canoe can be used to simulate ECU sending messages. I would like to ask you, how to implement multiple reporting of fault codes (DTC) using CAPL language?...
I would like to ask you how to display DHT11 data on OLED. My idea is to convert the temperature and humidity data collected by DHT11 into string output through the sprintf() function, and then displa...
The question is very simple. Given a variable a, and assigning it an 8-bit value b, you are required to reverse the order of a first (for example, 12345678 becomes 87654321) and then assign it to b. H...
