Recently, when I was tuning the srio communication of 6672 and using nwrite to send data, a 6672 chip had data misalignment. Specific phenomenon: 1024 sequential numbers 0-255 0-255 0-255 0-255 were s...
1. Introduction to the original plan
The original solution uses Zigbee+wifi relay and 8266+cc2530X2. The 2530 blankets on the blanket continuously collect data, which consumes a lot of power. In the i...
