以下是将OpenMV的代码与Arduino Mega 2560实现串口通信的示例代码:
OpenMV的代码中,我们使用Py库将数据通过串口发送给Arduino。Arduino端,我们使用Serial库接收来OpenMV的数据。
OpenMV代码:
```
import sensor
import image
import timeimport pyserial
sensor.reset()
sensor.set_pix(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time=2000)
clock = time.clock()
arduino = pyserial.Serial('/dev/ttyACM0', 9600) # 根据你的串口配置进行修改
while True:
clock.tick()
img = sensor.snapshot().lens_corr(1.8)
# 检测圆形
for c in img.find_circles(threshold=3500, x_margin=10, y_margin=10, r_margin=10, r_min=2, r_max=100, r_step=2):
img.draw_circle(c.x(), c.y(), c.r(), color=(255, 0, 0))
print(c)
img = sensor.snapshot()
# 检测矩形
for r in img.find_rects(threshold=10000):
img.draw_rectangle(r.rect(), color=(255, 0, 0))
for p in r.corners():
img.draw_circle(p[0], p[1], 5, color=(0, 255, 0))
print(r)
# 检测三角形
sum_theta = 0
count = 0
for l in img.find_line_segments(merge_distance=10, max_theta_diff=10):
img.draw_line(l.line(), color=(255, 0, 0))
sum_theta += l.theta()
count += 1
avg_theta = sum_theta / count if count > 0 else 0
if 1 < avg_theta < 110:
print('三角形')
print("FPS %f" % clock.fps())
arduino.write(str(clock.fps()) + '\n') # 发送数据给Arduino
```
Arduino代码:
```cpp
void setup() {
Serial.begin(9600);
}
void loop() {
if (Serial.available()) {
String data = Serial.readStringUntil('\n');
// 在这里插入你想要对接收到的数据进行的处理
// 例如,你可以将数据打印到串口监视器上
Serial.println(data);
}
}
```
请注意,你需要根据你的实际情况修改OpenMV代码中的串口配置和Arduino代码中的处理方式。确保你将OpenMV连接到正确的串口,并根据需要修改波特率和数据处理逻辑。
