SDCC

SDCC is a free and open-source compiler for the C language that is primarily used to develop applications for microcontrollers. Its website, sdcc.sourceforge.net, provides users with access to the latest version of the software, as well as helpful documentation and community support.

SDCC supports a range of microcontroller architectures, including 8051, Z80, Z180, Rabbit 2000/3000, and XC800. It also includes a number of standard C libraries, making it easy for developers to write and compile code for these platforms.

One of the key features of SDCC is its ability to generate small code size and efficient memory usage, which is particularly important for microcontrollers with limited resources. Additionally, SDCC provides a number of optimization options that can help developers further optimize their code for specific platforms.

The SDCC community is active and helpful, providing users with access to a number of resources including mailing lists, forums, and code examples. SDCC is a powerful tool for developers looking to create microcontroller applications using the C language.
