RPI Pico is joining the world of microcontrollers // Chip design, PIO, Neopixel WS2812, C/C++ SDK

#raspberrypi #pico #pio
We will go through 3 trends that are exciting with the launch of Raspberry PI's Pico microcontroller board. Firstly, the RP2040 is a custom chip and we will discuss some practical toolchains that are available for designing a custom chip and how this process is becoming more affordable and accessible. Secondly, we will use the native C/C++ SDK to run the blinky and I2C bus scan example and see how the toolchain and documentation are all open-source and user-friendly. Lastly, we will scratch the surface of what is a PIO with a simple I2C PIO example along with running WS2812 Neopixels with PIO.
