So im trying to setup some interrupts on the Arduino BLE 33 board, and im looking at Nordics header files for their nrfx drivers.
There is a file called nrfx_glue.h which i’ve attached that creates a bunch of macros but the macros dont do anything.
So im wondering what exactly theyre doing,
here is an example of some of the macros:
/**
* @brief Macro for setting the priority of a specific IRQ.
*
* @param irq_number IRQ number.
* @param priority Priority to be set.
*/
#define NRFX_IRQ_PRIORITY_SET(irq_number, priority)
/**
* @brief Macro for enabling a specific IRQ.
*
* @param irq_number IRQ number.
#define NRFX_IRQ_ENABLE(irq_number)
/**
* @brief Macro for checking if a specific IRQ is enabled.
*
* @param irq_number IRQ number.
*
* @retval true If the IRQ is enabled.
* @retval false Otherwise.
*/
#define NRFX_IRQ_IS_ENABLED(irq_number)
ive tried searching around in the directories and i cant find anything, or on the internet. Just seems weird to make a macro that doesnt do anything unless theyre redefining it?
Heres the header file on github:
https://github.com/NordicSemiconductor/nrfx/blob/master/templates/nrfx_glue.h
>Solution :
It’s a template file according to its comment in the file.
You can find a real implementation for example at https://github.com/nrfconnect/sdk-zephyr/blob/main/modules/hal_nordic/nrfx/nrfx_glue.h.
