Re: bare metal Raspberry Pi Zero port Post by dhylands » Tue Jul 31, 2018 7:05 pm I noticed that on the ESP32 that using rshell doesn't seem to do a soft-reset at the repl, while pressing Control-D does.
Though if I was doing it again I'd probably have a bare-metal chip running the timing critical, and throw a cheap arm core on there running linux just to make life easier. And I'm pretty sure I could probably do away with the bare-metal and just pin some userspace code to a core and it'd work just as well. Edit: *'days' -> 'years'
Raspberry Pi (/ p aɪ /) is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. Early on, the Raspberry Pi project leaned towards the promotion of teaching basic computer science in schools and in developing countries.
Bare Metal GPIO on the Raspberry Pi The Raspberry Pi is classically used as a single board computer running Linux but it also offers the possibility of using the board without Linux (known as bare metal development).
The TOUTPI2 is a non-invasive I2C adapter complete with level shifter providing you with a 5V I2C port for use with any of our I2C devices. The I2C port points outward toward the outside edge of the board, and terminates directly above the HDMI port.

The new Raspberry Pi 4 Model B is a low-cost computer that runs on a 1.5 GHz 64-bit quad-core Arm Cortex-A72 processor. It’s a device that many millions of people worldwide use, and so it’s exciting to write bare metal code for it. Imagine that somebody else might one day use your OS!
