Description: This procedure using the MSP430F149 the PC interface driver PS2 keyboard, used for SN74LVC4245 level conversion PS2 port using a standard six-core socket, you can receive from the standard keyboard and mouse data. As the keyboard, mouse are 5V power supply system, while the MSP430F149 can only work in 3.3V, so it is necessary to carry out between the two-level conversion. According to the working principle of the keyboard, MCU as long as the receiver from the keyboard to send the clock signal and data signals, data signals and then decode it. To this end, we made use of level-shifting circuit of two data lines, so that the keyboard clock line CLK of the A8 connection SN74LVC4245 port, keyboard data line DATA port to connect SN74LVC4245 the A7
