The great thing about tech is that things never stand still. It wasn't long after the previous newsletter went out, that I started playing with the new $4 Raspberry Pi Pico. It is a cheap and cheerful microcontroller board that can be programmed in C/C++ and MicroPython. But that isn't all. Read on to find out if AMD's RDNA GPU can save the Samsung Exynos processor, plus take a look at an HDMI to USB-C video capture device from ATEN.

Raspberry Pi Pico - Review, Getting Started with MicroPython, and programming with C & C++

The Raspberry Pi Foundation seems to be searching for a new vision and so has decided to get into the crowded microcontroller market with the Raspberry Pi Pico. Based on a dual-core Cortex-M0+ microcontroller, it runs MicroPython or C/C++ and is designed for makers, enthusiasts, and hobbyists. Here is my review and getting start guide.

In my previous video, I showed you how to use the Raspberry Pi Pico with MicroPython. In this video I take a took at using C or C++ and cover how to run code on the second Cortex-M0+ core.

Which Raspberry Pi model is best for you? Way back there was just one model but over the years the number of options has increased, now including microcontrollers and desktop computers. Let’s take a look at what is available, so you can pick the right Raspberry Pi for your needs.
