SatCat5 includes C++ software libraries for:
- Sending and receiving Ethernet frames over nearly any interface.
- Sending and receiving ARP, ICMP, IP, and UDP messages.
- Configuring a managed SatCat5 Ethernet switch.
- Configuring various SatCat5 I/O peripherals (e.g., I2C, MDIO, SPI, or UART).
SatCat5 also includes Python software libraries for some of these functions.
The core functions are as generic as possible, designed for use on bare-metal microcontrollers, FreeRTOS, Linux, or Windows. We provide hardware abstraction layers for several of these platforms.
Since many of these platforms are extremely constrained (64 kiB RAM or less), the design has minimal dependencies (even printf is too large) and all objects can be statically allocated. Heap allocation is not used in the core, but is an option in hardware abstraction layers intended for desktop platforms.
For more information, refer to the README.
SatCat5 is intended for use on tiny microcontroller and unconventional interfaces, like SPI and UART. Very few operating systems allow the required level of customization, so we built a simple stack from scratch.
SatCat5 does not currently support TCP/IP, but may add lwIP support in a future release.
