For example, when our mobile phone is plugged into the computer as a modem, many serial ports will be virtualized. These include general serial ports and modem serial ports. How is this implemented? W...
Why do I turn off the UART clock during initialization when using UART?
UART1_Init((u32)9600, UART1_WORDLENGTH_8D, UART1_STOPBITS_1, UART1_PARITY_NO, UART1_SYNCMODE_CLOCK_DISABLE, UART1_MODE_RX_ENABLE...
I have already used T0 and T1. Now I need to use the serial port, so I simulated one. I need to use a timer. I also have T2, and I want to set it as a timer. Because the simulated serial port requires...
What are the functions of the four registers FIOn_FLAG_D, FIOn_FLAG_S, FIOn_FLAG_C, and FIOn_FLAG_T? How are they used? I have read the hardware manual for a long time but still don't understand. Can ...
1. RS232 is connected to the computer. Does the PLC need to be connected to the power supply for programming? 2. Can RS485 make the rs232-485 converter (same as the RS485 communication card) do contro...
