There's a mix of standards, some variables have upper case, underscore and camel case. Typically the standard is:
Functions & local variables: all lower case and separated by "_"
Classes: Camel case
Global Variables: Upper case and separated by "_"

[M0stafaRady]

Functions & local variables: all lower case and separated by "_"

The standard used here is <interfacename>_<function named Camel case >

[marwaneltoukhy]

For example here it's a mix of "_" and camel case

[marwaneltoukhy]

Functions & local variables: all lower case and separated by "_"

The standard used here is _

It's okay to comeup with a standard for your code, but it's important to keep it consistent, for example; if the iterfacename is going to be all caps, it should be consistently all caps. More examples:
IRQ_getFlag, the interface is all caps, but in GPIOs_readHigh it is not, and LogicAnalyzer_inputEnable is camel case.
Also, are you using the whole interface name or the acronym? looks like your using acronyms in all the function names except with LA.
