We use ADC2 to implement the potentiometer knob. Potentiometer Knob Initialization Code.c void PotentiometerKnob_Init(void){ /* Enable clock */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC2, ENABLE); // Enable ADC2 clock RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE); // Enable GPIOA clock /* Set ADC clock */ RCC_ADCCLKConfig(RCC_PCLK2_Div6); // Select clock division 6, ADCCLK = 72MHz / 6 = 12MHz /* GPIO initialization */ GPIO_InitTypeDef GPIO_InitStructure; GPIO_InitStructure.GPIO_Mode … Read more
Next, I will present embedded practical projects in the form of sensors + projects. Today, we will learn about the first article in the embedded sensor series – a comprehensive guide to using the GY-906 non-contact infrared temperature sensor. In the world of embedded development, sensors act like “eyes” and “ears” that allow devices to … Read more
Introduction In the past, when developing with STM32, communication with mobile phones generally required an additional Wi-Fi module or Bluetooth module, typically connected via serial port to the Bluetooth module. When designing wireless communication solutions, the ESP32 is often chosen, as this Bluetooth + MCU integrated solution is very appealing. However, the ESP32 has its … Read more
Click the blue text Follow us 1. Introduction to W25Q64 The W25Q64 (64Mbit) is a serial FLASH memory solution designed to provide minimal space, pin count, and power consumption for systems. The 25Q series offers greater flexibility and superior performance compared to standard serial FLASH memory. Based on double/quad SPI, they can immediately provide data … Read more
For other basic configurations, refer to my article: STM32F103C8T6 Microcontroller CUBEIDE Integrated Development Environment Configuration Process.Based on the above, follow these steps:1. First, select sys->Timebase source and choose TIMx. This article selects TIM1 (it is best to choose this; others only have basic functions like TIM2, TIM3, and TIM4. TIM1 is an advanced timer, and … Read more
The time-slice polling method is often mentioned alongside operating systems, meaning it is frequently used in operating systems:RTOS in STM32 microcontroller development. The following will reference others’ code to demonstrate how to establish a time-slice polling architecture program.Timer Reuse Executing other functions while one function is delayed makes full use of CPU time, doesn’t it … Read more
Introduction to STM32 Key Handling: From Basics to Complete Implementation (with Code Examples) 🔑 What is a “Key”? In embedded development, keys (Button/Key) are one of the most common forms of human-machine interaction. It is essentially a mechanical switch: Based on the above schematic analysis, we can conclude: • Not Pressed: The circuit is open, … Read more
