In the previous article, we created different typedef structures. Let’s understand what to do with those typedef structures. Our goal is to configure the peripheral registers of a peripheral.<\/span><\/p>\n

In this case, our peripheral is GPIOD.<\/span><\/p>\n

We also know that we configure a peripheral register using its address.<\/span> <\/span><\/span><\/p>\n

For example, let’s consider the typedef struct which we created for the GPIO_MODE register. <\/span><\/p>\n
