请在这里粘贴代码 ```# Blob Detection and uart transport import sensor, image, time from pyb import UART import json # For color tracking to work really well you should ideally be in a very, very, # very, controlled enviroment where the lighting is constant... red_threshold=(18, 69, 40, 86, 0, 72) # You may need to tweak the above settings for tracking green things... # Select an area in the Framebuffer to copy the color settings. sensor.reset() # Initialize the camera sensor. sensor.set_pixformat(sensor.RGB565) # use RGB565. sensor.set_framesize(sensor.QQVGA) # use QQVGA for speed. sensor.skip_frames(10) # Let new settings take affect. sensor.set_auto_whitebal(False) # turn this off. clock = time.clock() # Tracks FPS. uart = UART(3, 19200) def find_max(blobs): max_size=0 for blob in blobs: if blob.pixels() > max_size: max_blob=blob max_size = blob.pixels() return max_blob while(True): img = sensor.snapshot() # Take a picture and return the image. blobs = img.find_blobs([red_threshold]) if blobs: max_blob=find_max(blobs) #print('sum :', len(blobs)) img.draw_rectangle(max_blob.rect()) img.draw_cross(max_blob.cx(), max_blob.cy()) output_str="%d%d" % (max_blob.cx(),max_blob.cy()) #方式1 #output_str=json.dumps([max_blob.cx(),max_blob.cy()]) #方式2 print('',output_str) uart.write(output_str+'\r\n') 单片机程序 #include "stm32f10x.h" #include "./led/bsp_led.h" #include "./uart/bsp_uart.h" void delay(uint32_t count) { for(; count!=0; count--); } int main(void) { uint8_t temp; LED_GPIO_Config(); DEBUG_UART_Config(); while(1) { temp = getchar(); printf("%d%d\n",temp); if (temp=(75,73)) {LED1_ON; LED2_OFF;} else if (temp=(75,46)) {LED2_ON; LED1_OFF;} else; {LED2_OFF LED1_OFF;} } 串口助手接收数据如下:[16:46:56.953]收←◆541073821696 511073821696 [16:46:56.988]收←◆541073821696 501073821696 [16:46:57.024]收←◆541073821696 501073821696 [16:46:57.059]收←◆541073821696 501073821696 [16:46:57.094]收←◆541073821696 501073821696 [16:46:57.129]收←◆541073821696 501073821696 [16:46:57.164]收←◆541073821696 501073821696 [16:46:57.200]收←◆541073821696 501073821696 [16:46:57.235]收←◆541073821696 501073821696 [16:46:57.271]收←◆541073821696 501073821696 openmv发送数据如下: 6248 6248 6249 6249 6249 6249 6250 6250 6250 数据格式不统一,不知道如何解决
