MSP430开发，功能强大，非常适合于MSP430单片机开发。(MSP430 development, powerful, very suitable for single-chip MSP430 development.)

说明：  主控cpu采用stm32f407vet6,采用口线模拟的spi总线来采集ads1118的俩路输入模拟信号。信号输入范围为0--2.048V。对应0--65535.(The main control cpu adopts stm32f407vet6, and adopts the spi bus of port line simulation to collect the two input analog signals of ads1118. The signal input range is 0--2.048V. Corresponds to 0--65535.)

基于stm8l15x系列单片机移植的bmp180气压海拔传感去驱动程序模拟IIC，实际用stm8l152K4T6单片机，串口打印数据，亲测可用。( Bmp180 pressure altitude sensor stm8l15x MCU-based portable driver to simulate IIC, the actual use of stm8l152K4T6 microcontroller, serial print data, pro-test available.)
