Control of a single modulesimply input port to the CPU
3 more modules cascade input termination module of a CPU2 output termination module input and output of the two modules is terminated with the input end of the first three modulesand so on. ..
51 MCUfor example:
- VCC → 5V
- GND → GND
- DIN → P22
- CS → P21
- CLK → P20
- 1.VCC and GND is not reversedit would burn the chip!
- 2 the P0 port control 51 microcontroller must be connected to the pull-up resistorit is recommended that the resistance of 4.7K–10K
- Please lattice first inserted into the round hole seatthen inserted into the round hole Block PCB board welding. Lattice word side facing the surface order from left to right pin 123456. PCB board 1 foot square pad!
- 4 as cathode of the electrolytic capacitors long-leggedshort legs for the negative; ceramic capacitors without the positive and negative points.
- A single module can drive an 8 * 8 common cathode lattice
