I use a double-shielded cable to transmit signals. The inner signal line (3V sawtooth wave) drives the shield layer (middle layer) after passing through the AD823 in-phase buffer. The outer shield lay...
This concept watch launched by a Korean designer seems to have no dial, and of course no hour and minute hands, only a transparent ring. The designer certainly did not forget about this, but actually ...
After a few days of study, I finally finished drawing the PCB of the CC2540 Bluetooth module. Because I bought the CC2541 Bluetooth development kit, I drew the CC2540 USB Dongle this time. Schematic d...
The program can be displayed normally in the internal oscillator mode, but there is no display when it is set to the external crystal oscillator. I have not found the reason yet, please help me!...
