Serial Bus
The serial bus trigger and decode software includes support for 3
common serial interfaces, SPI (4 channel models only), UART and
I
2
C. Each interface is fully configurable to accommodate a wide
range of protocol variation.
Each input can be displayed as binary or hexadecimal. An event
table can also be created to aid in debugging.
Note that the Serial bus trigger and decode software is an optional
extra. An activation key is required to activate the software, for
details please see page 191. Please see the Serial Bus Decode
manual for more details on using the serial bus software.
