Now I want to control 6 TM1640 chips, each chip needs two IOs, sdata and sclk. Now connect all sclk together, and connect the sdata of the 6 chips to 6 IO ports respectively. The circuit seems to be n...
After learning MCU, if I want to do some projects, do I also need to learn things like sensors? Use specific sensors for specific problems. Also, is there any relationship between PLC and MCU? I just ...
I started to use CC2430 to do Zigbee. I saw the circuit and hex data of SmartRF04EB. I also just got an emulator made by a domestic company. It is very simple. In addition to C8051F320 and LDO, there ...
