5) shows the class notifications supported by the Abstract Control Model. Indicates to DCE if DTE is present or not.This signal corresponds to V.24 signal 108/2 and RS232 signal DTR. #Efm32 Usb Cdc Serial Port full#The device ignores the value of this bit when operating in full duplex mode. This signal corresponds to V.24 signal 105 and The following table defines control signal bitmap.Ĭarrier control for half duplex modems. SET_LINE_CONTROL_STATE control signal bitmap This request generates RS-232/V.24 style control signals. Line coding structure 3.1.3 Set Control Line State the world's most energy friendly microcontrollers This request allows the host to find out the currently configured line coding. 4) defines the line coding properties.ĭata bits (5, 6, 7, 8 or 16). This request allows the host to specify typical asynchronous line-character formatting properties. These class-specific requests are used by the host to configure and receive status info from the CDC device. RS232 signal used to tell the DCE device the DTE device is now present. Requests current DTE rate, stop-bits, parity, and number-of-character bits. Abstract Control Model RequestsĬonfigures baud rate, stop-bits, parity, and number-ofcharacter bits. The class requests and class notifications supported are listed in Table 3.1 (p. The Abstract Control Model subclass of CDC and bridges the gap between legacy modem devices and USB devices, enabling the use of application programs designed for older modems. The CDC is used primarily for modems, but also for ISDN, fax machines, and telephony applications for performing regular voice calls. The USB communications device class (CDC) is a composite USB device class, and the class may include more than one interface. the world's most energy friendly microcontrollers 3 USB Communication Device Class AN0065 EFM32 as USB Device - Provides a description of the EFM32 USB Device stack.AN0046 USB Hardware Design Guide - Provides recommendations on hardware design for implementing USB host and device applications using USB capable EFM32 micro-controllers.AN0822 SIMPLICITY STUDIO USER’S GUIDE - Provides a description of the Simplicity Studio IDE features and environment.Provides an implementation example on porting LUFA USB CDC on SiM3U1xx MCUs.
