The functions and performance of this AVR emulator are the same as those of AT AVR JTAG ICE The mkll emulator is exactly the same: Simulation function: supports full-speed operation, single-step debugging, breakpoint debugging and other debugging methods, and can view 10 states, variable data, etc. Simulation performance: Use USB interface for simulation debugging, single-step debugging, breakpoint debugging, the response speed is quite fast, and the simulation is extremely fast! Programming function: can burn fuse bits, encryption bits, EEPROM and other functions, etc. Programming performance: Use USB interface for ISP download, medium-speed programming: JTAG download, extremely fast programming. Supported software: Directly support AVRStudio, AVR32 Studio, WINAVR (GCC), IAR Support debug files and burning files generated by ICCAVR, CVAVR, IAR, etc. Supported models: The device models supported by this AVR emulator are the same as those of the AT AVR JTAG ICE mkll emulator: Support all AVRs with debugWIRE interface, JTAG, and interface Support AVR32 (Note: Supported voltage range: 2.1V-5.5V) Support low-voltage devices (support the corresponding low-voltage models of the above devices, such as AVRs with suffixes "L" and "V": ATmega16L, ATmega48V) New devices are constantly increasing, click to view more new supported device lists: UC3, , , Tiny, Xmega Support simulation debugging and download programming: The connection interface between this AVR emulator and PC is exactly the same as that of ATAVR JTAG ICE mkll emulator: The USB port uses PDIUSBD12 to achieve high-speed USB communication. Serial port, suitable for PCs with tight USB ports. Each device has an ID, and one PC can connect multiple devices. Different batches may have differentscreen printing/appearance, but it not affect the use Colour:Blue Material:Plastic + Electronic Components Package Contents: 1 x AVR downloader 1 set x accessories (random colors, don't accept the specified color) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
