I want to buy a BlackBerry recently, but I don't know much about the mobile phone industry. Can some knowledgeable forum friends please help explain it to me!
I want to buy a brand new genuine product...
I am using the YLP2440 development board. I checked FCLK=200M through CE\windows\cpucheck.exe. I saw MPLLCON=0X5C011 in the BSP, and the calculated FCLK=400. What is the FCLK of this board? If I need ...
The internal instruction cycle of DSP is high, and the main frequency of external crystal oscillator is not enough, so most DSP chips have PLL. But each series is different. 1) TMS320C2000 series: TMS...
I was tired of writing software today, so I took a break and sorted out the software block diagram of the MSP430 ultra-low power clock. Since the specific IC has not been determined yet, I can only wr...

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]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[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]
5. Identifiers and keywords of C language
A complete PIC microcontroller C language program usually consists of six parts: include files (i.e. header files 1, variable definitions, variable de...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[Details]
Abstract: In recent years, with the establishment and grid-connected power generation of a large number of solar photovoltaic power stations at home and abroad, photovoltaic grid-connected inverter...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
The capacity of a battery depends on the amount of charge and discharge, in addition to some factors of the battery itself. Obviously, if the charge and discharge of the battery can be recorded all...[Details]
The automotive power electronics market has grown rapidly as comfort and active safety features become more common. As traditional mechanical functions shift to electronic applications, the demand ...[Details]
