PERIPHERALS - INTERFACE
The module has various interfaces:
- 4 analogue inputs (12-bit precision)
- 1 PWM output (16-bit precision)
- Video input (PAL/SECAM Analogue)
- Audio output (8-ohm loudspeaker, max. 1 W)
- 16 digital I/O, extendable to up to 128 (max. 20 mA)
- 3 serial interfaces RS232, SPI, I²C
Parameters that are written in GREY in the command tables are considered optional details, and partially have default values. The default values are
given in brackets behind the corresponding parameters. Parameters written in BLACK on the other hand, must be assigned values. Commands that
may contribute towards changing parameters can only be used if the corresponding parameters have already previously been defined. Some com-
mands allow for entering several object IDs. Should these objects be in numerical sequence, the range may be specified with the “-” sign, e.g. 1-5, instead
of 1,2,3,4,5.
ANALOGUE
Designation Command code Description
Calibrate analogue converter #HAC Executes the calibration of the analogue
converter.
Analogue input - hysteresis #HAH Channel, Hysteresis (1) Defines the hysteresis of the analogue
input Channel(0-3). Not all changes in
value are displayed by specifying hyste-
resis Hysteresis, but only changes in value
as from the size specified. If the hysteresis
is not specified, all changes in value are
displayed, i.e. Hysteresis = 1.
Read analogue input #HAL Channel, Limit, Limit2 Defines an upper and lower limit Limit,
Limit 2 for the analogue input Channel(0-
3).
Read analogue input #HAR Channel(0), Number(4) Scans the analogue input Channel(0-3).
The number Number(1-4) specifies the
number of inputs to be read. Example:
Channel = 1, Number = 2 leads to the ana-
logue inputs 1 and 2 being scanned, and dis-
played via the serial interface. A more
precise description of the system response
can be found in the chapter Responsens.
