Full Angel requires use of at least one device driver for its own communications requirements. If you are using Angel on a board with more than one serial port, such as the PID board, you can either:
use Angel on one serial port and your own device on the other
use minimal Angel, which requires no serial port, and use either or both of the serial ports for your application.
The PID Angel port provides examples of raw serial drivers. Refer to the Angel source code for details of how these are implemented. If you want to use Angel with your own hardware you must write your own device drivers. Refer to Writing the device drivers for more information.
Figure 13.3 gives an overview of the Angel serial device architecture.
