Hey guys, I'm new to switching power supplies. I've been reading the TL494 manual for a long time, but I still don't understand how the microcontroller controls the TL494 to generate PWM waves with di...
I'm a newbie. I just started to use AD and encountered some minor problems. The book I bought has some scattered device diagrams and schematics. I want to organize them and make a library, but I can't...
Does SPI have a clock signal as long as it sends data? Now there is data sent out, but there is no clock signal output. I have set it up like this: master mode, SDO controlled by the module, 8-bit tra...
There are two 2407 chips on a board, 5cm apart. If I directly cross-connect the CAN transceiver interface, is it feasible? Do I need 82C50 between them? I have used SPI and SCI, and I want to try CAN....
Regarding the dynamic display of the oscilloscope, to display a 10M bandwidth, no evaluation rate is required, no other processing is required, just sample and display the waveform. So can a crystal o...
1. JTAG port, JTAG pins are defined as follows:MCU TCK - test clock input, connected to the emulator's 7-pinMCU TDI - test data input, connected to the emulator's 2-pinMCU TDO - test data output, conn...
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 LEDs continue to improve in almost every aspect of performance and cost, LED lighting is being used in an increasingly wide range of applications, among which LED street lights are a focus of in...[Details]
1 Introduction
Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]
Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[Details]
My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
1. Background:
The instrument system parameter detection and control of the chemical production workshop of Tangshan Coal Gas Coking Plant are all analog instruments, some of which are eve...[Details]
I. Introduction
Since RS232 has a short communication distance (only 15 meters according to EAT/TAI-232 standard), and can only perform point-to-point communication, it cannot directly f...[Details]
