我无法让布尔值上班,我不知道自己在做什么错。谁能看一下代码并给我提示一下它有什么问题吗?我测试了不同的编写方式,但没有成功。布尔值唯一起作用的时间是我将代码置于void循环之下。但是我不能在那里使用它。
#include <RemoteReceiver.h>
boolean statusLed1 = false;
void setup() {
Serial.begin(115200);
// Initialize receiver on interrupt 0 (= digital pin 2), calls the callback "showCode"
// after 3 identical codes have been received in a row. (thus, keep the button pressed
// for a moment)
//
// See the interrupt-parameter of attachInterrupt for possible values (and pins)
// to connect the receiver.
RemoteReceiver::init(0, 3, showCode);
}
void loop() {
}
// Callback function is called only when a valid code is received.
void showCode(unsigned long receivedCode, unsigned int period) {
// Note: interrupts are disabled. You can re-enable them if needed.
// Print the received code.
Serial.print("Code: ");
Serial.print(receivedCode);
Serial.print(", period duration: ");
Serial.print(period);
Serial.println("us.");
if (receivedCode == 353805)
{
statusLed1 = true;
}
if (receivedCode == 352829)
{
statusLed1 = false;
}
if (statusLed1 = true) {
Serial.print("on");
}
if (statusLed1 = false){
Serial.print("off");
}
}
最佳答案
if (statusLed1 = true) {
书中最古老的陷阱。
=
是分配,==
是相等比较。另外,无论如何不要与这样的布尔值进行比较。
if (statusLed1) {
