I don't know why. Both CE and the microcontroller say it is RS232. But why can't it receive? A friend said it's the level of DTR pin 4. Is this the reason? If so, can the level be modified by using th...
What I want to do is a temperature collection and transmission system. I don't understand the content of the Zigbee protocol stack, nor do I know how to transmit data between Zigbee and 51. I would li...
Materials needed: solar motor, good brothers, 6 screws, wires, iron sheets (with holes, 2 pieces), rechargeable batteries, and fans.1. Parallel connection, solar panels, each panel has a positive pole...
At present, the existing manual meter reading methods are far from meeting the needs of modern management, and the resulting increase in line loss rate will inevitably affect the development of the po...
