【应用】基于沁恒微控制器CH582的BLE/2.4G/USB三模机械键盘方案,集成度高,功耗更低
在键盘鼠标等外设中,“三模”顾名思义就是指三种不同的连接模式。其中USB有线即插即用,同时还能够提供更好的实时性;2.4G无线则既有无线的便利,又可以提供媲美有线的低延迟;而蓝牙则可以与PC、平板电脑、手机等多种设备快速连接切换,不占用USB口,办公使用更方便。机械键盘具有打击感强的优点,而三模机械键盘融合了三模键盘和机械键盘的优点,既能带来优秀的游戏体验,又能兼顾办公使用的便利。
传统的机械键盘方案,方案集成度不高,分立器件和模块组合,主要由USB MCU,BLE数传模块,RGB灯光驱动芯片组成,外围复杂,方案成本较高。CH582机械键盘方案和传统机械键盘方案对比,单芯片集成BLE、RF和USB模块,集成度高,功耗更低,集成多路PWM驱动接口,用于键盘背光控制,同时集成IIC/SPI接口,便于RGB拓展控制。
基于CH582的单芯片机械键盘多模方案框图:
CH582三模机械键盘方案主要功能:
沁恒CH582是集成BLE无线通讯的32位RISC-V微控制器,片上集成2Mbps低功耗蓝牙BLE5.3通讯模块、2个全速USB2.0主机和设备控制器及收发器、2个SPI、4个串口、ADC、触摸按键检测模块、RTC等丰富的外设资源,工业级温度范围-40℃~+85℃,可提供QFN48、QFN28多种封装。
USB模式:
芯片自带2个全速USB2.0主机和设备控制器及收发器支持普通8字节键盘数据传输,同时也支持16字节位键传输,做到真正全键无冲,全速上传;USB设备复合HID兼容设备,配合专用的PC端软件可以用来进行固件更新、键值宏定义、炫彩灯效模式设置等功能。
RF2.4G模式:
热键(可自定义)切换至RF 2.4G模式,配合USB Dongle,实现媲美有线的按键响应速度;RF2.4G模式已经完成基于MAC地址(每个芯片有全球唯一的MAC)的配对,自适应跳频算法,避开空中无线干扰和拥挤信道。
BLE模式:
芯片集成2Mbps低功耗蓝牙BLE5.3 通讯模块,蓝牙模式可以直接连接PC、手机、平板等主机,且支持4台主机的配对信息存储,一键切换主机。
灯效控制:
单芯片CH582键盘方案,支持单色灯效控制,片上集成(4+8)12路PWM控制信号;如果需要炫酷的RGB灯效,可以通过SPI/I2C 扩展控制CH555芯片实现RGB灯效控制。CH555是E8051单片机,内置的128组RGB三色LED控制器和USB Device功能,可用于RGB灯效控制或者机械键盘设计。
其他功能:CH582自带12bit ADC,支持ADC电量采集;芯片提供4种低功耗模式,最低的睡眠电流低至0.2uA。
