uC-Makefile

A Makefile for popular Microcontrollers supporting Arduino-2.3.x (avr, attiny, esp8266, esp32 and pico boards).

If:

• You'd prefer to be using vi or emacs to the Arduino IDE
• Your preferred source tree layout differs from Arduino's
• You want to program more than one type of board at the same time
• You want more control over the build process than it gives you (e.g., compiler optimisation levels)
• ... then this is for you!

Configuration

Install the makefile fragments in somedir.

Create a Makefile in your sketch directory, such as this, for a TI Launchpad:

BOARD := MSP-EXP430FR5739LP
include msp430.mk

For an Arduino Uno, the equivalent would be:

BOARD := uno
include avr.mk

A minimal Makefile must specify a BOARD and include only one core. See the documentation for core-specific options.

Invoke with:

make -I somedir

Note: installing the fragments in a directory on Gnu Make's include path means you can simply do:

make

See the documentation.

Supported Cores

• avr, 1.8.6
• attiny, 1.5.2
• Arduino esp8266, 3.1.2
• Arduino esp32, 3.3.7
• stm32, 2.6.0
• rp2040, 5.4.4
• Energia tivac, 1.0.4
• Energia msp430, 1.0.7

Note: Energia is no longer developed. Its cores are now integrated with Arduino via this repository.

Dependencies

uC-Makefile requires pcre2grep to be installed.

• elpaso's Makefile for msp430 provided inspiration.
• attiny support is largely due to SpenceKonde's ATTinyCore
