自己在做SST51与TLC1543的连接,而SST51集成SPI接口,想咨询TLC1543怎么直接用SPI接口控制,不需要模拟时序。请指教,谢谢

Wang, 你好!
PIN连接如下:
TLC1543's /CS --> CPU SPI's /SPISTE;
TLC1543's I/O CLOCK --> CPU SPI's SPICLK;
TLC1543's DATA OUT--> CPU SPI's SPISOMI;
TLC1543's ADDRESS--> CPU SPI's SPISIMO;
TLC1543's EOC --> CPU SPI's GPIO;
你可参考附件资料。
另: TLC1543是比较老点的ADC,可以用ADS7956 - 10 bit, 1 MSPS, 12ch input SAR ADC.
