I have a circuit board with an output of 24V DC and about 3A. Now I want to design a circuit to act as a load for the circuit board. The loads in actual applications are solenoid valves and relays. Ca...
After I compile the program and click on the error prompt, the cursor will normally jump to the error line. However, when I click on the error prompt, a dialog box pops up saying that the path is not ...
Some of you may look down upon this title. Actually, it took me a day to come up with this. Some forum users may ask: Isn't there this routine in the ST library routine? Yes, there is, but that is bas...

How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
