#旭日X3派首百尝鲜# 【AI健身实体机】Arduino使用MAX30102人体心率血氧检测模块在X3派上位机上的显示
一、arduino与旭日x3派通信
1.查看x3派上python是否安装serial包
2.x3派与arduino之间通过usb进行通信
3.在终端上输入 ls /dev/tty* 出现acm0说明两者可以正常通信
4.在arduino上烧录代码
void setup() { serial.begin(9600);}void loop(){ if ( serial.available()) { if('s' == serial.read()) serial.println(helloworld!); }}
5.在x3派上测试是否能够收到信息
在终端下通过python3进行测试
最后print可以出现helloworld！
import serialser=serial.serial('/dev/ttyacm0',9600,timeout=1)while 1: ser.write('s'.encode()) msg=ser.readall() print(msg)
ser.write('s')会报编码的错误，使用方法encode()解决。
6.权限不够，退出后终端输入sudo su进入管理员模式可以解决
二、max30102人体心率血氧检测模块在上位机旭日x3派上的数据显示
1.max30102
max30102是一种用于可穿戴健康设备的高灵敏度脉搏血氧仪和心率传感器。
max30102内部集成了一整套完整信号采集电路，包括光信号发射及接收、ad转换、环境光干扰消除及数字滤波部分，只将数字接口留给用户。

3.接线
vcc----5v
gnd---gnd
scl----a5
sda---a4
将max30102周围用绝缘黑胶布包裹起来，避免手碰到电阻对结果产生影响
4.x3派代码
sudo nano max30102_test.py
import serialser=serial.serial('/dev/ttyacm0',115200,timeout=1)while 1: msg=ser.read(10) print(msg)
5.运行代码
python3 max30102_test.py
将手放上测量心率血氧，心率可以较快得出，血氧需要等待较久。
hr为心率，spo2为血氧，ir和red为计算的中间值。
