本代码实现4×4键盘操作 对键盘进行扫描取得键入值

很少见的源码公开的msc51和z80的c编译器。-rarely seen in the open-source and Z80 msc51 c compiler.

飞利浦的80C552串口通信代码，可通过PC机完成对单片机的控制，并向上位机返回数据。-80C552 bunches of communication code of Philip, can finish the control on one-chip computer through the PC , and return to the data in the upward location machine.

l298调 速 程 序 常规的接法是这样的，EnableA接PWM信号，Input1输入正反控制信号， Input2是Input1经过反相以后的信号。L298的电平是与TTL电路相兼容的，一般是超过2.5V就为高电平。假如Input1为高电平时电机正转，那么低电平时就是反转，PWM信号控制电机的转速。 _________________ -l298 procedures conventional speed connection that is the case, EnableA then PWM signal, Input1 input positive and negative control signals, Input2 is Input1 through after RP signal. L298 level is compatible with TTL circuits, and is generally more than 2.5V for the high. If Input1 is high when the motor is transferred, then that is when low-level inversion, PWM signal to control motor speed. _________________
