Circle is a C++ bare metal programming environment for the Raspberry Pi, providing ready-tested classes and add-on libraries to control hardware features without an operating system. It supports 32-bit and 64-bit applications and includes a TCP/IP network stack, USB support, and sample programs.
Use cases
- write bare metal applications for Raspberry Pi
- build an OS kernel for Raspberry Pi from scratch
- control Raspberry Pi hardware directly without Linux
- run a TCP/IP network stack on bare metal Raspberry Pi
- develop 64-bit bare metal firmware for Raspberry Pi
- access USB devices from bare metal code
When to choose
- you need to run code on a Raspberry Pi without an operating system
- you want fine-grained control over Raspberry Pi hardware like GPIO, USB, or Ethernet
- you are building an embedded or hobby OS project on Raspberry Pi
- you need a bare metal TCP/IP stack with socket API
When to avoid
- you want to build a normal Linux application for Raspberry Pi
- you need a full-featured RTOS with scheduling guarantees out of the box
- you target hardware other than Raspberry Pi
- you prefer a C-only environment without C++ classes
