I want at91rm9200 to boot from flash. I see the partition table. I need to burn boot.bin, u-boot.gz, uImage, and finally the u-boot environment variables. Where can I find the boot.bin and environment...
Last week we sent out a 32G USB flash drive in an event. People also shared their comparison of the transmission speed of this USB flash drive on the forum. Some people questioned that USB only relies...
The course design requires counting two external pulse signals separately. Please send me a counting program for a 430 microcontroller, but not a frequency counter. . ....
I suddenly had the urge to do a series of topics on sound visualization. This topic is a bit difficult and covers a wide range of areas. The related FFT and FHT algorithms are also quite complicated, ...
Trash cans are getting more and more advanced. Look at this one. It has the function of freezing. It is like putting the trash in a refrigerator. The odor is frozen.This is just like a small refrigera...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();

As cellular phones become more advanced, the power consumption of the system during operation and the power consumption during standby are also increasing. Therefore, the power management design of...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[Details]
Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
Among the many members of the single-chip microcomputer family, the MCS-51 series of single-chip microcomputers has occupied the main market of industrial measurement and control and automation eng...[Details]
