install win avr: https://sourceforge.net/projects/winavr/
open a terminal window: ⊞ Win + C M D
put these files in a folder “path/to/folder/c-blink”, and run: \
cd path/to/folder/c-blink make make flash
The important bit is you Makefile. Depending on your configuration you might have to adjust the name of the USB-port your Arduino is connected to:
AVRDUDE = avrdude -q -V -p atmega328p -C C:\WinAVR-20100110\bin\avrdude.conf -D -c arduino -b 115200 -P COM6
For Mac install crosspack-avr:
https://www.obdev.at/products/crosspack/index.html
For Linux install avrgcc toolchain:
sudo apt install avrdude gcc-avr avr-libc make
open terminal/bash:
Mac: cmd-space and then type terminal
Linux: usually Ctrl+Alt+T
put the files (download below) in a folder path/to/folder/c-blink
open the Makefile with a text editor and edit the following line:
AVRDUDE = avrdude -q -V -p atmega328p -C /usr/local/CrossPack-AVR/etc/avrdude.conf -D -c arduino -b 115200 -P /dev/cu.usbmodem14101
changing:
/dev/cu.usbmodem14101
with the serial port where the Arduino is connected to, you can get it from the Arduino IDE Tools→Port, or via bash with
ll /dev/ | grep cu.usbmodem /usr/local/CrossPack-AVR/etc/avrdude.conf
with the folder where you have installed the AVR Crosspack/Toolchain, if different
save the Makefile and then run:
cd path/to/folder/c-blink make clean make make flash
