Auto altitude control with a barometer

Hi,all
I was thinking about building a firmware to hold the altitude autonomously only with the aid of the embedded barometer sensor. That is, when I switch on the crazyflie, it flies to the designated altitude and hover on the position. I will not need any PC client or the crazyradio. Is that even possible?
ps: Sorry I am new here and apologize if I ask a stupid question.

Hi, derf
Thank u so much!
I have successfully implemented the hover mode using some others' code. Yes, hover mode can be implemented by the PC client using the crazy radio. However, I wonder whether the copter can autonomously hold its altitude without any external radio. With the help of on-chip barometer and embedded processor, is it even possible to construct a closed loop altitude control of itself?

The PC client is only used to set the set point and visualise the sensor data/computed values. All calculations are done on the flie.

Thanks for your kindly reminder, I got it.
