Note that this is the view from the back of the connector. These pins on the Arduino have to be connected to the corresponding pins on the 6-pin connector coming from the ISP, shown below. This is used to supply power to the ISP.) (Note that you want to use the +5V pin, not the +9V pin. The other three are the Reset, +5V and Ground pins you have probably already been using. Three of them correspond to digital I/O pins, numbered 11 - 13. The six pins are called MISO, MOSI, SCK, RESET, Power and Ground. You need to connect 6 pins on the Arduino Mini to six pins on the ISP.
Two pieces of male header stip, 3 pins eachĨ AVR Studio software (from Atmel, free download).One piece of male header strip, with 12 pins.With slight variations on the process, you can bootload many different configurations of Atmel-based projects. Other than this, the procedure is the same. The Arduino Mini does not have this, so you have to make a connector cable. Regular-size Arduinos have a 6 pin connector for the ISP. It's kind of like reformatting your computer's hard drive.īootload the Arduino Mini How is bootloading the Arduino Mini different from programming other Arduinos? Reinstalling the bootloader may fix these problems. However, it is possible that under some circumstances the Arduino flash memory may become corrupted, and you may not be able to program the Arduino normally.
This is useful if you want your project to start up immediately, and especially useful if it receives serial input.
You can also download the source code and modify the bootloader yourself (see this page for more details and a link to the source). There are alternative bootloaders that eliminate these delays, including the Diecimila bootloader, the Adaboot bootloader, the LilyPad bootloader, and others. This delay also occurs when the Arduino is powered up, or after programming. The bootloader on Arduinos prior to the Diecimila imposes a 10 second delay after resetting, while it waits for information from the Arduino software.
This document explains how to bootload an Arduino mini.
