Chapter 12 Serial Bus Trigger and Decode
(Optional)
This chapter contains the detailed information of serial bus decoding. You are recommended to read this chapter
carefully to understand the setting and operation of tBook mini series bus trigger and decode.
This chapter mainly include the below contents:
⚫
UART (RS232/RS422/RS485) bus trigger and decode
⚫
LIN bus trigger and decode
⚫
CAN bus trigger and decode
⚫
SPI bus trigger and decode
⚫
I2C bus trigger and decode
⚫
ARINC429 bus trigger and decode
⚫
1553B bus trigger and decode
Press
in the lower right corner to switch to decode channels
, tap
or
to
enable decoding, open bus configuration menu, select bus type, there are seven bus types: UART
(RS232/RS422/RS485), LIN, CAN, SPI, I2C, ARINC429, 1553B, where channels
and
can be
used for decoding simultaneously. Open the trigger setting menu, choose an appropriate trigger type, the
corresponding bus trigger type and trigger mode can be set when the bus trigger is selected, and the serial bus is
displayed in graphic form.
In the serial bus decode mode, if it is screen rolling in other modes, the time base is automatically adjusted to
1ms when switching to serial decode (the maximum time base supported by the serial decode mode is 100ms);
in Zoom mode, the enlarged signal can be decoded and displayed. The normal display window supports a
maximum time base of 100ms. When decoding is enabled, clicking “AUTO” will set the trigger type to be the
same as the decode channel bus type. The bus type selection menu is shown in Figure 12-1:
