RUNSTDBY = 1; Not sure if different for other boards that use SAMD21. The Cortex-M0+ Devices Generic Users Guide is targeted at application software developers. Note the cortex-debug extension is only useful if you have a J-Link in you workflow. If you want to step your SAMD21-development game up, consider grabbing an ARM debugger/programmer and interfacing it with the SAMD21's Cortex Debug port. It should trigger the camera as long as the light beam is broken (HIGH-signal) and it should be possible to shot additional images after the last trigger signal from the light barrier.

In-Circuit Serial Programmer™ (ICSP™) Guide (DS30277) This document contains helpful design guidelines for successful ICSP programming. The SAM D21 microcontrollers are supported with a full suite of program and system development tools, including C compilers, macro assemblers, program debugger/simulators, programmers and evaluation kits. AT6491: Getting Started with SAM C21 [APPLICATION NOTE] Atmel-42466A-Getting-Started-with-SAM-C21_ApplicationNote_062015 7 7 Figure 4-2. However, when going through the insanely long datasheet, I noticed that there are no clearly defined pin numbers and SAMD21 Mini/Dev Breakout Hookup Guide Both boards have similar feature sets – they equip the ATSAMD21G18 with a USB interface for programming and power, then surround it with an RTC crystal, 600mA 3. Uses load_image instead of program. Depending on the task it's given, the SAMD21's core will usually consume between 3-17mA. There appear to be 3 implemented in the version of SAMD21 used on the Adafruit Feather M0 (TC3 - TC5). Programming Questions.
