tlc5615的驱动程序。程序也用过，比较好， 非常高兴能和大家分享。-tlc5615 drivers. Procedures used were relatively good, and very pleased to share with you all.

DTMF双向收／发集成电路MT8880专门为双音频信号的收、发而设计，它既能产生发送双音频信号，又能对双音频信号进行接收译码，还能判断各种信号音(拨号音、回铃音、忙音)。以上就是它的应用电路和程序-Two-way DTMF collection/fat MT8880 IC specifically for the dual audio signals received, the design, it could have sent dual audio signal, while the dual audio signal decoding receiver, but also to judge the sound signal (dial tone , ring back tone, busy tone). Above is its application circuit and procedures

步进电机程序，用l297 l298作为驱动电路的，程序比较简单，但是能对mcs-51中断有个详细认识-Stepper motor program l297 l298 as a driving circuit, the procedure is relatively simple, but can be interrupted for mcs-51 has a detailed understanding of

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. _________________
