![]() now arduino will be able to find the “board definitions” when we do:.file -> preferences -> additional board manager URLS.In order to make that happen, we need to open up arduino and do: These boards aren’t supported by arduino out of the box. Once that’s loaded (via those SWD pins), we can plug the board in via USB to program and communicate with it. That binary is specific to whichever microcontroller you’re using: The arduino bootloader is a key feature of the platform: this allows arduino the IDE and compiler to load programs onto your board, so we need to first program that bootloader onto your new board.įor the ATSAMD11 and ATSAMD21 series microcontrollers, this means finding one of the cmsis-dap tools and using edbg, pyOCD or openOCD in order to load the bootloader binary on the board. No bypass caps here, but they never hurt to add. I am including ‘basics’ schematics / board layouts for each of these. we need this in order to load the bootloader. ![]()
