1 can bus 2 data cable is how to represent data information 1 and 0?The can bus uses the differential data representation method, usually 2 data line is 2.5V, indicates the recessive (1). When using data 0 (dominant) need to send 1 with the data line up to 3.5V another down to 1.5V. A is shownAll nodes are connected to these two data lines, and when all the nodes are sending data as recessive, the bus data is represented as recessive, and if one of the nodes sends the data dominant the bus data
Boost converter (boost)The boost converter (boost) is the only option when the input voltage needs to be converted to a higher output voltage.The boost converter uses the internal MOSFET to charge the voltage to achieve the purpose of the boost output and, when the MOSFET is off, discharges the inductor through a load rectification.The conversion process between the inductor charge and the discharge will reverse the direction of the voltage passing through the inductor, thus gradually lifting th
