Using the
ATAVRAUTO900
Adaptor
The AVR ISP is a compact and easy-to-use In-System Programming tool for developing
applications with AT90CAN128. Due to the small size, it is also an excellent tool for field
upgrades of existing applications. It is powered by the ATAVRAUTO102 and an addi-
tional power supply is thus not required. The AVR ISP programming interface is
integrated in AVR Studio®. An additional adaptor has to be used to program the board
using ISP or JTAG mode. The 10 pins connector is used for the JTAGICE mkII device
and the 6 pins connector is used for the AVRISP device. To plug the ATAVRAUTO900
connector to the board, the arrow (on the adaptor) has to be in front of the point (on the
board).
