I am currently using PIC18F67J11. I want to know what the highest frequency that this microcontroller can output when the pins are flipped at the highest frequency. I am currently using an internal 8M...
I want to write a keyboard driver. First, I define a global variable "volatile UINT32 g_keyIntIrq" in src/common/intr.c to record the pin where the interrupt occurs. How can I use this variable in my ...
This week I started to learn how to port and use uCOS-II. I have a LM3S9B95 board that I made myself. I downloaded a LM3S9B92 example from the official website, and compared the code while reading Ren...
AD9680 is a dual 14-bit 1GSPS ADC converter. This device has an on-chip buffer and a sample-and-hold circuit. Its low power consumption and small package design bring great convenience to the applicat...
I have a question: I have a board, but when I use RETAILMSG(), DNW does not print out any information (it is already connected to the computer). There are only a few lines of code when it starts, and ...
The following are the steps to build a project based on the TMS320F28035 of the DSPc2000 series using CSS6.0. These are relatively standardized project construction steps. If you need to use DSP to bu...
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[Details]
At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
1 Introduction to LED
With the development of science and technology, people have higher and higher requirements on automobile light sources. LED (Light Emitting Diode) has gradually attracted...[Details]
Car lights, whether headlights, fog lights or tail lights, play an important role in driving safety. However, the material of the car lights determines that the probability of damage in a collision...[Details]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
1. Tips for charging UPS for the first time
After purchasing a new UPS, plug the UPS into the 220V mains power grid and charge it for at least 12 hours to ensure that the battery is fully char...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
Some people think: as long as the program runs well, it doesn't matter how the original program is written. But this is absolutely not the case. Software is not completed in one go, and it is neces...[Details]
Traditionally, when using PLC to control stepper motors, a dedicated stepper motor control intelligent module is usually added to the PLC, and then connected to the drive power supply to realize th...[Details]
In some motion control systems with simple control or low cost requirements, stepper motors are often used as actuators. The biggest advantage of stepper motors in such applications is that they ca...[Details]
LED (Light-emitting diode) is widely used in indication, display and other fields due to its advantages such as long life and low energy consumption. Reliability, stability and high light output ar...[Details]
The Challenge:
Protect historical relics by monitoring environmental factors without affecting their original appearance.
The Solution:
Developed a monitoring system for the...[Details]
