1. Power saving (since the liquid crystal itself does not emit light, the power consumption is low) 2. It can only be driven by low-frequency AC voltage, and DC will damage the liquid crystal 3. Types...
I want to control a 380V three-phase AC asynchronous motor. Currently, the options are AC contactors and solid-state relays. However, both are large in size. The system requires 380V AC and power with...
J-link connection problem1. Keil5 can connect to J-link and burn to the board, but J-falsh cannot connect to J-link, let alone burn to the board. What is the reason? Is J-falsh set incorrectly? (Are J...
I soldered two boards in total. When I used the simulator to do the target congfiruration test on one board, it showed success (at the bottom of the report result); the other board always showed failu...
I would like to ask all the experts, can you tell me how to find the signal line for unlocking and locking the car, and how to distinguish the types of signal triggers in a simple, convenient and fast...
