STM32与台达变频器通过modbus通讯，6通道ADC采样并做解耦运算(STM32 and delta frequency converter through Modbus communication, 6 channel ADC sampling and decoupling)

利用STM32单片机连接PM2.5传感器，检测PM2.5和PM10，采用modbus方式受上位机控制。(PM2.5 sensor is connected with STM32 single chip computer to detect PM2.5 and PM10. The upper computer controls PM2.5 and PM10 by Modbus mode.)
