Daniel P. Carvalho 1b172fb8d2 drivers/sensors: add Microchip TC74 temperature sensor driver
Add support for the Microchip TC74 digital temperature sensor using the
Sensor Driver Framework (uORB). The TC74 is an 8-bit I2C temperature
sensor with a measurement range from -40C to +125C and a resolution
of 1C.

The driver registers as a uORB topic (/dev/uorb/sensor_temp<n>) and
polls on the low-priority work queue. It supports dynamic interval
configuration and automatically enters low-power standby mode when
the topic is deactivated.

Validated against a real TC74A5-3.3 on a custom STM32H743BI board.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

Contributing

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
