+# esp32-ds18b20
+
+## Introduction
+
+This is a ESP32-compatible C component for the Maxim Integrated DS18B20 Programmable Resolution 1-Wire Digital Thermometer device.
+
+It supports multiple devices on the same 1-Wire bus.
+
+It is written and tested for v2.1 and v3.0 of the [ESP-IDF](https://github.com/espressif/esp-idf) environment, using the xtensa-esp32-elf toolchain (gcc version 5.2.0).
+
+## Dependencies
+
+Requires [esp32-owb](https://github.com/DavidAntliff/esp32-owb).
+
+## Example
+
+See [esp32-ds18b20-example](https://github.com/DavidAntliff/esp32-ds18b20-example) for an example that supports single and multiple devices on a single bus.
+
+## Features
+
+In cooperation with the underlying esp32-owb component, this component includes:
+
+ * External power supply mode (parasitic mode not yet supported).
+ * Static (stack-based) or dynamic (malloc-based) memory model.
+ * No globals - support any number of DS18B20 devices on any number of 1-Wire buses simultaneously.
+ * 1-Wire device detection and validation, including search for multiple devices on a single bus.
+ * Addressing optimisation for a single (solo) device on a bus.
+ * CRC checks on temperature data.
+ * Programmable temperature measurement resolution (9, 10, 11 or 12-bit resolution).
+ * Temperature conversion and retrieval.
+ * Separation of conversion and temperature retrieval to allow for simultaneous conversion across multiple devices.
+
+## Documentation
+
+Automatically generated API documentation (doxygen) is available [here](https://davidantliff.github.io/esp32-ds18b20/index.html).

+## Roadmap
+
+The following features are anticipated but not yet implemented:
+
+ * Concurrency support (multiple tasks accessing devices on the same bus).
+ * Alarm support.
+ * EEPROM support.
+ * Parasitic power support.
