| Abstract: | In order to upgrade the interface of electronic device from RS232 to USB,a USB-RS232 converter based on CY7C68013 was designed.The frame of system was briefly described.The firmware and driver programme were introduced in details.Data buffering technology for speed matching between RS232 and USB was used in the design of firmware.Using one compute simulating RS232 device to communicate with the other with USB2.0,the experimental tests proved that the device was feasible and stable.Furthermore,the design supplied a reference for development of other USB devices. |
