:BUS<n>:SPI:ENDian
Syntax
:BUS<n>:SPI:ENDian <endian>
:BUS<n>:SPI:ENDian?
Description
Sets or queries the endian of data transmission of SPI decoding.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<endian>
Discrete
{MSB|LSB}
MSB
Remarks
 MSB: indicates Most Significant Bit transmission sequence, i.g. the highest bit of
the data is transmitted first.
 LSB: indicates Least Significant Bit transmission sequence, i.g. the lowest bit of
the data is transmitted first.
Return
Format
The query returns MSB or LSB.
Example
:BUS1:SPI:ENDian LSB /*Sets the endian of data transmission of SPI decoding
to LSB.*/
:BUS1:SPI:ENDian? /*The query returns LSB.*/
:BUS<n>:SPI:MODE
Syntax
:BUS<n>:SPI:MODE <mode>
:BUS<n>:SPI:MODE?
Description
Sets or queries the decode mode of SPI decoding.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<mode>
Discrete
{CS|TIMeout}
TIMeout
Remarks
 CS: indicates chip select. CS: contains a chip select line (CS). You can perform
frame synchronization according to CS.
 TIMeout: indicates timed out. You can perform frame synchronization according to
the timeout. At this time, you can send the :BUS<n>:SPI:TIMeout:TIME
command to set the timeout value.
Return
Format
The query returns CS or TIM.
Example
:BUS1:SPI:MODE CS /*Sets the decode mode of SPI decoding to CS.*/
:BUS1:SPI:MODE? /*The query returns CS.*/
