 |  | AT91-AN01: Using the Two-wire interface (TWI) in Master Mode on AT91SAM Microcontrollers (32 pages, revision B, updated 08/07) This application note is an aid for developers in the design of a system using the Two-wire Interface (TWI) of Atmel's AT91SAM family of microcontroller products with Atmel's Two-wire Interface slave devices and I2C-Bus compatible slave devices. It describes the connection with a digital temperature sensor (LM75), a Real Time Clock (DS1337), a Graphic LCD Module(PCF8558) and a 1Mbit Two-wire Serial EEPROM (AT24C1024). |
| | AT91SAM Internet Radio (41 pages, revision A, updated 05/07) Describes an Internet Radio software that can run either on SAM9260-EK or SAM7X-EK evaluation board. Includes a description of an add-on board which contains a stereo audio codec, an LCD display and three push buttons. |
| AT91SAM7S64 USB Certification (34 pages, revision A, updated 2/06) This Application Note describes the USB certification process for the AT91SAM7S64 microcontroller that contains a USB V2.0 Full Speed Device. It describes the full USB peripheral environment required for USB-IF compliancy.  | |
| | AT91SAM9 LCD Controller (23 pages, revision B, updated 7/07) Explains how to connect the AT91SAM9 LCD Controller to an STN or TFT display. |
| | Using the Serial Peripheral Interface with AT91SAMxx Devices (11 pages, revision B, updated 8/06) Describes initializaton of the SPI, main SPI features are summarized and characteristics that may be difficult to use are detailed. A software example of an interconnection between two SPIs is also described. |
| AT91 USB CDC Driver Implementation (20 pages, revision B, updated 7/09) Explains how to implement the Communication Device Class (CDC) driver on AT91 microcontrollers. Describes a device-side USB framework that enables rapid development of USB-compliant class drivers such as Mass Storage Device class or the Communication Device Class. Source code can be found in the Software packages | |
