I designed a 4-key keypad using C51 programming. I want the program to determine whether the key is double-clicked or long-pressed. In the double-click recognition part, I want to set the interval bet...
This part is quite boring and requires patience. If you make a mistake in entering a command, the result may be incorrect. Then follow the above article [Altera SoC Experience Tour] + Lark ARM develop...
Recently, I was debugging a circuit that uses a transistor (NPN) to achieve high and low level reversal. As shown in the figure, I found a strange failure problem: after a short period of operation, w...
The circuit diagram is shown in Figure 1, and Figure 2 is the waveform on the sampling resistor R detected by a differential probe. The problem is as follows:
1. Which of the following methods is used...
I was debugging a program recently and wanted to see the waveforms of some variables. Since I don't have an oscilloscope, I could only use the Cube Suite+ simulator function to simulate the operation ...
EtherCAT (Ethernet for Control Automation Technology) is a real-time industrial fieldbus communication protocol based on an Ethernet-based development framework. EtherCAT is one of the fastest indu...[Details]
