PX-HER0 ARM Cortex Development Board and Ecosystem
Piconomix is offering an embedded Arm Cortex-M0 development board that is aimed at the education, beginner maker, and enthusiast crowd. The PX-HER0 is a development board with an ecosystem of sourcing materials for learning the entire ARM structure through an open-source C library and full documentation.
The Basics of the Board
The PX-HER0 is a low-power board, running an STM32 MCU with an Arm Cortex-M0 core. There is an LCD Display, that is viewable even in direct sunlight, and the entire package is lightweight and very functional.
Mass Storage
To activate the bootloader, a double-tap of the RESET button, and the mass storage drive HERO-BOOT appears in the host computer. Drag and Drop are active and the UF2 file can be dragged right to the drive.
The Ecosystem
The ecosystem for the PX-HER0 is backed by an extensive C Library and documentation on GitHub Piconomix repo. There is an Arduino tutorial for the HER0 board explaining how to use it with the Arduino Core STM32 library.
The documentation found on FwLib page at Piconomix.com includes:
