This example program implements network control and access to the UDP6720 series DC power supply. First, let’s introduce the hardware used in this project: 1. UDP6721 DC power supply: controlled equipment 2. moxa serial port server 5150: converts the UDP6721 DC power supply device serial port connection into a network connection 3. Orange Pie Zero3: […]

A complete example of applying the CNN model trained on MNIST to recognize handwritten digit pictures (pictures from the Internet)
1 Think about how to apply the training model How can the MNIST model trained through CNN be applied to recognize pictures of handwritten digits (pictures come from the Internet)? This problem bothered me for 2 days. Many of the codes I found online were to train the model and call the model in a […]

Springboot integrates Klock to simply implement distributed locks
Can distributed locks be implemented with just one annotation? Doesn’t it sound exciting? Is it the springboot annotation stream again, implemented in a fool-proof way? Wait, simplicity is simplicity, we still need to see how it is implemented, and then see if it is suitable for our business. @Klock is also implemented based on Redisson. […]
