drivers/tmp117: TMP117 driver

[leocordier]

Contribution description

This pull request add a basic driver for the TMP117 sensor with the following capabilities:

• tmp117 initialization
• tmp117 configuration : update the conversion mode, cycle and averaging parameters
• tmp117 temperature reading : with a result in centi-degrees
• check if tmp117 temperature measure is ready

This pull request add a driver in the drivers folder and a test in the test/drivers folder

Testing procedure

The basic test that i wrote, initialize the sensor with default paramaters and i2c address.
After the initialization, it display the measured temperature every 1.5 seconds.

If the initialization or the temperature reading fail, it displays anb error.

Thanks @leocordier.

Could you also check if SAUL support would be easy to add? See https://docs.riot-os.org/advanced_tutorials/device_drivers/#saul

Hello, i'm starting to add SAUL support to the TMP117 but i'm not familiar with the SAUL system.
I've added a tmp117_saul.c file with function which comply with the saul_read() format and i've registered this function in a saul_driver_t structure.

However, i don't understand how my device can be initialized only with saul.

SAUL-compatibel sensors are/can be auto-initialized. See https://github.com/RIOT-OS/RIOT/blob/master/drivers/saul/init_devs/auto_init_si70xx.c and https://github.com/RIOT-OS/RIOT/blob/master/drivers/saul/init_devs/init.c#L342.

The main driver Makefile must look like this: https://github.com/RIOT-OS/RIOT/blob/master/drivers/si70xx/Makefile

Now, when the saul_default module is used, any SAUL compatible driver for your board, will automatically be initializes.

Does this help?

[leocordier]

Yep, thanks i will look into it

Here it is, i've tested the saul support for the tmp117 and it works ! 🙂
