Library Blog
USB Device Library presents the user set of functions required to handle USB device peripheral. A embedded user application program uses API defined in this library to access USB device peripheral. The library has set of functions implemented within library and also uses set of callback functions which will be implemented by application designer outside of the library. Library internaly handles standard device requests, leaving the user to process other requests.
As example of use of this library, following USB device classes are implemented:
HID (Human Interface Devices) class with mouse functionality
MSC BOT (Mass Storage - Bulk Only Transport) class.
CDC (Communications Device Class) class.
USB Device Library features following functions:
USBDev_Init
USBDev_IntHandler
USBDev_GetDeviceState
USBDev_StallEndpoint
USBDev_CtrlStall
USBDev_ClearStallEndpoint
USBDev_RegisterGetDescriptorHandler
USBDev_RegisterEventHandler
USBDev_RegisterSetupReqHandler
USBDev_RegisterDataReceivedHandler
USBDev_RegisterDataSentHandler
USBDev_ConvertStringToDescriptor
USBDev_SendPacket
USBDev_SetReceiveBuffer
USBDev_CtrlDataAck
USBDev_CtrlSendData

MUX 9 Click is a compact add-on board that contains a precise multiplexing solution. This board features the ADG1438, a CMOS 8-channel analog matrix switch with a high-speed serially controlled 4-wire interface from Analog Devices. Each switch is software-controlled (by a bit of the appropriate register) and conducts equally well in both directions, making it ideal for mux/demux applications. It is specified for a wide supply range ±15V/+12V/±5V where all channels exhibit break-before-make switching action, preventing momentary shorting when switching channels.
