SAMD21

The SAM 15x15 is a very small Arduino development board, with the same powerful controller as the Arduino Zero: the SAMD21G18. All I/O pins are used: despite the small size, it has more I/O pins th...

Video To test the SAM15x15 board automatically, I made the tool described here. As you can see, the mechanical construction is very simple. Simple test fixture for PCB probe testing and program...

Intro To use new Arduino boards, we first have to install an appropriate package, which describes the processor and pins. The SAM 15x15 is an expansion of the Arduino Zero board; therefore, insta...

{autotoc enabled=no}Uploading sketches to the Arduino Zero (and other related boards) trough the native port is a pain in the ass. It happens quite often that the Arduino board doesn't respond...

Burning a bootloader into the ATSAMD21 This article is dated, see here how to burn a bootloader simply with a J-Link Debugger: ATSAMD21g18 Bootloader With J-link Debugger I no longer sell t...

Just for nerds This article is a comprehensive description of Arduino SAMD21 installation packages. Note that for the use of the SAM 15x15 board, you don't have to read this. Just read the quick s...

Read this first I will not duplicate what has already been described elsewhere; basic information can be found here: Arduino Zero Overview.  See HERE for a detailed description about the...

SAMD21 introduction Since 2015, there is a new powerful microcontroller available which can be programmed by the Arduino platform: the SAMD21. It is a 48MHz 32-bit ARM Cortex M0+ low power pr...
