SPI Serial Bus Interface
The serial peripheral interface (SPI) is a full duplex 4 wire
synchronous serial interface. The 4 signals lines: Serial clock line
(SCLK), slave select (SS), Master output/slave input (MOSI, or
SIMO) and the Master input/slave output (MISO, or SOMI). The
word size is configurable from 4 to 32 bits. The SPI triggers on the
data pattern at the start of each framing period. Note: The SPI bus
is only available for 4 channel models.
Panel operation
1. Connect each of the bus signals (SCLK, SS,
MOSI, MISO) to one of the channel inputs.
Connect the ground potential of the bus to one
of the probes’ ground clip.
