SPI interface to real risk, dynamic LED tube showed that the experimental data. 1, the program through the SPI interface to drive the output data to the HC595 chip data management simple LED display. 2, dynamic scheduling by the on-chip Timer 1 interrupt generation, interrupt cycle 5mS. 3, the internal crystal oscillator 1 M, the program single-task mode, the software delay. 4, for this experiment JP1 plug in all the eight short blocks, JP6 (SPI_EN) short block.
