blob.code() 返回一个16bit数字,每一个bit会对应每一个阈值。举个例子: blobs = img.find_blobs([red, blue, yellow], merge=True) 如果这个色块是红色,那么它的code就是0001,如果是蓝色,那么它的code就是0010。注意:一个blob可能是合并的,如果是红色和蓝色的blob,那么这个blob就是0011。这个功能可以用于查...

只要是安信可的ESP32Cam开发板(带烧录底板)都可以,microSD卡(TF卡)必须256MB~4GB,格式化为FAT格式,否则无法写入人脸信息 目前找到的最便宜、质量最好的是这家:1688的杰兴泰电子,只要￥27包邮就可以拿下开发板和烧录底板其它店多是￥30以上,质量还没他好(之前别的店买过两次,各坏一半气得我半死) 有些店家买...

MySerial_stm32.println("usart test!!!"); delay(1000); } HardwareSerial库实现了对串口1的使用,HardwareSerial类在声明对象时接收一个输入参数(0、1、2),分别代表Serial、Serial1、Serial2; 如上图: ESP32CAM的TX也就是U0TXD对应引脚1。 ESP32CAM的RX也就是U0RXD对应引脚3。
Finally, the values forssid(name of your WiFi network) andpasswordhave to be adjusted. Then you can compile the code (check mark/verify) and then upload it to the connected ESP32. First Test of the Camera As soon as the upload was successful, you can open the serial monitor (under Too...

The value in brackets with % sign provides number of frames that differ from the test pattern. See code inline comments for more information on this functionality. QR Recognition ESP32_CAMERA_QR contain QR library. To do so, runmake menuconfig, openESP32 Camera Demo Configurationmenu option and...
Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name "XIAO" here represents its half feature "Tiny", and the other half will be "Puissant". Seeed Studio XIAO ESP32S3 Sense integrates camera sens...
