Chapter 1: Basics of RPi.GPIO Module Importing the Module To import the RPi.GPIO module: import RPi.GPIO as GPIO By doing this, you can refer to it as GPIO for the rest of this script. You can check if the module was imported successfully by throwing an exception: try: import RPi.GPIO as GPIO except RuntimeError: print(“Error … Read more
The previous LED light used the output function of GPIO, and this time we finally need to use the input function of GPIO. Since the use of this human infrared sensing module is relatively simple, we will create a simple human sensing alarm system in conjunction with the previous buzzer after the experiment is complete. … Read more
Clickthebluetext MindSpore Follow us Recently, the MindSpore open-source community has closely collaborated with Orange Pi to pre-install the MindSpore AI framework on the Orange Pi Ai Pro development board’s system image. This will continue to evolve in subsequent version iterations, currently supporting all network models covered in the MindSpore official tutorials. The official system images … Read more
For detailed information, please refer to Section 3.13.6 of the “OrangePi_Zero2_H616_User_Manual_v4.0.pdf” regarding USB camera testing. Steps are as follows: 1.First, plug the USB camera into the USB port of the Orange Pi development board.2.Then, use the lsmod command to see that the kernel has automatically loaded the following module: orangepi@orangepi:~$ lsmod | grep uvcvideo | … Read more

While packing up my things, I came across this little gadget and took it out to play with. Orange Pi Zero Plus (512MB) H5 @ 1.2GHz, performance is decent. 512MB DDR3. DC 5V DC-IN, it can be powered directly by DC, USB, or Ethernet. Some features, let’s talk about this CVBS. It has a decent … Read more
01 Background Introduction Due to factors such as network structure and training methods, most neural network models have format restrictions on input data. In the field of computer vision, these restrictions are mostly reflected in image size, color space, normalization parameters, etc. If the source image or video does not meet the requirements of the … Read more
In the previous introduction, we discussed how to develop AI inference applications based on Orange Pi AIpro, and learned that before inference, the original network model (which could be PyTorch/TensorFlow/Caffe, etc.) needs to be converted into an .om model. Only then can we call the Ascend aclmdlExecute and other model execution interfaces for model inference … Read more
