By clicking the RUN button the recording is started. The status display informs you whether the process
is still running (WAITING) or has already been completed (DONE). After finishing the acquisition, the
results are displayed in a graph. Additional trigger options LOW and HIGH are used for the so called
Patterned triggering. For example: If you set the trigger source to be DIN0 – Rising edge (to have one
channel defined as a trigger source with a rising or falling edge is a mandatory condition for the
acquisition to start), DIN1 to HIGH and DIN2 to LOW this will cause such a behavior that the application
logic will wait for the state where DIN0 goes from 0 to 1, DIN1 is 1 and DIN2 is 0 to start the acquisition.
3.3.1.3. DECODE BUS DATA
In the DIGITAL → BUS menu the decoding of the desired lines can be selected. Up to 4 buses can be
defined. The available decoding protocols are I2C, UART, and SPI. By selecting the desired protocol, the
setting menu for the selected protocol is opened.
Two options are possible for the display of the decoded data: firstly, the data is placed as a separate
layer in the graph directly on the signal. Secondly, using the DIGITAL → DATA menu where the decoded
data are represented in a table format. You can select ASCII, DEC, BIN and HEX data formatting. With the
EXPORT button the decoded data can be packed into a CSV file. This then ends up directly in the
download folder and can be used for further analysis.
3.3.1.4. CURSORS
As with the Oscilloscope the Logic Analyzer App also provides CURSORS for quick measurements.
Because there are no variable amplitude readings but only discrete signal levels, the cursors are
available exclusively for the X axis. When enabled, the cursors will show the relative time respectively to
zero point (trigger event) and the difference between the two.
