Sorting through my drawer jammed full of project detritus, scads of Raspberry Pi units of every gen short of Pi5, odd boards of my own creation, etc. I’m bringing some #gridfinity order to this drawer and weeding out the junk.
Found this unit in the mess. I had to look it up to remember what it was and I’m guessing I never even fired it up back in the day (figured a project to use it would materialize).
It’s a 2015 era CHIP computer from NTC.
1.38 Millimeter Microcontroller
In the tiny world of #ARM (and many other) #microcontrollers, everything is an "address": in-CPU status and control registers, on- and off-chip peripheral data and control registers, I/O ports, and other hardware bits are accessed via a memory map. While this address abstraction is a refined software view of the raw hardware, it is still a pointer-level view of the world, the lowest of programming abstractions.
As MCUs grow in power and the software that run on them grow in size, higher level abstractions become necessary. Indeed, most software on MCUs are now implemented in C and other higher-level languages, with assembly confined to small portions of libraries and RTOSs.
In the #UNIX world, everything is a "file". This elegant, uniform expression reached its zenith in #Plan9, the grownup UNIX. I believe the file abstraction offers numerous benefits to modern MCU #programming.
ESP8266 (and ESP32)
These little modules have taken hobby electronics by storm, so of course I grabbed a few of them and have been hacking away quietly on both the ESP8266 and the ESP32.(...)
