#microcontroller

Dmitry is back again with another minimal computer. Last time he managed to boot #Linux on an #Intel4004¹. Now he wants to run #vi, #gcc, and #make, ends up doing it on a tiny #STM #microcontroller with a luxurious 32K of flash and 8K of RAM. The 4004-based machine took a *week* to boot, this one takes just a minute!

It's again made possible w/ #MIPS #emulation. The overclocked host CPU emulates a MIPS #R3000 at 1.65MHz with FPU disabled.

Hey, #programming #electronics #arduino #microcontroller folks. Say I have a device like a joystick which generates its own data and clock signals, and I want a Pi Pico 2 to capture inputs from it.

What should the flow of that program look like? Do I just capture 2x the length of a full packet, find the single whole packet in it, read that and move on? How would you go about detecting and reading every individual packet?

Boosts and all comments welcome.

Pretty interesting attempt at a minimal OS designed to run literally anywhere.

#TexasInstruments just released a #microcontroller so small you could lose it in your pocket. The #MSPM0C1104 is only 1.38 mm², smaller than a grain of rice, but still acts as a tiny computer. It has a 32-bit processor running at 24 MHz, with 1KB of memory and 16KB of storage. It can even sense things like temperature or movement. Power use is minimal, running on just 87μA per MHz and dropping to 5μA in standby. This makes it ideal for tiny devices that need to last a long time on small batteries. It is also built to handle extreme conditions, working in temperatures from –40°C to 125°C. ti.com/product/MSPM0C1104
