this is the list of important things you should know to protect your interrupts:

functions that use interrupts should disable them before they run. if you are using a library that doesnt, then you should either use its functions or write your own.
functions that do not use interrupts should disable them before they run. it is common practice to have a global variable or function that can set the local variable that controls interrupts to a special value such as (interrupt disabled). you can then use that variable in functions that do not have interrupts to disable the interrupts for those functions as well.
if you have functions that use interrupts, then they should call functions that disable interrupts.
all functions should check their interrupt status before they run.

this is a list of things you have to know before you decide to disable interrupts. it doesnt really need a tutorial, but its important to know some basics in order to protect your interrupts and run your code without any interference from the os.

second, if you disable interrupts, then you have to be careful about all your function calls. if you call any functions with interrupts enabled, then you have to disable them as well. otherwise, you will get an unpredictable result. this can be especially confusing if you call functions that do not save and restore the stack pointer and returns normally. this is what the bsp library does in the cortex-m4 based devices like stm32f4.

finally, one thing to note is that interrupts should not be disabled for any other reason. if you disable interrupts for any reason, then it will cause issues with the software and cause it to be unstable. the best example of this is that the stm32f4 devices come with a debug feature that allows you to disable interrupts by means of an option in the menu. the problem with this is that you need to have the device connected to a pc for this to work, and if you do this, then the interrupts are disabled.
