You can analyze the decoded bus with symbolic labels based on DBC file information. Just import the label file and you can start showing the bus frames as a symbol. In addition, you can select your trigger based on bus label. Triggering on symbolic data is also possible....
结构如图所示,CAN-BUS总线系统上的控 制器中发送信息的线路通过一个开路集电极 和总线相连,因此总线导线上就会出现两种 状态:0和1两种逻辑。 “0”表示控制器开关闭合,晶体导通, 电阻值低,处于通信状态;“1”表示控制器 单个CAN收发器与总线信息转换 开关断开,晶体管截止,电阻值高,总线未 通信。 四.CAN总线通讯...
each module on the high speed network was disconnected in turn until the network signal returned to the waveform expected. When the Anti-Lock Brake module was disconnected the oscilloscope displayed the following waveform:
When the test is exited, the scope will restore most oscilloscope settings to the state they were in prior to beginning the test. Figure 4. CAN eye-diagram mask test on a 500 kbps differential bus viewed in a dominant-bit-low format. Interpreting the Eye The CAN 2.0 eye-diagram test ...
Debugging CAN, LIN and FlexRay Automotive Buses with an Oscilloscope Video CAN Bus Decode and Trigger on the 5 Series MSO Frequently Asked Questions What is a CAN bus decoder? What is the benefits of using a CAN bus decoder? How does a CAN bus decoder work?
To check out the timing, I wired up a pi3hat into the quad A1 and used the oscilloscope to probe one of the SPI clocks and CAN bus 1 and 3. Then, I could use pi3hat_tool incantations to experiment with different bus utilization strategies and get to one with the best performance. Th...

When I tried my code today, I did not receive any errors (the error flag is not triggered). However, when I probed Tx (PB1) to the oscilloscope directly with reference to GND (without connecting to the transc...
The utility model provides a controller area network (CAN) bus testing device. The device comprises: a power supply module supplying a CAN master control device, a CAN device under test, a testing host and an oscilloscope with power; the CAN master control device, which, under the control ...
Could you share how you are measuring the output? Are you using an oscilloscope/logic analyzer or a CAN Analyzer? Keep in mind that for user/normal mode a second node (another MCU or CAN Analyzer) must be connected to the bus line. You can useExample S32K344 FlexCAN_Ip TX/RX/Enhance...
