This manual discusses modules and peripherals of the MSP430x1xx family of devices. Each discussion presents the module or peripheral in a general sense. Not all features and functions of all modules or peripherals are present on all devices. In addition, modules or peripherals may differ in their exact implementation between device families, or may not be fully implemented on an individual device or device family. Pin functions, internal signal connections and operational paramenters differ device-to-device. The user should consult the device-specific datasheet for these details.

This project of digital thermostat is made in asm.

变压器绕组变形在线监控中考虑套管的影响，有FEM模型的建立和仿真实例(Detecting the early signs of mechanical failures of power transformer winding is necessary and is possible with online monitoring techniques. Online impulse frequency response analysis (IFRA) is a promising diagnostic method when a transformer is in service)
