Abstract: Siemens Digital Industries Software deepens its collaboration with Arm, integrating Arm’s Zena CSS into its PAVE360 software to accelerate the development of Software Defined Vehicles (SDVs).At the Siemens Realize LIVE 2025 conference held last week in Detroit, Siemens Digital Industries Software announced the enhancement of its partnership with Arm, integrating Arm’s Zena Compute Subsystem … Read more
As is well known, embedded software development has many environmental dependencies, including dependencies at the software level: 1. Dependency on hardware2. Dependency on compilers3. Dependency on operating systems, and dependencies on system platforms:1. Dependency on the input requirements of the actual project2. Dependency on portability3. Dependency on maintainability (the code needs to be maintainable)4. Dependency … Read more

1. Overview of the File System The MicroPython on ESP32 uses the FAT file system by default, stored in internal flash memory or on an external SD card. The main operations include file reading and writing, directory management, and retrieving file information. 2. Common APIs <span>os.listdir()</span>: List directory contents <span>os.mkdir(path)</span>: Create a directory <span>os.rmdir(path)</span>: Remove … Read more
1. Code The web server based on the ESP32 IDF framework includes WiFi connection, HTTP service, front-end interaction, and hardware control functions: #include <stdio.h> #include <string.h> #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "esp_system.h" #include "esp_wifi.h" #include "esp_event.h" #include "esp_log.h" #include "nvs_flash.h" #include "esp_http_server.h" #include "driver/gpio.h" #include "cJSON.h" // WiFi configuration #define WIFI_SSID "your_SSID" #define WIFI_PASS "your_PASSWORD" … Read more
1. Key Points of UART Hardware Resources and Configuration UART Resources of ESP32ESP32 supports 3 UART controllers (UART0, UART1, UART2), but actual availability is limited by pin conflicts: UART0: Default for REPL debugging (flashing and serial monitoring), using GPIO1 (TX), GPIO3 (RX) UART1: Some development boards connect to external Flash/SD cards (conflicts should be avoided), … Read more

A high-performance chip that injects strong power into your smart devices, leading to infinite possibilities for the future. In today’s global wave of the Internet of Things (IoT), every device yearns for a smart “brain” and efficient “communication capabilities.” Espressif Technology, as a leader in wireless communication and artificial intelligence IoT processor chips, is bringing … Read more
Recently, a colleague raised the following question:“I have a lot of code in my task; does this mean that the stack for this task needs to be allocated larger?”Below, we will describe the relationship between the amount of task code and stack allocation. 1RTOS Task Stack Allocation Many RTOSs on the market require the stack … Read more
Arm has recently disclosed its product brand restructuring strategy, planning to provide self-developed chips to customers, while also mentioning its reliance on the Chinese market and the competitive risks posed by RISC-V.ARM has suddenly announced the abandonment of the Cortex brand, which it has used for twenty years. This once-arrogant British chip giant may indeed … Read more
