1. If the MCU has a serial port peripheral, adding a level conversion chip, such as MAX232, SP3485, will become the RS232 and RS485 interface.
2. RS485 uses differential signal negative logic, +2~+6V

How to get out of the area of "the calculation formula of capacitors with DC isolation, AC passing and capacitive reactance", I found that I am still at this stage. I don't know how to analyze the cap
SRIO error detection is mainly divided into two parts, physical layer error detection, logical layer / transport layer error detection, each error detection has a specific register to control. Physica
