Scan to FollowLearn Embedded Systems Together, learn and grow together One of the main differences between RT-Thread and many other RTOS like FreeRTOS is that it is not just a real-time kernel, but also has a rich set of middleware components, as shown in the figure below. FreeRTOS and RT-Thread are two common embedded real-time … Read more
1. Introduction In discussions with developers using the Xianji RT-Thread BSP, it was found that the SPI device driver occasionally encounters illegal access exceptions in polling mode (as shown in the figure). Problem reproduction scenario:: 1. The developer only needs to transmit a single message once but did not explicitly initialize the struct rt_spi_message’s next … Read more

CANopen is a communication protocol based on CAN that has been widely used in the industrial field. CAN provides reliable low-level data transmission, while CANopen offers a standardized application layer protocol. In the CANopen protocol, each CANopen device has an object dictionary. The CANopen device model is shown in the figure below. The object dictionary … Read more
This article is reprinted from the Jishu Community Author: Once a Job’s Tears Introduction Recently, I had the privilege of experiencing the Lingdong Micro MM32F5265 development board. The MM32F5260 is equipped with the Arm China “Star-MC1 core” processor, which offers high performance and is aimed at high-reliability application fields such as home appliances and industrial … Read more
Recently, RT-Thread engineers completed the BSP adaptation based on the Renesas CPK-RA2L1 development board, supporting drivers for peripherals such as GPIO, UART, I2C, SPI, ADC, DAC, PWM, CAN, on-chip Flash, Watchdog, RTC, etc. With the support of Renesas engineers, the power component (low power LPM) adaptation was completed. Actual measurements show that the chip can … Read more
The Internet of Things (IoT) was still a very vague concept a decade ago. With the development of technology across various industries over the past ten years, and the deepening commercialization of 5G, the mainstream communication infrastructure representing the next decade, the initial slogan of “connecting everything” has gradually become clearer. The competition among IoT … Read more
This article mainly shares an open-source management module that helps achieve layered management of applications and hardware in an MCU project. Nowadays, project requirements are more complex, which naturally imposes stricter demands than before. From a technical perspective, I still recommend that everyone should maintain a layered structure (application and driver) in their projects. This … Read more
