Introduction In the previous article, we briefly introduced the difference between bare-metal drivers and device drivers, as well as the driver architecture of character devices in the Linux kernel. Without an operating system, upper-layer applications directly access the driver interface, and application engineers need to know the driver interface for each device. When accessing Flash, … Read more
Introduction Today’s content does not involve the Zigbee protocol, but rather the use of the CC2530 microcontroller to control an LED with a button. This tutorial is divided into two parts: Polling to detect button levels for controlling the LED. Using button interrupts to control the LED. 1. Principle Analysis 1. Button Functionality The schematic … Read more
Introduction From this article, we officially step into the Zigbee protocol. This article will start with the basic Zigbee protocol, without using any packaged protocol stack. The content is migrated from a basic protocol template to the project, and has been updated to the code repository. Repository address: https://gitee.com/jeady5/zigbee-emaple Based on today’s project, I will … Read more
According to the IHS 2016 Touch Sensing Technology and Market Report analysis, the on-cell touch solution not only advances the display market towards flexible products but is also a fundamental technology for Y-OCTA touch control. Smartphone OLED panel manufacturers, especially Samsung Display, are continuously working to integrate touch screen structures into displays to achieve film … Read more
The market is seeing an increasing number of smartphones with OLED screens, especially since the iPhone X adopted Samsung’s AMOLED (a branch of OLED). It seems that if flagship phones do not use OLED, they are not considered true flagships. Previously, only Samsung had mass-produced OLED screens for smartphones (Xiaomi NOTE2 used LG’s OLED, which … Read more

LIN is a subnet of the CAN bus system, also known as a “local subsystem.” Data exchange between all systems controlled by the LIN bus in automobiles must be achieved through the CAN bus control unit. As a beneficial supplement to the CAN bus, the LIN bus can complete vehicle functions more economically and effectively. … Read more
In assembly language, there are specific instructions to output high or low levels on a certain port. Taking port P1.0 as an example: The instruction to set this port to high is: SETB P1.0 The instruction to set this port to low is: CLR P1.0 Now, we will connect a small light to the microcontroller’s … Read more
