Interrupts are a major feature of the MSP430 microprocessor. Effective use of interrupts can simplify programs and improve execution efficiency.
MS430 has many interrupts, and almost every peripheral
When debugging the 5509A program, I found that I could not connect to the emulator, but I could do it by changing the board. It took me a while to solve this problem. I recorded the test process and s

Hello everyone: I used the AD633 multiplier to make an analog phase-detection circuit, multiplying the two sine waves X and Y, and getting the following oscilloscope waveform at the OUT end. The outpu
