I recently watched a movie about Wolverine, and I want to use MSP430FR5969 and a solar cell to make a thermometer that can display the temperature value on an LCD screen. Note that the solar cell here...
The board I use is the ARM920T-based development kit FDAC9200DevKit-Ⅱ (from Shanghai Fuxu Information Technology Co., Ltd.), which is several years old. The flash is two SST 39VF3201 (4M), with the st...
Checking the timer capture time of G2, I found in the data sheet that the minimum is 20ns, but the maximum clock of the timer is 16MHz, which is equivalent to 62.5ns. I uploaded a screenshot of the ma...
I wrote a driver myself, the code is as follows: BOOL WINAPI DllEntryPoint(HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved) { switch(ul_reason_for_call) { case DLL_PROCESS_ATTACH: DEBUGMSG...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
Do you often have to add brake fluid to your car's brakes? The fact that you need to pump out the brake fluid to make sure there is no gas in the brake fluid line may not be done by the car owner h...[Details]
For a long time, due to the limitation of hardware conditions, the display devices of traditional small handheld devices such as PDA are usually monochrome LCD, and the user interface is very simpl...[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]
With the development and widespread application of computer technology, especially in the field of industrial control, computer communication is particularly important. Although serial communication g...[Details]
