Today is code time also! And a continuation from my previous sample.
Yesterday I show how to read a static value: the battery. And, when you work with a device like a drone there are other important values to analyze in order to send commands to the drone. Like altitude, position, time of flight etc.
So, based on yesterday sample, I’ll show how to create a simple Python app, that will display the accelerator X value. In the following video you can see the how the value start “static” during the 1st couple of seconds, until I pickup the device and I moved it around.
Important: don’t blame me about the low battery. Playing with the drone drains the battery very fast!
Once again, the code is very straight forward. It runs a loop furing 10 seconds, showing the battery and accelX information.
Just as a reminder, this is the information we get from the drone:
As you can read, all the information is condensed in a single line and we can split and get:
- templ (temperature low)
- temph (temperature high)
- tof (time of flight)
- h (height)
- b (battery)
- baro (barometer)
