This is my first time to use CAN bus. Recently, I need to send and receive data through CAN bus. When I use microcontroller to send ID=0x401, I check the waveform and find that the actual data sent is
Knowledge point 1: pointer
1. Pointer: The first number of the variable's storage space in memory is called the address of the variable, also called a pointer.
Pointer variable: It is used to store a
There are two main issues here:
1) How are the 2Ω of R150 and the 300Ω of R151 calculated? Or is it an empirical value? Is the 300Ω just used for current limiting of the voltage regulator BZX84-B13?

Traditional fieldbus networks generally use wired media as transmission media. Wired transmission media make the location of communication equipment relatively fixed. Some special industrial field env
