STM32单片机实现one－wire信号读取，读取ds18b20的数据。-STM32 MCU one-wire signal is read, read ds18b20 data.

采集器程序，通过读取固定长度的条码，从而采集数据保存到采集器中，然后上传到电脑里。-Collector program by reading a fixed length of the bar code to collect data to the collector, and then uploaded to the computer.

2440 ADC和触摸屏接口有 等待中断模式 的特性。所以需要编写一个中断函数，来完成ADC数据的读取。 以下代码均在友善提供的ucos移植版上测试通过～-2440 ADC and touch screen interface features have to wait for interrupt mode. Therefore need to write an interrupt function, to complete the ADC data read.
