STM32F103 SPL Tutorial 3 – GPIO Read Button

STM32F103 GPIO

In this tutorial, I will explain how to use STM32F103 GPIO for reading a push button. STM32F103 GPIO can be configured in 4 different modes (input mode, output mode, analog input mode, and alternate function mode). For reading a button, we need to configure a GPIO pin in digital input mode.

STM32F103 SPL Tutorial 2 – GPIO Write LED

STM32F103 GPIO

STM32F103 GPIO are generic pins that can be configured as input or output. In this tutorial, I will explain how to use STM32F103 GPIO for controlling an LED on/off. STM32F103 GPIO can be configured in 4 different modes (input mode, output mode, analog input mode, and alternate function mode). For controlling an LED on/off, we need to configure a GPIO pin in output mode.

STM32F103 SPL Tutorial 1 – Create a New Project in Keil uVision IDE

STM32F103

STM32F103 is an STMicroelectronics’s 32-bit microcontroller based on the ARM Cortex-M3 processor. The processor clock speed is up to 72MHz. It has 64 Kbytes of flash memory and 20 Kbytes of SRAM. There are several development boards for this microcontroller available on the market. In this tutorial, I will use this development board. It has 40 pins that fit into breadboard. It has 2× 12-bit ADCs, 7× timers, and Up to 9 communication interfaces (3× USART, 2× I2C, 2× SPI, 1× CAN, 1× USB).
