Triggering device for CANbus
Piroch, Vojtěch ; Arm, Jakub (referee) ; Burian, František (advisor)
This bachelor thesis deals with the design of a triggering device for the CAN bus that allows connection to the trigger input of an oscilloscope and display of the signal waveforms of the CAN bus frames. The first part of the thesis deals with the theoretical description of the CAN bus itself, its principle of operation, description of frames, etc. The second part of the thesis deals with the selection of the core components needed for the circuit, the design of the final schematic, the definition and calculation of the individual components in the circuit and the method of control. The third part is practical, it is dealing with testing the prototype device, designing the circuit board and packaging for the device. The following section describes the software part of the device, specifically how to control the device, a description of the program and libraries used in programming the microcontroller. The last section describes the final testing and measurement of parameters such as jitter and trigger pulse delay.
