Understanding of CAN bus protocol and porting and using stm32 code
What is CAN bus protocol It is an asynchronous half-duplex communication protocol with only two signal lines, CAN_High and CAN_Low. There are two types of connections: closed-loop bus (high speed) and open-loop bus (long distance) He uses a differential signal to transmit electrical signals The so-called differential signal is the difference in level between two […]

iOS in-app packet capture, NSURLProtocol intercepts network requests within APP
Foreword When developing, you need to obtain data in the SDK. Since you cannot see the code, you can only monitor all network request data and intercept the corresponding return data. This can be achieved through NSURLProtocol, and can also be used to interact with H5. 1. NSURLProtocol intercepts requests 1. Introduction to NSURLProtoco Official […]
