1. Detection of positive temperature coefficient thermistor (PTC):
When testing, use the multimeter R×1 block, which can be divided into two steps:
1. Normal temperature test (room temperature close t
1) Enable the general purpose input and output port peripheral (GPIO).
2) Configure the corresponding GPIO port as a normal input and output port (select the multiplexing function in I/O multiplexing)

A variable defined as volatile means that the variable may be changed unexpectedly, so the compiler will not make assumptions about the value of the variable. To be precise, the optimizer must careful
Chips are in short supply now, and I need a 3.3V to power an LED. Can I use 5V to connect two diodes in series to reduce the voltage to 3.6V as a replacement?
