Making devices computer friendly
Data transfer between electronic devices and a PC (computer) has increased in recent years. Most RS232 serial compliant electronic devices that require connection to a PC are equipped with TTL/CMOS UART interface. Serial data transfer on a PC are increasingly being accomplished using USB technology, in preference to the traditional RS232 serial port which is almost phasing out. This piece shows how to accomplish serial data transfer between UART devices and a PC via USB port.
