In the world of microcontrollers, the Digital-to-Analog Converter (DAC) is like an artist that can turn cold numbers into vivid analog signals. Today, we will explore how to use the DAC function of STM32 to create a simple and fun noise generator. What is DAC? Why Do We Need It? Imagine you have a pile … Read more
Microcontroller ADC and DAC Applications: Analog Signal Processing Examples Hello everyone, I am the female top laner. Today we will talk about analog signal processing in microcontrollers, focusing on the applications of ADC and DAC. These two modules can be considered important “translators” that connect microcontrollers with the real world. The ADC is responsible for … Read more
Source: https://blog.csdn.net/weixin_48426161 1. Add Header Files First, we need to add the corresponding header files. Since we are going to simulate the serial port, we need to understand the UART communication protocol. The UART communication method consists of 1 start bit, 8 data bits, an optional parity bit, and a stop bit. Therefore, we will … Read more

1 Introduction Recently, I’ve been working on my graduation project. The second board has arrived, and I’ve basically debugged all the components, with a few chips still having test code written for them. One of the chips is the BMP280 barometric sensor, which worked perfectly on the first board, so I can rule out issues … Read more
STM32 I2C EEPROM Read and Write I2C EEPROM is an old friend of microcontroller engineers. Today, we will talk about how to drive I2C EEPROM using the STM32 HAL library, focusing on the common 24C02 chip. But don’t rush, grab a cup of coffee, and let’s take our time. Basic Knowledge of I2C EEPROM EEPROM … Read more
