[GitHub] [incubator-nuttx-apps] diegoherranz opened a new pull request #717: hdc1008_demo: set intial measurement mode

diegoherranz opened a new pull request #717:
URL: https://github.com/apache/incubator-nuttx-apps/pull/717


   ## Summary
   No mode was set before the first read by the app.
   The first time the app was run, it worked properly, reading temperature and humidity on the first read(). But subsequent reads returned humidity only since that was last mode set up.
   
   First run of the app:
   ```
   nsh> hdc1008
   Temperature and humidity
   ========================
   data=20.54 56.9
   
   Temperature and humidity (ioctl)
   ================================
   t=20.54, h=56.9
   
   Temperature, 11 bit resolution
   ==============================
   data=20.78
   
   Temperature, 14 bit resolution
   ==============================
   data=20.69
   
   Humidity, 8 bit resolution
   ===========
   data=57.1
   
   Humidity, 11 bit resolution
   ===========
   data=56.9
   
   Humidity, 14 bit resolution
   ===========
   data=56.9
   ```
   
   Second run of the app:
   ```nsh> hdc1008
   Temperature and humidity
   ========================
   data=56.9
   
   Temperature and humidity (ioctl)
   ================================
   t=2684430.32, h=56.9
   
   Temperature, 11 bit resolution
   ==============================
   data=20.71
   
   Temperature, 14 bit resolution
   ==============================
   data=20.72
   
   Humidity, 8 bit resolution
   ===========
   data=57.3
   
   Humidity, 11 bit resolution
   ===========
   data=56.9
   
   Humidity, 14 bit resolution
   ===========
   data=56.9
   ```
   
   ## Impact
   hdc1008 app only
   
   ## Testing
   Tested on custom board.
   Now, every run of the app returns temperature and humidity on the first read
   
   ```
   nsh> hdc1008
   Temperature and humidity
   ========================
   data=20.94 56.0
   
   [...]
   
   nsh> hdc1008
   Temperature and humidity
   ========================
   data=20.97 55.9
   [...]
   ```
   
   Thanks!
