avrdude:tldr:0229d
The command "avrdude -c \?" is used to invoke a utility called "avrdude" that is used to interact with microcontrollers (specifically AVR microcontrollers) for programming and debugging purposes.
Here is a breakdown of the command:
-
"avrdude": This is the name of the utility program that is being executed. It stands for "AVR Downloader/UploaDEr" and is commonly used to program and configure AVR microcontrollers.
-
"-c": This flag specifies the type of programmer or communication protocol being used with the microcontroller. In this case, the "\?" argument is used as the programmer identifier.
-
"\?": This argument is specific to avrdude and is used to list the available programmers or communication protocols supported by the utility. When used in the command line, it will display a list of programmer types that can be used with the avrdude program.
So, if you run the command "avrdude -c \?", it will provide you with a list of programmer types that can be used with avrdude.
