我目前正在使用.net微框架在Netduino Plus 2上做一个项目,这需要我为脉冲传感器编码。我试过找到脉冲传感器的代码,但无济于事。我尝试将AnalogInput代码用于脉冲传感器,但输出值似乎不对(尽管传感器附近没有心跳,但仍有一个恒定的高值)。请指教!
以下是我目前的心跳传感器代码:
using System;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
namespace heartrate
{
public class Program
{
public static void Main()
{
SecretLabs.NETMF.Hardware.AnalogInput rate =
new SecretLabs.NETMF.Hardware.AnalogInput(Pins.GPIO_PIN_A0);
int sensorvalue = 0;
while (true)
{
sensorvalue = rate.Read();
Debug.Print("" + sensorvalue);
Thread.Sleep(1000);
}
}
}
}
以下是传感器的规格,传感器的外观以及连接方式。 http://www.elecrow.com/wiki/index.php?title=Pulse_Sensor (本教程适用于arduino,但我认为接线类似于Netduino)

很难说没有关于脉冲设备及其连接方式的规格。对于模拟输入和在我的最新项目(https://github.com/osstekz/cncBuddy)中的输出我使用类InputPort& OutputPort(Microsoft.SPOT.Hardware) 例如:
public NESControllerAdapter(Cpu.Pin pinClk, Cpu.Pin pinLatch, Cpu.Pin pinData1/*, Cpu.Pin pinData2 = Cpu.Pin.GPIO_NONE*/) {
// Binds to all pins
this._outpClk = new OutputPort(pinClk, false);
this._outpLatch = new OutputPort(pinLatch, false);
this._inpData1 = new InputPort(pinData1, false, Port.ResistorMode.Disabled);
//if (pinData2 != Cpu.Pin.GPIO_NONE) this._inpData2 = new InputPort(pinData2, false, Port.ResistorMode.Disabled);
}
...然后就像你的rate.Read();环
public int ButtonPressed() {
// Locks all parms
this._PinTick(this._outpLatch);
// Reads plug state value
for (int i = 0; i < CncBuddyShared.iTOTALNESCONTROLLERBUTTONS; ++i) {
// Read the value, if true return this index as the first pressed button
if (this._inpData1.Read() == false) return i;
// Selects the next value
this._PinTick(this._outpClk);
}
return NESCONTROLLER_PRESSEDBUTTOM_NONE;
}
