Bare Metal: Pico and CYW43

The &ldquo;W&rdquo; signifies that the board includes wireless. Interestingly, the wireless chip is an Infineon CYW43439 ) which is itself a microcontroller running its own ARM Cortex chip (M3). The Pico&rsquo;s USB device includes another ARM microcontroller. So, with the dual Cortex (or Hazard) chips that are user programmable, and the 8 PIOs, these devices really pack a punch. As a result of…
