unsetunsetIntroductionunsetunset Last week, I encountered a real project failure where Old Zhang’s robotic arm suddenly started dancing, and the PLC data could not be transmitted to the cloud. Today, let’s discuss how to use a $20 ESP32 module to handle both PLC’s RS485 communication and cloud data integration. No need for high-end gateways; follow me … Read more
Click the above blue text to follow us In Linux systems, Memory-Mapped I/O is an advanced I/O mechanism designed to provide direct access to files by mapping them into the process’s address space. Through this method, data can be accessed directly via memory without the need for system calls to transfer data, thereby improving file … Read more
1. Development Experience The BSP engineers from device manufacturers mainly focus on root filesystem/driver porting/system integration/hardware debugging. It is important to note the distinction from the driver engineers at chip manufacturers. After graduation, the opportunities to write drivers from scratch are few and far between; most of the time, drivers are provided by the chip … Read more
Adding Bluetooth Support to Embedded Linux Background A brief introduction to the entire Bluetooth framework in Linux was provided earlier: Today, we will briefly discuss how to add Bluetooth support in Embedded Linux. Kernel Part The kernel part is mainly divided into two sections: module drivers and the in-kernel Bluetooth protocol stack. Here, we take … Read more
