CDC_Control_FS()来自主机请求的回调函数 CDC_Receive_FS()接收数据回调函数; CDC_Transmit_FS()用来发送数据; CDC_TransmitCplt_FS()发送完成回调函数; 发送 uint8_t CDC_Transmit_FS ( uint8_t* Buf, uint16_t Len ); static int8_t CDC_TransmitCplt_HS
说到智能化配置,理想家的车确实有一套。不管是带空气悬挂的理想L9,还是新出的2025款理想L8、L7,都挺值得去体验体验的。
一、USB简介 stm32F746系列芯片有USB_OTG_FS和USB_OTG_HS两种接口,FS为全速,速度12M Bit/s,HS为高速,最高速度为480M Bit/s,此时需要外接USB HS PHY,例如USB3300。HS接口也可以作为FS接口使用。由于FS和HS接口使用是相同的USB设备库,只是初始化时配置的引脚不一样,本章以FS接口为例讲解USB设备库的使用。...
Infection control procedures including administrative rules and engineering controls, environmental hygiene, correct work practices, and appropriate use of personal protective equipment (PPE) are all necessary to prevent infections fro...
CDC::GetPath Retrieves the coordinates defining the endpoints of lines and the control points of curves found in the path that is selected into the device context. CDC::GetPixel Retrieves the RGB color value of the pixel at the specified point. CDC::GetPolyFillMode Retrieves the current pol...
The GTPases Rac and Cdc42Hs control diverse cellular functions. In addition to being mediators of intracellular signaling cascades, they have important roles in cell morphogenesis and mitogenesis. We have identified a novel PAK-related kinase, PAK4, as a new effector molecule for Cdc42Hs. PAK4...
其中,USB传统纯电话业务模型,有可分为直接线控制模型(Direct Line Control Model)、抽象控制模型(Abstract Control Model)和USB电话模型(USB Telephone Model),本文所讨论的虚拟串口就属于USB传统纯电话业务模型下的抽象控制模型。 参考资料: 1. 虚拟串口驱动:https://www.elecfans.com/soft/Mec/2023/202310092263644...
The protein encoded by this gene is a small GTPase of the Rho-subfamily, which regulates signaling pathways that control diverse cellular functions including cell morphology, migration, endocytosis and cell cycle progression. This protein is highly similar to Saccharomyces cerevisiae Cdc 42, and is ab...
