Raspberry Pi bare metal programming environment

[Sergei G]

For those of us who, like myself, has a bunch of legacy Raspberries laying around - there is a way to use them as microcontrollers. I wish it was from an Arduino IDE, but no - a bit more complicated. 

"Circle" allows compiling a C++ program and booting it from SD card without OS, "bare metal".

PWM, I2C and many more samples are in the "samples" folder. Circle supports 32 or 64 bit CPUs. RPi5 not fully supported.
