Hey everyone, I know this post has been done a lot of times, but people solve it by adding the .c files after including the header file in the corresponding file. The thing is, I've already done this. I just got the STM32 Nucleo with the VL6180 Expansion Board (academic purposes), and I'm trying to communicate with it via UART. I keep getting this error:

Those "undefined symbols" are defined on the bold files, and are being compiled. Did I add them incorrectly of something? I'm using Keil uVision 5. (I added the source files by adding them to the file tree on the left. Screenshot of the tree -> i66.tinypic.com/a5j38p.jpg What am I doing wrong?
Thanks for the help, Alan.
You may also want to look at the following dialog: http://www.keil.com/support/man/docs/uv4/uv4_ca_rtemanager.htm
to see if the peripherals were enabled there, under Device => STM32Cube HAL.
Thanks Zack for the advice, I'll be reading the link you posted to actually know what exactly went wrong in the first place. Hehe thanks again!
