Arne Vidstrom 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 portThe boot sequence from power-on to setup() and loop()The clock treeDigital I/O, including glitch filtering and debouncingInterrupts, including SysTick and the NVICFlashing and debugging via JTAGBare metal development for the Due with the GNU Arm Embedded Toolchain and makefilesTime and delaysThe Serial objectanalogWrite()analogRead()The USB stack including the UDD, the USB Core, PluggableUSB, PluggableUSBModule, the HID Library, the Mouse Library, and the Keyboard LibraryThe SPI LibraryThe Wire Library (I2C)
