Update : Displays

Of all the things you can program, microcontrollers are the least friendly. They have no interface that a human can use. That is regrettable, especially when trying to get some feedback from your code during development. A simple LED connected to an I/O pin can already be used to provide a lot of feedback with very little hardware (and code) but it’s a very limited option. Luckily, there are lots of inexpensive display modules out there than can do a lot more than turn on and off. They do require significantly more code to operate, however. Let me help you with that.


Update : STM32H750

The STM32H750 is an interesting MCU : at 480 MHz it’s one of the fastest Cortex-M7 devices in existence but it’s also one of the least complicated because it only has one core. That also makes it cheap. And this makes it a very good chip to be proficient with.


Update : STM32H7

The H7 family of STM32 microcontrollers is, as of 2021, the most badass there is. It is based on the ARM Cortex-M7F core running at up to 550 MHz, with some chips in the family equipped with a second ARM Cortex-M4F core running at 240 MHz. How powerful is that ? Well, back when I was a kid, PC’s were equipped with Pentium MMX processors which could barely hit 200 MHz… and that was enough to run Windows 95 and first-person shooter games like Doom and Quake.


New ! Setup

The Jetson Nano is not as easy to setup as a Raspberry Pi. There isn’t a “NOOBS” SD card you can buy, stick into your Nano and be done. But then again, this ain’t a Raspberry Pi : if you’re playing with a Jetson Nano you obviously intend to work on stuff that’s too hardcore for a Raspberry Pi, and therefore it’s safe to assume you’re not afraid of the command line prompt.
