the stream buffer is discarded. A stream buffer can only be reset if there
are no tasks blocked waiting to either send to or receive from the stream
buffer.
Sends bytes to a stream buffer. The bytes are copied into the stream buffer.
For advanced users only.
Interrupt safe version of the API function that sends a stream of bytes to
the stream buffer.
A stream buffer’s trigger level is the number of bytes that must be in the
stream buffer before a task that is blocked on the stream buffer to
wait for data is moved out of the blocked state. For example, if a task is
blocked on a read of an empty stream buffer that has a trigger level of 1
then the task will be unblocked when a single byte is written to the buffer
or the task’s block time expires. As another example, if a task is blocked
on a read of an empty stream buffer that has a trigger level of 10 then the
task will not be unblocked until the stream buffer contains at least 10 bytes
or the task’s block time expires. If a reading task’s block time expires
before the trigger level is reached then the task will still receive however
many bytes are actually available. Setting a trigger level of 0 will result
in a trigger level of 1 being used. It is not valid to specify a trigger
level that is greater than the buffer size.
Queries a stream buffer to see how much free space it contains, which is
equal to the amount of data that can be sent to the stream buffer before it
is full.
INCLUDE_xTaskAbortDelay must be defined as 1 in FreeRTOSConfig.h for this

interrupts disabled for an extended period resulting in tick interrupts having
been missed.
Determines if pxTicksToWait ticks has passed since a time was captured
using a call to vTaskSetTimeOutState(). The captured time includes the tick
count and the number of times the tick count has overflowed.
@brief Create a new task that is pinned to a particular core
@brief Creates a pinned task where its stack has specific memory capabilities
@brief Create a new static task that is pinned to a particular core
INCLUDE_xTaskDelayUntil must be defined as 1 for this function to be available.

Waits for a direct to task notification to be pending at a given index within
an array of direct to task notifications.
@brief Get the current core ID of a particular task
@brief Get the handle of the task currently running on a certain core
NOTE: This function takes a relatively long time to complete and should be
used sparingly.
xTaskGetIdleTaskHandle() is only available if
INCLUDE_xTaskGetIdleTaskHandle is set to 1 in FreeRTOSConfig.h.
@brief Get the handle of idle task for the given core.
@brief Get the next task using the task iterator.
@return The count of ticks since vTaskStartScheduler was called.
@return The count of ticks since vTaskStartScheduler was called.
@cond !DOC_EXCLUDE_HEADER_SECTION
Resumes scheduler activity after it was suspended by a call to
vTaskSuspendAll().
INCLUDE_xTaskResumeFromISR must be defined as 1 for this function to be
available. See the configuration section for more information.
@cond !DOC_EXCLUDE_HEADER_SECTION
Returns the time in ticks at which the timer will expire. If this is less
than the current tick count then the expiry time has overflowed from the
current time.
Returns the period of a timer.
Queries a timer to determine if it is an auto-reload timer, in which case the timer
automatically resets itself each time it expires, or a one-shot timer, in
which case the timer will only expire once unless it is manually restarted.
Simply returns the handle of the timer service/daemon task. It it not valid
to call xTimerGetTimerDaemonTaskHandle() before the scheduler has been started.
Queries a timer to see if it is active or dormant.
Used to defer the execution of a function to the RTOS daemon task (the timer
service task, hence this function is implemented in timers.c and is prefixed
with ‘Timer’).
Used from application interrupt service routines to defer the execution of a
function to the RTOS daemon task (the timer service task, hence this function
is implemented in timers.c and is prefixed with ‘Timer’).
