Preface With the increasing demand for low-power products, ST has introduced MCUs and corresponding pins for low-power applications. The L series in ST MCU is a dedicated MCU for low power, and some other MCUs also have low-power pins, such as the F7, H7, G0, G4, and WB series. This chapter will provide a detailed […]

Preface Controller Area Network (CAN or CAN bus) is a feature-rich automotive bus standard designed to allow single-chip devices and instruments on a network to communicate with each other without the need for a host. Based on a message-passing protocol, it was initially adopted in vehicles to reduce the amount of copper wire used by

Preface ADC, or Analog-to-Digital Converter, simply converts analog signals into digital signals. Here are some basic terms related to ADC: ADC conversion modes ADC three mode PS:Note: There are usually positive and negative reference voltages in ADC chips. Positive reference voltage is usually connected to VCC and negative reference voltage is usually connected to GND.

Preface Recently, a customer started researching STM32G031 Flash read and write. When the customer used the sample code provided by the official website to write to Flash and added a Timer interrupt, the system kept entering the HardFault_Handler(). I started researching the Flash status and the HardFault_Handler() checking program. HardFault_Handler Check Procedure First of all,

Preface We want to ensure that the program running before firmware update will not stop, so we need to implement the Dual Bank Flash feature. While downloading the updated firmware on one bank, the program will continue to run on the other bank. After completion, the firmware version will be compared, and the latest version

Preface Since we need to develop a UI interface to control the STM32 and thereby control the sensor, we need to understand the STM32 UART transmission. However, I personally do not like using UART to control components because the transmission is not easy to write, and poor implementation can lead to issues such as data

Catalogue Introduction to SPI Protocol The SPI protocol is a communication protocol (Serial Peripheral Interface) proposed by Motorola. It is a full-duplex communication protocol with high-speed communication on the peripheral device side. It is widely used between communication devices and MCUs, such as ADCs, LCDs, etc. The three lines of the protocol are SCK, MOSI,
