Preface The customer is using the STM32G491MCT6 part number, but during the trial production phase, some components are getting stuck while reading Flash. This issue hasn’t been encountered in regular testing, so we had to rely on experience to troubleshoot. Using PC counter, we eventually discovered that the reported positions were all in the NMI […]

Preface There are many options when it comes to choosing an LCD, with various sizes available. However, if you need to display colorful images, we recommend the ST7735 display. It offers excellent value for money and delivers good performance. This example will introduce the usage of the 1.8-inch ST7735 color display screen with STM32 microcontrollers.

Preface Here, in the development of USB DFU, examples typically involve using external pins for switching. However, in practice, commands are issued via USB or other interfaces to switch between the APP or Bootloader mode. Using Flash as a flag is limited to 10,000 usage cycles. In this case, SRAM can be employed as an

Preface The purpose of ‘attribute__’ is to store variables or arrays at a specified address. In practical applications, program version information is usually fixed at a specific flash address. Here, I needed to assist in modifying the Hex burning file to recognize version information. However, after attempting to use STM32CubeIDE, I found it didn’t work,

Preface The customer used MCSDK 5.4.8 to generate code for a Hall sensor, but when the motor had a load during startup, there was a magnetic excitation noise. However, there were no additions to the code, only a motor stop and restart. We used the DAC interface for easy debugging and ultimately identified algorithmic adjustments

Preface This section will address common issues encountered with MCSDK and provide explanations and adjustments. Relevant information locations will also be organized to facilitate a quicker start for everyone in motor control. MCSDK Program Main Structure After generating code using MCSDK, the main program section and mathematical equations are as shown in the following figure:

Preface The customer requires encryption protection for certain devices. ST offers two options: Directory Structure of V4 vs. Directory Structure of V3 The directory structure of the V3 software package corresponds to a separate directory for each STM32 series. The directory structure of V4 is fully compatible with the Cube/X-Cube software package (STM32CubeXX / X-Cube-XXX)
