This project will enable the USB AVR series of  Dean Camera committed Aug 24, 2009 48 49 50 51  * 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.  Dean Camera committed Aug 17, 2009 52 53  * * This device spoofs Atmel's official AVRISP-MKII device PID so that it remains compatible with Atmel's AVRISP-MKII  Dean Camera committed Dec 14, 2009 54  * drivers. When prompted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio.  Dean Camera committed Aug 17, 2009 55  *  Dean Camera committed Aug 24, 2009 56  * Note that this design currently has several limitations:  57  * - Minimum ISP target clock speed of 500KHz due to hardware SPI used  Dean Camera committed Aug 24, 2009 58 59  * - No reversed/shorted target connector detection and notification *  60  * On AVR models with an ADC converter, AVCC should be tied to 5V (e.g. VBUS) and the VTARGET_ADC_CHANNEL token should be  Dean Camera committed Aug 25, 2009 61 62 63  * 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. *  Dean Camera committed Dec 03, 2009 64  * When compiled for the XPLAIN board target, this will automatically configure itself for the correct connections to the  65  * XPLAIN's XMEGA AVR, and will enable PDI only programming support (since ISP and TPI modes are not needed).  Dean Camera committed Dec 14, 2009 66 67  * * While this application can be compiled for USB AVRs with as little as 8KB of FLASH, for full functionality 16KB or more  68  * of FLASH is required. On 8KB devices, ISP, PDI or TPI programming support can be disabled to reduce program size.

Define Name:Location:Description:
RESET_LINE_PORTMakefile CDEFSPORT register for the programmer's target RESET line. Ignored when compiled for the XPLAIN board.
RESET_LINE_PINMakefile CDEFSPIN register for the programmer's target RESET line. Ignored when compiled for the XPLAIN board.
RESET_LINE_DDRMakefile CDEFSDDR register for the programmer's target RESET line. Ignored when compiled for the XPLAIN board.
RESET_LINE_MASKMakefile CDEFSMask for the programmer's target RESET line on the chosen port. Must not be the AVR's /SS pin, as the * target pins are tri-stated when not in use, and low signals on the /SS pin will force SPI slave mode when the  Dean Camera committed Dec 03, 2009 232 233  * pin is configured as an input. When in PDI programming mode, this is the target clock pin. * Ignored when compiled for the XPLAIN board.
VTARGET_ADC_CHANNELMakefile CDEFSADC channel number (on supported AVRs) to use for VTARGET level detection.
ENABLE_ISP_PROTOCOLMakefile CDEFSDefine to enable SPI programming protocol support. Ignored when compiled for the XPLAIN board.
ENABLE_PDI_PROTOCOLMakefile CDEFSDefine to enable XMEGA PDI programming protocol support. Ignored when compiled for the XPLAIN board.
ENABLE_TPI_PROTOCOLMakefile CDEFSDefine to enable 6-PIN ATTINY TPI programming protocol support. Ignored when compiled for the XPLAIN board.
PDI_VIA_HARDWARE_USARTMakefile CDEFSDefine to force the PDI protocol (when enabled) to use the much faster hardware USART instead of bit-banging to * match the official AVRISP pinout. This breaks pinout compatibility with the official AVRISP MKII (and requires * seperate ISP and PDI programming headers) but increases programming speed dramatically. * Ignored when compiled for the XPLAIN board.
TPI_VIA_HARDWARE_USARTMakefile CDEFSDefine to force the TPI protocol (when enabled) to use the much faster hardware USART instead of bit-banging to * match the official AVRISP pinout. This breaks pinout compatibility with the official AVRISP MKII (and requires * seperate ISP and TPI programming headers) but increases programming speed dramatically. * Ignored when compiled for the XPLAIN board.
