Optoisolated USB JTAG Dongle for programming and emulation Olimex AVR-USB-JTAG
AVR-USB-JTAG (complete analog of ATMEL’s AVR JTAG ICE) is development tool for programming, real time emulation and debugging for AVR microcontrollers with JTAG interface (ATmega16, ATmega32, ATMega323, ATmega162, ATmega169, ATmega128 and all other future to come).
Detailed Description
AVR-USB-JTAG have:
JTAG 10 pin connector (Atmel layout), status LED, USB type A connector.
AVR-USB-JTAG works transparently with AVRSTUDIO as it uses USB to RS232 driver inside and AVRSTUDIO just finds ATJTAGICE connected to the virtual COM port which FT232 driver installs.
AVR-USB-JTAG allow debugging on all new computers and notebooks which have no RS232 COM port and removes all problems which occur when unknown/uncertified USB to RS232 port converters are used with the original RS232 based ATJTAGICE.
AVR-USB-JTAG is optically isolated from USB port, so you can debug directly connected to 120/220VAC mains targets. AVR-USB-JTAG allows access to all the powerful features of the AVR microcontroller. All AVR resources can be monitored: Flash memory, EEPROM memory, SRAM memory, Register File, Program Counter, Fuse and Lock Bits, and all I/O modules. AVR-JTAG also offers extensive On-chip Debug support for break conditions, including break on change of Program memory flow, Program memory Break Points on single address or address range, and Data memory Break Points on single address or address range.
