da14580低功耗实验，唤醒信号设计，详细的实验代码和过程解析

Dialog’s Bluetooth Smart wireless keyboard reference design is built on its world-leading DA14580 Bluetooth Smart chip and takes advantages of the chip’s capabilities to push the boundaries of wireless keyboard battery lifetime longevity and Bill of Materials (BoM). The reference design includes all necessary hardware, software and documentation to design a keyboard guaranteeing fastest time-to-market with minimal development investment and effort.
The software is provided in source code and offers all of the flexibility to customize the keyboard and wireless connection parameters according to your application’s needs. Features 109-key keyboard with numeric keypad and function keys 2 LEDs for connection status and low battery indication Lowest BoM Powers from a single AAA alkaline or NiMH battery Minimal external component count with only 16 passive components required for the complete keyboard system Double the battery lifetime of current available solutions with less than 5 mA peak current consumption in active mode and less than 600 nA in stand-by Programmable connection interval and slave latency Multi-key press detection 6-key simultaneous press reporting De-ghosting (for multiple key combinations) Wake-up from deep sleep with any key press Supports connection to multiple hosts Programmable deep sleep entry time All key parameters are SW customizable Interoperability with all major operating systems: Win 8.1, iOS7 and Android 4.3 and beyond WHQL certifiable

Dialog’s Bluetooth Smart wireless mouse reference design is built on its world-leading DA14580 Bluetooth Smart device. The design takes advantage of the DA14580’s capabilities to give excellent battery lifetime and a low Bill of Materials (BoM). The reference design includes all necessary hardware, software and documentation to design a mouse, guaranteeing fastest time-to-market with minimal development investment and effort. The software is provided in source code and offers wide flexibility to customize the mouse and wireless connection parameters according the application’s needs. Features Laser optical sensor with resolution up to 3200cpi and multi-stage power management for optimal performance with minimal power consumption Full range of mouse buttons (Left, Right, Middle) and precise mouse scroll wheel navigation Fast response to key events Simultaneous key-press Highly integrated design, allows for very low external components count (BoM. Powers from a single AA alkaline or NiMH battery Double the battery lifetime of current available solutions EEPROM functionality for storing link keys Supports connection to multiple hosts All key parameters are SW customizable Programmable time to enter deep-sleep when in inactivity Wake-up from deep-sleep on any key event or mouse movement Interoperability with all major operating systems: Win 8.1, iOS7 and Android 4.3 and beyond WHQL certifiable
