How to enable exception handling on the Arduino Due?
While the question here gives some hints, the solution provided there does not directly work on the Due, since it uses a different compiler and toolkit. Also, the Due has more than enough flash for mo …

How to enable exception handling on the Arduino Due?
First, we must make sure the "-fno-exceptions" compiler flag is overwritten with "-fexceptions". In addition, we must link a separate library that includes the compiler support functions for stack unw …

Arduino DUE wheel encoder
You can use an interrupt handler to measure frequency. Works quite well.
volatile int32_t _ticks = 0;
public void FrequencyIsr()
{
_ticks++;
}
// Add this to setup()
// Mode can be FALLING, RISIN …

Memory allocation on Arduino Due never returns NULL
I think I found a workaround. It relies on the fact that on simple program architectures such as the one used on most microcontrollers, the heap grows upwards while the stack grows backwards.
const in …

Memory allocation on Arduino Due never returns NULL
I'm working on a project that uses quite a bit of RAM to store and analyze data that is sent from the PC. The program heavily relies on malloc/free, which normally works just fine. However, if the dat …

Is there a good reference for Arduino Due memory architecture and usage?
Yes, the Arduino Due uses a flat memory model with a single address space for Flash and RAM. Therefore all constant data sits in flash and does not need to be copied to RAM at startup, like the AVR-ba …
