ISP Shield for Arduino: Upgrade Your AVR Programming Experience

The ISP Shield is an essential Arduino accessory that transforms your Arduino into an AVR ISP programmer. It allows you to easily burn bootloaders onto new AVR chips directly from the Arduino programming environment, using a built-in ZIF socket or connecting to external boards. Designed by Evil Mad Scientist, this kit costs $12.95 and includes all necessary components like the ZIF socket and a 16MHz crystal. The ISP Shield streamlines the programming of Optiboot and other bootloaders for enhanced performance across various Arduino models.

  1. ISP Shield for Arduino24 July, 2013 Short description of the ISP (In-System Programmer) Shield for Arduino

  2. Why would you want one • The ISP Shield is an Arduino “shield” (daughtercard) that makes it easier to use your Arduino as an AVR ISP programmer. It can be used to burn bootloaders onto new AVR chips, from directly within the Arduino programming environment, either in the on-board ZIF socket or on an external target board. More generally, it can also be used as a general-purpose AVR ISP programmer, using avrdude with the programmer type specified as “avrisp.”

  6. Where can I get this one • This kit is made by Evil Mad Scientist: • http://shop.evilmadscientist.com/productsmenu/tinykitlist/253 • Cost is $12.95, and includes all parts, ZIF socket, and 16mhz crystal • Hardware design is based on the Fritzing tutorial: • http://fritzing.org/projects/arduino-isp-incl-shield/

  9. Optiboot • Optiboot is an easy to install upgrade to the Arduinobootloader within Arduino boards. It provides the following features: • Allows larger sketches. Optiboot is a quarter of the size of the default bootloader, freeing 1.5k of extra space. • Makes your sketches upload faster. Optiboot operates at higher baud rates and has streamlined programming. • Adaboot performance improvements. Optiboot runs your sketches sooner, with no watchdog issues. • Compatible with 168 and 328 Arduinos including Lilypad, Pro, Nano • Believed to work with ATmega1280 ("Mega"), ATmega644 ("Sanguino"), and ATmega1284. • Optiboot is now installed by default on the Arduino Uno. It can be installed on all older mega8, 168 or 328 based Arduinos.

  10. How to program Optiboot • Select the appropriate Optiboot board type (or non-Optiboot if you want to change back) • Connect your Arduino to an ISP programmer • Use the 'Burn Bootloader' item in Arduino. • You can then upload sketches as normal, using the Optiboot board type.

  11. How to Upload Programs • The ArduinoISP sketch mimics the Atmel AVRISP programmer. You can use avrdude to upload compiled programs to an ATmega168/ATmega328 via the ISP Shield 2.0 ZIF socket or either of the ISP headers. With the Arduino IDE, you can upload sketches with the ISP Shield by pressing and holding the shift key before clicking the Upload icon. Normally when you hover the mouse over the icon you will see "Upload". When holding the shift key it will show "Upload Using Programmer."
