STM32F103 Clock Setup using Registers
This tutorial will cover Clock setup, Timer Setup for Delay, and GPIO configuration for STM32 F103 using the Register based programming.
STM32 GPIO INPUT Configuration
This tutorial will cover how to configure the GPIO pin as input in STM32, and then how to read it’s state whether it’s high or low
STM32 GPIO OUTPUT Config using REGISTERS
To configure the pin as output, we will modify the GPIOx_MODER Register… configuring different modes for the GPIO in STM32
