SPI read and write functions: Each read and write operation of CC1020 includes 7 address bits (A6:A0), 1 write operation bit (write high), and one byte of data. Before the write operation, PSEL must b
TD6600 relay protection tester verification device is an instrument dedicated to testing the technical performance of relay protection testers. It can accurately measure multi-channel AC/DC voltage, c
The internal instruction cycle of DSP is high, and the main frequency of external crystal oscillator is not enough, so most DSP chips have PLL. But each series is different. 1) TMS320C2000 series: TMS
Dr. Dot's micro quadcopter successfully flew naked for the first time. Naked flight means that the PID control of the gyroscope has not been turned on, and it is powered on to fly. We can see in the v
