msp430的程控放大电路 protues 7.8 的仿真图带程序 绝对可以运行！步进为AV=5-The simulation diagram with program the msp430 program-controlled amplifier protues 7.8 can definitely run! Step AV = 5

在一组IO口中（8个IO）用6个实现8个按键检测，另两个不受干扰，有PROTUES仿真电路-6 in a group of 8 of the IO mouth (IO) achieve the eight key detection, the other two will be uninterrupted, PROTUES simulation circuit
