Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program): VCC: 5V,GND: GND, DIN: P00, CS: P01, CLK: P02 VCC and GND Do not reversed, it would burn the chip 51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines
Note:
1.VCC and GND do not reversed, it would burn the chip
2.51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines
