CH452按键和显示板驱动程序,采用级联方式,模拟SPI口一次发送24位数据.每级120个灯和120个按键.采用查表换算.-CH452 keys and display drivers, concatenation, a simulation of SPI I sent 24 data. Each level 120 lights and 120 keys. Using Lookup conversion.

通过查表实现程序散转 使用ARMulate软件仿真调试-Scattered look-up table to achieve change through the program debugging using software simulation ARMulate
