一般的な説明

ファンコントローラのコンポーネントは、PSoCデザイナーが早く簡単にファンコントローラソリューションを作ることを可能にします。The component is a system-level solution that encapsulates all necessary hardware blocks including PWMs, or TCPWMs for PSoC 4, tachometer input capture timer, control registers, status registers and a DMA controller (ISR for PSoC 4) reducing development time and effort.

The component is customizable through a graphical user interface enabling designers to enter fan electromechanical parameters such as duty cycle-to-RPM mapping and physical fan bank organization. Performance parameters including PWM frequency and resolution as well as open or closed loop control methodology can be configured through the same user interface. Once the system parameters are entered, the component delivers the most optimal implementation saving resources within PSoC to enable integration of other thermal management and system management functionality. Easy-to-use APIs are provided to enable firmware developers to get up and running quickly.
