* * \section SSec_Description Project Description: * * Firmware for an AVRStudio compatible AVRISP-MKII clone programmer. 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 promted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio. * * Note that this design currently has several limitations: * - Minimum target clock speed of 500KHz due to hardware SPI used * - No reversed/shorted target connector detection and notification * * On AVR models with an ADC converter, ACC 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 at a fixed 5V level. * * \section SSec_Options Project Options * * The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value. * * * * * * * * * * * * * * * * * * * * * * * * * * * *
