== Firmware ==
=== Use Arduino as ISP ===
There is sketch in the arduino IDE, for the wiring in the description should be: 
[[File:Avr-isp-test.png|thumbnail]]
{| class="wikitable sortable"
|-
! pin name !! not-mega !! mega(1280 and 2560)

upload the sketch and use Avrdude to test it, and should success on following picture 

=== Burning bootloader ===
* Tools you will need:
* USBASP programmer: in our test, it's much faster than the USBtinyISP, don't know really know why, burning with usbasp only need 5-10 seconds, but usbtinyisp need around 1-2 minutes
* ISP 10-6 Pins converter: It's really helpful to convert ISP 10 pins to ISP 6 pins, and also help you to remember the pins for ISP-6, because the silk print indicate it! Works for all the ISP-10 programmer.And Arduino only have 6-pin ISCP connector
* Your arduino board: The MCU is already on the board and need to be programmed.
* Connect the programmer with the converter like below, only need to remember MISO is always to PIN1: 
* Connect the board with USBASP to your laptop and burn, no need USB connect to the board anymore

* You will get both error message when you burning uno and mege with usbasp programmer, but don't worry, it's just a "warning" message instead of "error" message, nothing is going wrong actually. (This is tested with Arduino IDE 1.0) 
To verify the IC is successfully burnned, simply upload sketch from examples - basics - blink to see the Status LED 13 on the board should start to blink after upload sketch. (The status LED 13 should be only power ON for UNO and unusual blinking for MEGA but not smoothly blink after uploading bootloader)

=== Burning bootloader with other programmer, directly via hex file ===
==== Use Avrdudess programming ====
You can find the avrdude we used here.[[programmer]] 
<gallery widths =300px heights =300px>

File:arduinobootsetup.jpg
File:Avrdudess_uno.jpeg | Flash use avrdudess GUI

==== Fuse bit ====
* Atmega328p UNO
hfuse - 0xDE
lfuse - 0xFF
efuse - 0x05
* Lock bit
# BLB12 BLB11 - app to bootloader
# BLB02 BLB01 - bootloader to app
# LB2 LB1 - visit control to Flash, EEPROM, Fuse (hfuse, lfuse, efuse) and Boot Lock Bit
* bootloader area NOT visit-able - lfuse set to 0x0F
* bootloader area visit-able - lfuse set to 0x3F
=== Deploy arduino ===
* complied code and find file for example named "nrf24duino_start.ino.with_bootloader.hex" in folder C:\Users\Administrator\AppData\Local\Temp\arduino_build_981353
* flash write into MCU
* pro mini fuse set, L:0xFF, H:0xDA, E:0xFD, LB:0x0F

== Tips ==
=== Fix auto upload manually ===
* Hold down the reset button when IDE show "compile ..."
* Release the reset button when IDE show "uploading ..."

== Extension ==
* [http://khanning.github.io/scratch-arduino-extension/index.html Scratch extension]
== Documents ==
* STM32 Nucleo Toolchain use manual
* [http://electronut.in/stm32-start/ Eclipse extension with GCC toolchain]

* See how to make minimal Arduino on this page [[DIY-arduino]]
