After modifying the driver of the touch screen controlled by at91sam9261+ADS7843e under Linux, I use a small test program to read the coordinates of the touch screen, but the coordinate values read ou...
Network design: Building a complete ZigBee mesh network includes two steps: network initialization and node (router or terminal) joining the network. The node joining the network also includes two ste...
This article introduces a miniature home electrocardiograph. This system uses a low-power 16-bit single-chip microcomputer MSP430 F135 as the control core of the whole system, and is equipped with a c...
I only know VC. I want to learn file-driven development, network-driven development. In short, it is software-based driver development. What books should I read? Are there any good books that must be ...
introduction
In the discharge process of tokamak plasma physics, the study of rupture and sawtooth is of great significance. Rupture and sawtooth exist in most tokamaks. Rupture is a notew...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
