Serial interfaces
The module provides 4 serial interfaces, including RS232, SPI, I²C and USB. In addition to the USB interface, the other interfaces can change your behaviour:
They can either be used to connect to an external host, i.e. to a higher-level controller, or used as a master interface.
By default, all interfaces are parameterized as slaves and accept the commands.
Parameterized as a master interface, it enables the control of external sensors and actuators. The display module behaves here as a master.
As already described, the interfaces behave as slave interfaces by default and accept commands. However, as soon as a master interface command (#H ...)is executed, the interface gets master functions.
