The touch screen is summarized as an input subsystem, which is mainly for resistive screens. Its usage process is as follows: When the touch pen is pressed, an interrupt is generated. In the interrupt...
I applied for the above two samples. Only these two are useful to me. If I don't have more, it will be wasted. Among them, TPS25940A is a load switch. And it has a back-to-back MOS tube structure insi...
[table][tr][td]1. Talk to other software developers as much as possible; cultivate personal relationships; talk to people who disagree with you; talk to people who have more experience; talk to people...
Can I use two compilers at the same time in a Makefile? For example: udptalk1:udptalk.c gcc -o udptalk1 udptalk.c udptalk2:udptalk.c arm-linux-gcc -o udptalk2 udptalk.c Can I write it like this? Why c...

Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[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]
Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor.
This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input h...[Details]
This paper establishes a fuel cell engine test platform based on the NI integrated hardware and software environment. This platform can realize the test and control of fuel cell engines and their a...[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]
Microcalorimetry
is used to determine energy relationships. Microcalorimetry techniques are often required when performing calorimetric experiments with small sample sizes or slow heating rat...[Details]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
