Chapter 1 Schematic Analysis
There are two crystal oscillators on the CC2530 core board: the first frequency is 32MHZ, and the second frequency is 32.768KHZ
When CC250 runs normally, it needs a high-frequency clock signal and a low-frequency clock signal.
The high-frequency clock signal is mainly supplied to the CPU to ensure the operation of the program.
The low-frequency clock signal is mainly supplied to on-chip peripherals such as watchdog and sleep timer.
Button IO port wiring (the button is connected to the bottom plate)
LED light wiring (LED is connected to the bottom plate)
