Description: The design is based on VHDL language to achieve bit serial RS232 communication bus according to the determinant of matrix keyboard interface circuit with a reset, and serial data reception and transmission capabilities, according to light-emitting diode display led0-led2 status can be judged chip work to achieve all the circuit functions of the program are produced in the United States has ALTERA Field Programmable functions EPM7128SLC84-15 on-chip debug passed. The circuit design of daily life, practical, post-produced chips can be used as a general PC, the keyboard and the host interface.
- [UART] - Using FPGA to achieve the RS232 asynchro
