此资料为AT45DB161D 的驱动程序，希望对使用此芯片的朋友有所帮助(This is a AT45DB161D driver, want to use this time to develop the chip would be helpful friend)

根据设计任务书的要求，本次设计为110kV 变电站电气一次部分初步设计，并绘 制电气主接线图及其他图纸。该变电站设有两台主变压器，站内主接线分为110kV、 35kV 和10kV 三个电压等级。各个电压等级分别采用单母线分段接线、单母线分段带 旁母接线和单母线分段接线(From the guide of engineering design assignment, we have to design primary power-system of 110kV substation and draw main electrical one-line diagram and others. There are two main transformer in the substation in which main electrical connection can be divided into three voltage grades: 110kV, 35kV with 10kV.It deposits sectionalized single bus bar scheme, sectionalized single and transfer bus bar and sectionalized single bus bar scheme per grade.)

说明：  stm32f103芯片驱动SX1278，小型RTOS，处理SX1278信号，空中唤醒(STM32F103 chip drives sx1278, small RTOS, processes sx1278 signal, wakes up in the air)

实时水流加热，可控水温的温度，经过水流量来精确控温无过冲热，温控精度高(heat flow watter!)
