+DAC API
+********
+
+-----------------------------
+
+Description
+------------
+
+ESP32 has two 8-bit DAC (digital to analog converter) channels, connected to GPIO25 (Channel 1) and GPIO26 (Channel 2).
+The DAC driver allows these channels to be set to arbitrary voltages.<br The DAC channels can also be driven with DMA-style written sample data, via the I2S driver when using the “built-in DAC mode”.
+
+ESP32 DAC output voltage range is 0-Vdd (3.3 V), the resolution is 8-bits
+
+
+-----------------------------
+
+Function
+---------
+
+machine.DAC(pin)
+>>>>>>>>>>>>>>>>>
+
+| **Description:** 　　
+|   Pin argument defines the gpio which will will be used as dac output
+|   *Note: Only GPIOs 25 and 26 can be used as DAC outputs*
+|   
+
+| **Parament:**
+|   **pin:** The pin argument can be given as pin number (integer) or the machine.Pin object
+
+| **Example:**
+.. code:: python
+
+    import machine
+
+    dac = machine.DAC(machine.Pin(26))
+    dac.write(128)
+
+write(value)
+>>>>>>>>>>>>>>>>>

+| **Description:** 　　
+|   Set the DAC value
+|   *Note: The value of 255 sets the voltage on dac pin to 3.3 V
+|   
+
+| **Parament:**
+|   **value:** DAC vaule.Valid range is: 0 - 255
+
+| **Example:**

+ESP32 RMT peripheral is used for very precise timing ( +/- 50 ns ).
+Up to 8 Neopixel strips can be used, 1~1024 pixels each.

+M5Stack BTC Module
+==================
+
+DESCRIPTION
+-----------
+
+The M5Stack BTC Module is a base including DHT12 module which can detect
+temperature and humidity. Your M5Stack Core board can stay as a small
+displayer(like a small TV or a small IOT central contronller) after
+adding this BTC Module. Absolutely, it is more easier to charge M5Stack
+Core via Type-C Cable after adding this BTC Module.
