直接复制就行，代码简洁，PA4和PA6引脚输出SPWM脉冲，PA4输出时，PA6关，PA6输出时PA4关

const int sPWMArray[] = {124,464,245,349,359,244,463,153,552,80,630,29,1880,29,630,80,552,153,463,244,359,349,245,464,124,586};
const int sPWMArrayValues = 26;
const int sPWMpin1 = PA6;
const int sPWMpin2 = PA4;
bool sPWMpin1Status = true;
bool sPWMpin2Status = true;
void setup() {
pinMode(sPWMpin1, OUTPUT);
pinMode(sPWMpin2, OUTPUT);
}
void loop() {
for(int i(0); i != sPWMArrayValues; i++)
{
if(sPWMpin1Status)
{
digitalWrite(sPWMpin1, HIGH);
delayMicroseconds(sPWMArray);
sPWMpin1Status = false;
}
else
{
digitalWrite(sPWMpin1, LOW);
delayMicroseconds(sPWMArray);
sPWMpin1Status = true;
}
}
// Loop for pin 2
for(int i(0); i != sPWMArrayValues; i++)
{
if(sPWMpin2Status)
{
digitalWrite(sPWMpin2, HIGH);
delayMicroseconds(sPWMArray);
sPWMpin2Status = false;
}
else
{
digitalWrite(sPWMpin2, LOW);
delayMicroseconds(sPWMArray);
sPWMpin2Status = true;
}
}
}
