# -mmcu: specifies the architecture of the boardĬompile: # compiles the C code to a hex file # -Os: optimizes the code for size (uses optimizations from O2 that don't increase size) PROGRAMMER = arduino # which bootloader to useīAUD = 115200 # speed of communication to the board PORT = /dev/com4 # serial port that the board is connected toĭEVICE = atmega328p # which microcontroller is on the board (usually ATMEGA328P for arduino) #! this will change depending on your system If you were curious, that makefile code is: I know that it's a user error, I just don't know how to correct it.Īnd none of these are the answer. I have an Uno connected to COM4 on my windows laptop, but I'm using (what I believe is) an Ubuntu image hosted on WSL, and no matter what I try I can't seem to get the makefile to see the board. Anyway, compile works just fine, but upload has a problem because I can't for the life of me figure out what to put down for Port. This makefile has some functions, which I will include below, and a list of things above those functions that look a lot like variables to me, though I suppose I might not be the most informed on makefiles. I have the example code (just a simple blink function written in C) and a makefile, which I think I have a grasp on how to use but I could also be wrong. So, I'm working on a project that requires me to be able to upload C code to my arduino without using the arduino IDE (I've been informed that this is called flashing, unless I'm completely mistaken).
