Preface Previously, we needed to use CMD to call external tools to send HID commands from the PC to the microcontroller. I want to try integrating this into a DLL and use the call DLL method to achieve it. This would simplify the operation and achieve the goal more quickly. Today, I gathered information from […]

Preface MCSDK has added a custom graphical mode in version 6.3.0, making it relatively convenient. However, in version 6.2.X, you need to manually modify the JSON to add custom functions, which is relatively cumbersome. Additionally, you must first ensure that the MCU pins meet the functional requirements. Here, I’ll provide instructions on how to make

Preface The State Observer Sensorless Algorithm is the method used by ST’s SDK. Here, we will delve into the Observer + PLL algorithm to correspond with the parameters that need to be adjusted in the ST MCSDK, enabling faster and more accurate completion of tasks. The reference material is ST MCSDK version 6.3.0.Among the various

Preface The previous section provided an initial introduction to setting up Ethernet on ST MCUs and pinging the ID. This section will cover two common Ethernet protocols: UDP and TCP. Both server and client configurations will be introduced, and the differences between the two, along with key considerations, will be discussed. The next section will

Preface Ethernet functionality exists in high-spec MCU at ST, but there hasn’t been an opportunity to delve into it thoroughly. This time, a customer raised an issue regarding Ethernet connectivity when not plugged in during boot-up; subsequently, it fails to establish a connection when plugged in later. We intend to seize this opportunity to study

GPDMA GPDMA is a peripheral device on the AHB bus with dual-port masters. It is used to transfer data between external and/or memory through chaining. All programmable transfers by GPDMA provide higher efficiency at the system level, relieving the CPU from performing these data transfer tasks. STM32CubeMX Setting Unlike the old DMA, all settings are

Preface To assist the client, we need to embed the ST update software within the client’s customized software. Therefore, we delve into the original interfaces of STM32CubePrg and gradually integrate them into the client’s specified template. Essentially, the framework is based on STM32CubePrg, with the interface primarily focusing on USB DFU (other customized methods such

Preface Recently, due to a last-minute client request, we need to modify all previously relative path references to absolute paths. Upon investigation, it appears that this can only be accomplished using Windows API for composition. However, our development tools are restricted to using C only, and the use of C++ syntax results in compilation errors.

Preface The current customer requirement involves touching the codebase, requiring assistance in developing 1-wire sensing for the battery, etc. We will go through UART OneWire to verify if it can function properly. There will also be some differences in the next version planning. Here, I’ll integrate and detail the OneWire information for verification methods. Overview

Preface Here, for design reference, a detailed exploration of single-shunt and three-shunt configurations is conducted. This article will delve into the differences between these two configurations and the variances between the old and new versions of MCSDK. It is recommended to use MCSDK 5.x version for verification, as it provides a better UI interface for
