Game Development Reference
In-Depth Information
As newer versions are released, there will be more commands available in here.
To check the current GPU temperature, use the following command:
vcgencmd measure_temp
We can use the following command to check how RAM is split for the CPU and GPU:
vcgencmd get_mem arm/gpu
To check the firmware version, use the following command:
vcgencmd version
The output of all these commands is simple text that can be parsed and displayed on
a website or stored in a database.
Summary
The Raspberry Pi has very capable GPU and ARM processors with features that
might not have been disclosed or discovered yet. Open development is slowed
down by the fact that Broadcom is keeping everything closed source, and even if
somebody gets a peak at some source code, they enforce strict non-disclosure terms
and conditions. It is still in the early stages of development, but the hype created
around the Raspberry Pi has brought you, me, and thousands of people to this
hack space.
This chapter's intention was to teach you about how hardware relies on good
software, but most importantly, to it also shows you how to leverage hardware
using ready-made software packages.
In the next chapter, we will look at how to configure a web server and a database.
