Here are some frameworks for developing firmware for a number of ARM (Advanced RISC Machine) architecture single chip microcontrollers.

I am interested in alternatives to the traditional GCC development environment, so you will find here some experiments with Astrobe Oberon, Free Pascal, GNAT Ada, ARM Mbed OS, and Mikropascal for ARM microcontrollers. I am convinced that the true value of a microcontroller development environment lies in the richness of its software component libraries more than any other factor. For this reason, my own work has mostly switched to ARM Mbed OS and Mikropascal, both of which include very extensive component libraries.

News

13 March 2017 -- Moved the original GCC framework into the gcc/ subdirectory. Removed some obsolete cruft (EFM32, mbed Classic, etc.). Started adding support for developing with Free Pascal Embedded for ARM microcontrollers.
17 March 2017 -- Updated binutils to 2.28, gcc to 6.3.0, newlib to 2.5.0, and gdb to 7.12.1. Imported LEGO Power Functions Infrared Remote Control Protocol implementation.
20 March 2017 -- Cleaned up and reordered ARM.mk. Modified ARM.mk to append CFLAGS, CXXFLAGS, and LDFLAGS to RMAKEFLAGS so ensure that they are propagated to subordinate make jobs. Added lightweight_strncasecmp() to conio.c.
19 September 2017 -- Upgraded binutils to 2.29, gcc to 7.2.0, and gdb to 8.0.1.
9 April 2019 -- The framework here for using ARM Mbed OS has been greatly improved and streamlined. Compiling the OS takes quite a while, so it is now built as a library once for each target board and saved in ~/.mbedos. This speeds up building and rebuilding applications.
2 June 2020 -- Upgraded Mbed OS to 5.15.3. Also made some minor tweaks to the Mbed OS framework.
17 June 2020 -- Upgraded Mbed OS to 6.0.0.

I am available for custom system development (hardware and software) of products using these ARM microcontrollers.
