This project will enable the USB AVR series of + * microcontrollers to act as a clone of the official Atmel AVRISP-MKII programmer, usable within AVRStudio. In its + * most basic form, it allows for the programming of 5V AVRs from within AVRStudio with no special hardware other than + * the USB AVR and the parts needed for the USB interface. If the user desires, more advanced circuits incorporating + * level conversion can be made to allow for the programming of 3.3V AVR designs. + * + * This device spoofs Atmel's official AVRISP-MKII device PID so that it remains compatible with Atmel's AVRISP-MKII + * drivers. When prompted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio. + * + * Note that this design currently has the following limitations: + * - Minimum ISP target clock speed of 500KHz due to hardware SPI module prescaler limitations + * - No reversed/shorted target connector detection and notification + * - A seperate header is required for each of the ISP, PDI and TPI programming protocols that the user wishes to use + * + * On AVR models with an ADC converter, AVCC should be tied to 5V (e.g. VBUS) and the VTARGET_ADC_CHANNEL token should be + * set to an appropriate ADC channel number in the project makefile for VTARGET detection to operate correctly. On models + * without an ADC converter, VTARGET will report a fixed 5V level at all times. + * + * While this application can be compiled for USB AVRs with as little as 8KB of FLASH, for full functionality 16KB or more + * of FLASH is required. On 8KB devices, ISP or PDI/TPI programming support can be disabled to reduce program size. + * + * \section Sec_ISP ISP Connections + * Connections to the device for SPI programming (when enabled): + * + * <table> + * <tr> + * <td><b>Programmer Pin:</b></td> + * <td><b>Target Device Pin:</b></td> + * <td><b>ISP 6 Pin Layout:</b></td> + * </tr> + * <tr> + * <td>MISO</td> + * <td>PDO</td> + * <td>1</td> + * </tr> + * <tr> + * <td>ADCx <b><sup>1</sup></b></td> + * <td>VTARGET</td> + * <td>2</td> + * </tr> + * <tr> + * <td>SCLK</td> + * <td>SCLK</td> + * <td>3</td> + * </tr> + * <tr> + * <td>MOSI</td> + * <td>PDI</td> + * <td>4</td> + * </tr> + * <tr> + * <td>PORTx.y <b><sup>2</sup></b></td> + * <td>/RESET</td> + * <td>5</td> + * </tr> + * <tr> + * <td>GND</td> + * <td>GND</td> + * <td>6</td> + * </tr> + * </table> + * + * In addition, the AVR's XCK pin will generate a .5MHz clock when SPI programming is used, to act as an external + * device clock if the fuses have been mis-set.
