AEMQ notes for software development:

  • Install Atmel Studio 6.1 update 1.1 (build 2674), without .NET 4.0 and MSVS Shell: http://www.atmel.com/tools/studioarchive.aspx
  • During installation, you should be prompted to first install Atmel USB drivers, which are required
  • After installing, open Atmel Studio and start a new example project
  • Choose the project for the SAM4S Xplained Pro Starter Kit
  • Edit the main.c main() function to look like this: 
     int main( void ) 
 {
 	volatile int i;
 	board_init();
 	sysclk_init();
 
 	for(;;) 
 	{
 		if( i == 1000000 )
 		{
 			ioport_toggle_pin_level(LED_0_PIN);
 		}
 		i = (i + 1) % 2000000;
 	}
 }
  • Now, plug a USB A to micro USB A into your computer and into the DEBUG USB port on the Atmel Xplained Pro board
  • The green power light should come on
  • Wait if any drivers need to be installed
  • Hopefully Atmel Studio will detect the SAM4S -- toward the top right of the IDE, you should see SAM4SD32C as the device.
  • The programmer should be set to SWD on EDBG. You may need to set this manually by clicking on device programming.
  • Also, make sure your programming/debug settings are such that the board will boot from Flash 0.
  • The programming clock can be any speed that is "slow enough"
  • Press the green debug arrow in Atmel Studio to compile, load, and launch the program in debug mode on the board
  • If successful, the yellow LED0 will start blinking (LED0, not the status LED!)
  • If this doesn't work, ask someone what you are doing wrong and/or update this guide
  • After you have completed these steps, try running FreeRTOS blinky by downloading the release here: https://github.com/mattkgross/AEMQ/releases
  • Once these both work, you are ready to start developing code for AEMQ
  • FreeRTOS Tutorial: http://www.freertos.org/tutorial/
  • FreeRTOS Overview: http://aosabook.org/en/freertos.html
  • Setup your GitHub account and install git
  • Fork the AEMQ repository so you have your own copy to work on
  • Commit changes often
  • Create a pull request when you are ready to have your changes picked up in the main repo.
  • Note that we will perform a code review first.
  • Rework any changes until they are approved. See https://help.github.com/articles/using-pull-requests
  • Start working on the next task
  • A good reference for git: http://git-scm.com/book/en/Getting-Started
