Trigger condition setup with Address: 1F and First byte data: 00
|The I²C trigger types are: Start Trigger (bus start condition), Non-Ack Trigger (when acknowledgement bit is not received), and Address (7 bit address + 1 read / write bit) & Data (1 byte data) Trigger. The I²C triggers described above can be also combined with other signals on channels 3 or 4. For example, a Start trigger could be combined with a control or feedback signal.|
Analysis results of 6.4 seconds of I²C data
|I²C bus data acquired to super large memory (32 M words /channel maximum) are analyzed in a time series. Analyzed results are decoded and displayed one byte at a time. The function can analyze very long data sequences up to 40,000 bytes. When a cursor is moved over the onscreen data, the corresponding waveform can be automatically enlarged in the zoom area. |
Easy comparison with communication data and the displayed waveforms enables effective debugging . Alternately analyze 2 I²C buses using all 4 channels: SCL1-Channel 1, SDA-Channel 2, SCL2-Channel 3; SDA2-Channel 4.
Example: Searched Address 1F(H) and Data 20(H)
|Quickly search for specified addresses and data in the analyzed results. When the specified data are found, the cursors automatically move to the corresponding location, and the waveform is enlarged in the zoom area. The data search functions are particularly useful for extracting desired addresses or data from long sequences of data such as 1000 byte data. Indefinite data can be searched by setting Upper and Lower threshold levels.|
SPI analysis results display
|The I²C bus analysis option also offers SPI bus analysis . SPI bus is a synchronous 8-bit serial bus widely used for Inter-IC communication. |
Analysis Results Display
You can simultaneously display waveforms and Data1, Data2, and CS information. Data highlighted using a cursor is enlarged in the Zoom window. Upper and Lower threshold levels can be set to search for indefinite data.
Data Search Function
Automatically detects a specified data pattern from the target data.
