Hello, I'm currently programmed a STM32F4 Discovery with the IDE Atollic. In my program, I get two fonction, the first in the file ''stm32f4xx_it.c'' and the second in the file main.c and i want to known if i can transmit a variable betwen the two fonctions.

Sorry for my bad English !!Thanks,

This isn't an Atollic issue, simply a C one.

Define a global variable in one of the files, and refer to it with the ''extern'' keyword in the others. For variables you change in an interrupt consider also the ''volatile'' keyword.
