In actual high-speed signal processing, in order to increase the sampling rate (but at the same time limited by the chip), two AD chips are needed to perform odd and even sampling and splice them into...
This board is a simplified version of BBB. Compared with the full version, it lacks eMMC, HDMI, USB and other components! The schematic diagram is the same as the full version! It was originally used ...
I have just come into contact with TM4C123GH6PM, and now I want to learn how to read and write SD cards using the SPI interface. If anyone has relevant information, please leave a message. Thank you!!...
This book is a theoretical introduction monograph that discusses from 51 to ARM--32-bit embedded systems. The content mainly involves the basic knowledge of 51 series microcontrollers, the basic knowl...
The fault is: there is voltage when the machine is turned on. Disconnect all loads. Connect a dummy load and the same thing happens. Even if the trigger end of the thyristor is disconnected, there is ...
The MSP430 microcontroller is an ultra-low power microprocessor that TI has launched in 1996. It also integrates many module functions, so that one MSP430 chip can complete the functions that can only...
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]

0Introduction
In oil drilling, accurate measurement of wellbore posture is the premise of wellbore trajectory control. To this end, this paper fully combines the advantages of single-chip ...[Details]
As microcontrollers become less expensive and more powerful, electrical designers are finding it more cost-effective to use multiple small controllers in both single-board and multi-board systems. ...[Details]
Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[Details]
The overcurrent and overheating coordinated protection technology implemented by polymer positive temperature coefficient devices (PPTC) can protect motors, controllers and electronic components in...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]

need to be small, thin, durable, reliable, and have a long standby time. Therefore, system desi...[Details]
Preface
For a long time, SD cards with Flash Memory as storage have been widely used in consumer electronic products due to their small size, low power consumption, erasable and non-volati...[Details]
Fetal monitoring is an important means to ensure the safety of perinatal mothers and fetuses and achieve eugenics. Intelligent fetal monitoring is a monitoring method that analyzes the health stat...[Details]
1 Introduction
The high temperature tester is mainly used for temperature tracking measurement and data acquisition during the heating process. By systematically analyzing the test data,...[Details]
1 Introduction
Intelligent software agents are software programs that can perform specific tasks for users, have a certain degree of intelligence, can autonomously perform some tasks, and ...[Details]
The microwave multifunctional therapeutic device uses microwave radiation for heating treatment, which can achieve the effects of sterilization and blood circulation. Using microwaves to directly c...[Details]
