The serial port of 430 should be 3.3V TTL logic level, right?The problem is this, I have another external device A here, which provides TTL interface. When it is suspended, I use an ammeter to measure...
Using J-LINK under KEIL4, I was able to read the ID at first, but after forced burning, I couldn't connect anymore!There is also ARMWSD where you can download it. I searched for a long time but couldn...
Is there no stack security check for the debug compiled by evc4.0? Recently, when debugging, I get an error and cannot locate the error function stack of the program. What methods do you have for debu...
About Reasoning
Husband: You are unreasonable.
Wife: I have never reasoned with you. Home is not a place for reasoning. Besides, you are a man and 8 months older than me, so you have to give in to...
There is a problem with the PS2 keyboard of the system compiled using CE5. It should be that the code is broken. The bios used only supports the first set of scan codes. Can CE5 support the first set?...
Hello everyone. I would like to ask you a question; Regarding the sampling of the stm32AD injection group, we have two methods to obtain the results of AD conversion. Method one is: directly read the ...
No matter which processor you are learning, the first thing you need to understand is the registers and working mode of the processor.
ARM has 37 registers, including 31 general registers and ...[Details]
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[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]

Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[Details]
The principles to be followed are as follows:
