STM32F4 GPIO Configuration

EOS 5D Mark III-101-2124

Here I will explain how to configure the general purpose input/output ports (GPIO) of the STM32F4xx micro controllers.  Like most other micro controllers the GPIO pins can have multiple configurations and mappings. In this small tutorial, I’ll show the high level functions provided by the GPIO peripheral provided by CooCox.  In another post I will dig in the deeper, low level details by explaining the registers needed for configuring the GPIO ports on the STM32F4xx … Continue reading
