Dear experts: I am a newbie. Recently, I used a single-chip microcomputer to do an experiment on PWM DC motor speed regulation. I used the incremental PID control algorithm. I have a question that I d...
I just sorted out some things and sorted them out. I found a lot of direct-insert resistors, which are useless and a pity to throw away. Let me see if there is anything I need in the forum. Generally ...
I used two channels of max232 to connect the microcontroller and PC, but the two serial ports cannot be used at the same time, otherwise both serial ports will have garbled characters. However, if I c...
The chip itself has a temperature sensor, and data is collected through the 16th channel of ADC.The routine first creates a project and then imports all files of the routine USER into the USER directo...
