DP Alternate Mode的沟通 而在DP母座一侧,HUSB252会监测HPD引脚的状态,判断外接显示器的连接状态,并将实时的HPD(Hot Plug Detection/热拔插检测)信号状态以PD消息的形式告知笔记本电脑。笔记本电脑的DP Source在获取到显示器接入的情况下, 会继续在SBU/AUX通道上完成DP的协议沟通后输出视频数据流, 完成投屏动作。
Upon Hot Plug detection, the Source device configures the link through link training. The correct number of lanes is enabled at the correct link rate with the correct drive current and equalization level through the handshake between DisplayPort transmitter and receiver via AUX CH.(懂了吗?我觉得有...
The DisplayPort Alternate Mode allows video data to be delivered through the SuperSpeed USB lines on the Type-C connector, while Auxiliary lanes (AUX) and hot plug detection (HPD) signals are sent through other Type-C lines. The high-performance ARM®Cortex®-M0 32-bit STM32F072 ...
