In a previous thread Clawson says
how to use a single "usart_routines.c" with several different projects.
the "trick" is that when you "add existing" to add the UART_routines.c to your new project you will note that the [Add] button has a drop arrow to the right. Select that and you will see there is a second add option that is "Add as link". This makes the .c file visible to your project but does NOT copy it from the original location. So you keep just one master copy on your drive and all your projects "link" to it.
When I go to add a file to a project, I right click on the project and when I hover over Add I have the choices of adding a New Item, and Existing Item, or a Folder. I don't get the option to add as a link. Am I doing something wrong?
And lets say I do get to add a file as a link. If I modify the file in my project with it modify the master copy so it gets changed everywhere?
I am making my own libraries, but having all the files I use in one place and adding them as a link sounds useful.
thanks for your help.
