The Vidstrom Labs Guide to Advanced Arduino Due Internals

This isn't a book for the faint of heart. The Arduino Due is quite a different beast compared to the more common Arduino Uno. It uses the Arm Cortex-M3 microcontroller SAM3X8E from Microchip (formerly Atmel). Learning the internals of the Due is a possible bridge from the more straightforward world of the Arduino into the much more complicated world of Arm. If you've come this far, I assume that you have ambitions way beyond using only the Arduino API. This is a journey into the world of Arm.

Coverage includes the internals of:

• Uploading over the programming port and the native port
• The boot sequence from power-on to setup() and loop()
• The clock tree
• Digital I/O, including glitch filtering and debouncing
• Interrupts, including SysTick and the NVIC
• Flashing and debugging via JTAG
• Bare metal development for the Due with the GNU Arm Embedded Toolchain and makefiles
• Time and delays
• The Serial object
• analogWrite()
• analogRead()
• The USB stack including the UDD, the USB Core, PluggableUSB, PluggableUSBModule, the HID Library, the Mouse Library, and the Keyboard Library
• The SPI Library
• The Wire Library (I2C)
