volatile is equivalent to telling the compiler that the things declared by it are changeable and uncertain, and may be changed by external programs (such as interrupt programs), and prohibiting the co...
As shown in the picture, the simulation is good, giving a 0-5V sine wave, but after the actual board is powered on, the first op amp becomes hot and the power is also very high. What is the problem?...
When debugging a system recently, I found that 430f149 could not communicate with MCU51. The data intercepted by interrupt mode showed that 430F149 only received the first few bytes of data sent by MC...
