HTU21D-sensor-controller

The sensor controller is designed to work with the HTU21D sensor,using the Sensor Controller Engine of CC2640R2F MCU.

  • Project name: HTU21D sensor
  • Project file: HTU21D_sensor.scp
  • Operating system: TI-RTOS
  • Target chip: CC2640R2F, package QFN48 7x7 RGZ
  • I2C0_SCL - pin 11; I2C0_SDA - pin 10

How to generate project files.

In order to generate all project files, you must:

  • Launch “Sensor Controller Studio” (SCS) using the HTU21D_sensor.scp project file.
  • In the SCS program, click on the “Code Generator” button. SCS will create a scif_files folder (if it did not exist before) and generate all the necessary files in it (except for the readme file).
  • The file “scif_htu21d_how_to_use.html” contains information on using the controller.

Software tools:

  • Sensor Controller Studio v2.7.0.155

Debugging:

  • The project was debugged on the CC2640R2-LAUNCHXL debug board.

Connection to CC2640R2-LAUNCHXL board:

  • HTU21D / pin1 - SDA / DIO5 + PULUP 10K
  • HTU21D / pin2 - GND
  • HTU21D / pin5 - 3.3V
  • HTU21D / pin6 - SCL / DIO4 + PULUP 10K
