4.7.6 SYN – Synchronize Buﬀered IO State

Function Enable command buﬀering

Command byte 0x88

Argument list –

Use this command before you start issuing write commands you want to buﬀer. To end

the buﬀer process, issue a TRG command.

4.7.7 TRG – Trigger IO State Buﬀer Execution

Function Execute all buﬀered IO states (i.e. copy buﬀer to current and write

out pin states)

Command byte 0x89

Argument list –

Use this command to write out the buﬀered IO states, i.e. change all IO states in the

same instant.

The buﬀering is thereby turned oﬀ and all future write commands will be executed instan-

taneously, until you execute another SYN command.

4.7.8 LNK – Set-up IO matrix

Function Link output pin range to input/virtual pin z

Command byte 0x84

Argument list First pin to set, last pin to set, target pin address

Example arguments 0x01 0x00 | 0x00 0x00 | 0x02 0x00 (Link pin P1 to pin P2 )

If the last pin number equals 0, only one pin state will be changed. Pins that are not of

output type are skipped. If the target pin address is a physical pin, and said physical pin is

of output type 0x03, it will be set to tristate input type.

If the LNK command is used on a pin where PWM output is currently active, LNK takes

priority until cleared by the CLR command.

4.7.9 PWM – Conﬁgure Pulse Width Modulation

Function Set PWM ratio for pin range

Command byte 0x85

Argument list First pin to change, last pin to change, PWM ratio (PWM_R)

Example arguments 0x01 0x00 | 0x02 0x00 | 0x3f (This would set the pins P1 and P2

to a 50% PWM ratio, i.e. if LEDs were to be connected, they’d

be on half brightness)

The PWM on/oﬀ ratio will be PWM_R:127.
