K型热电偶信号转换放大器MAX6675的驱动设置程序。该程序能控制MAX6675对K型热电偶的微弱信号进行放大、AD转换。-K-type thermocouple signal converter amplifier MAX6675 driver setup program. The program can control the MAX6675 on the K-type thermocouple of weak signal amplification, AD conversion.

基于MSP430的十二位AD转换芯片ADS7886驱动代码，转换精度高，适合对微弱信号采集。-MSP430-based twelve-bit AD conversion chip ADS7886 driver code, the conversion of high precision, suitable for weak signal acquisition.

密码锁控制器，用户可通过键盘输入密码。弱密码正确，则单片机输出控制信号驱动电机转动，带动锁舌缩进动作。-Password lock controller, the user can enter the password via the keyboard. Weak password is correct, then the microcontroller output control signal to drive the motor rotation, drive bolt indent ac

用STM32F407写的用于进行微弱信号检测时的程序，使用了锁相放大器。-Written in STM32F407 for weak signal detection program, using the phase-locked amplifier.
