I used the official test. When it was set to return mode, it could run normally. I could receive data on the CAN end using zlg's USBCAN-II. After changing to Normal mode, I could not receive data.I lo...
Weak pull-up: A relatively weak pull-up, generally used in communication with peripheral devices, such as the IIC bus, but cannot be used in pull-up applications that require driving capability. When ...
My computer has 256GB of RAM. I want to expand it to 1GB. It's too far to go to the computer market to install it. I bought a 512GB and a 256GB memory and planned to install it myself, but I can't fin...
My company is designing a product that converts the test force into a digital display, and then controls the entire circuit with a resistor or capacitor sensing button. After obtaining the data, it ca...
Every time I take a car on the highway, I can see the high-voltage power transmission towers on both sides of the highway. The transmission lines on the towers are not of the same thickness. The line ...
