Serial Port printing information can be added to any code to facilitate debugging. You do not have to have a printf statement. This can be implemented in a simple way. First, you need to complete the serial port register initialization, including the input and output enabling, data bit and stop bit, baud rate, interrup

Properties set in the control serial port Cache size. It is recommended that the data received per second be more than 10 times Important: this setting is important when the data volume received in the cache triggers a notification event. It is best to set no more than 10 trigger events per second. That is, when the amount of data received per second is 1000, set 100 ~ 400 trigger. This problem is time-con

The RS232 interface is a standard for serial communication jointly developed by the American Association of Electronic Industry (EIA) and bell system, modulation regulator manufacturers and computer terminal manufacturers in 1970. Its full name is "Technical Standard for Serial Binary data exchange interfaces between data terminal devices (DTE) and data communication devices (DCE)", which requires a 25-pin

Network address port Conversion NAPT is a very familiar way of transformation. NAPT is commonly used in access devices, which can hide small and medium-sized networks behind a legitimate IP address.Unlike dynamic address NAT, NAPT maps An internal connection to a separate IP address in the external network, adding a TCP port number selected by the NAT device to the address.This time, let's get to know napt.
