The distance between the circuit to be programmed and the computer is limited by the length of USB cable - it must usually be less than 180 cm. This can make programming devices deep in machinery or cabinets a problem. ICSP programmers have many advantages, with size, computer port availability, and power source being major features.
Ever since its first release, all software source code (firmware, PC application) and hardware schematics are open to the public. This makes it relatively easy for an end user to modify the programmer for use with a non-Windows operating system such as Linux or Mac OS. It also creates much DIY interest while allowing clones to be created easily.
The in-system programming (ISP) programming method is functionally performed through SPI, plus some twiddling of the Reset line. As long as the SPI pins of the AVR are not connected to anything disruptive, the AVR chip can stay soldered on a PCB while reprogramming. All that is needed is a 6-pin connector and programming adapter.
debugWIRE is activated by setting (programming to zero) of the fuse DWEN (debugWIRE enable), normally located in the high fuse byte. After this action the /RESET pin function isn't available anymore and the ISP protocol cannot be used. debugWIRE can be disabled with any of the mentioned debuggers by sending a special reset command that disables temporarily the debugWIRE function and reenables ...

C Programming for Microcontrollers, a book for learning to program AVRs using C, was written for the Butterfly as development platform. [6] [7] The Butterfly Logger is an open source data logger based on the AVR Butterfly. [8] The Butteruino project is a set of libraries to integrate the AVR Butterfly with the Arduino development environment. [9]
If you're using broadband (cable) internet and you can't connect, try the following troubleshooting steps in the order listed until you get up and running again. 1.

Freeware ISPF-style editors for Windows include SPF/SE and SPFlite. In 1994 IBM introduced a built-in downloadable client program called the ISPF Workstation Agent (WSA) [a] that can install and run on OS/2, Windows and selected UNIX workstations; the z/OS version of ISPF only includes WSA for Windows and selected UNIX workstations.
