I/O Port #H

The module has 16 I/O port lines, which can be expanded to up to 125. If the port input pins are changed, macros can be started, see #MHP, and #MHB.

Port-Access (8 I/Os)

Define port (input/Ausgang)

#HPC

Port, I/O, I/O [Port+1], ...

The command defines the direction (I/O) of the individual port pins bit by bit for an entire Port [0 ... 15]:

Read port inputs

#HPR

Port (0), Number(2)

The command puts the state of one or more (Number) of ports (starting with Port) in the send buffer. The feedback is structured as follows:

ESC

Send port information

#HPI

Indicates which of the 16 possible port modules are connected (= 1) and places this information in the send buffer. The feedback is structured as follows:

ESC

H

P

#HPI

The port expander with address 0 is internally available, that means without external hardware the return value is 1.

Pin-Access
