* \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.
|
|
*
|
|
* Connections to the device are simple:
