#OPENSPRINKLER PI WIRELESS CODE#

If you've been using this in C or MicroPython as an indicator you'll need to change your code to take advantage of the new hardware options. The most obvious is that the onboard LED is no longer connected to the RP2040's GPIO pins, instead working through the Wi-Fi chip's own GPIO. There are some minor differences between the W and the original Pico beyond adding wireless support.

#OPENSPRINKLER PI WIRELESS LICENSE#

Usefully, Raspberry Pi has negotiated a free commercial-use license for the normally non-commercial libcyw43, so you can continue to build commercial hardware using the Pico W or even build your own boards around the combination of the RP2040 and the CYW43439. Currently the wireless stack is based on the lwIP TCP/IP implementation, using libcyw43 to control the wireless hardware.

Although this first release only supports Wi-Fi, Raspberry Pi has noted that it might add Bluetooth support in the future. The chip used to add Wi-Fi to the Pico W, the Infineon CYW43439, also supports Bluetooth and Bluetooth Low Energy (LE). The device is a 21mm by 51mm circuit board, with 40 pins ready to be either fitted with header pins for use on a breadboard or connected directly to sensors and actuators. As well as a RP2040, the Pico has an additional 2MB of flash storage for your code and the device's firmware. Designed to be built into hardware, each chip also offers 26 GPIO pins, with a host of additional controller hardware including eight programmable I/O state machines.Īs well as selling RP2040s to customers to build into their own devices (I have one that's a 4x4 LED backlit keyboard and another that's a customisable e-paper badge), Raspberry Pi uses it in its own Pico boards - low-cost devices aimed at makers and other hardware hobbyists.

It's also the first system-on-a-chip (SoC) device from the company, which up to now had been using off-the-shelf processors.īased around a 133MHz dual-core ARM Cortex M0 running at 133MHz, it has 264KB of on-chip memory.

Raspberry Pi's RP2040 microcontroller is an interesting piece of silicon, providing a balance of power and flexibility.
