stm32f103最小系统以及数据采集设计，包括最小系统AD图，底层源码(STM32F103 Minimum System and Data Acquisition Design, including Minimum System AD Diagram, Bottom Source Code)

单片机通过PWM输出供电，驱动3个串联电阻，其中50K是一个电位器，人为不断的旋动电位器，来模拟负载无规律的变化。 目标要求：100uF电容两端的电压不受负载的影响，即ADC读数要求稳定在100左右。 大概的输出电压mV = 5000mV * ADC读数 / 255 调整 P、I、D 这三个系数，还有调整间隔检测时间，即可调整负载电压的稳定度和皱纹度。 (单片机通过PWM输出供电，驱动3个串联电阻，其中50K是一个电位器，人为不断的旋动电位器，来模拟负载无规律的变化。 目标要求：100uF电容两端的电压不受负载的影响，即ADC读数要求稳定在100左右。 大概的输出电压mV = 5000mV* ADC读数/255 调整 P、I、D 这三个系数，还有调整间隔检测时间，即可调整负载电压的稳定度和皱纹度。 )
