Part 2: STM32 GPIO Features & Configuration Registers. Push-Pull, Open Drain. , Pull-up & Pull-down

In this part of the series, we'll talk about various available STM32 GPIO features and the related registers. We will also discuss about Push-Pull & Open Drain configuration, Pull-up and Pull-down and when to use those. In the end, we will extend our last program of blinking LED and configure an input pin where the onboard push button is connected. We will write the logic to turn-on the LED when the Push Button is pressed and turn it it off when the button is released ! After this you should be able to experiment different GPIO configuration and write logic including Inputs and outputs. In the next part, we will explore another peripheral of the STM32.
