Dear all, I am trying to convert analog signal to digital signal using AT89S53. But that chip seem haven't any A/D converter. My question is, can I convert analog signal to digital signal only using AT89S53 or I need to change to another chip? If I can use AT89S53 for A/D conversion, how can I write the program code in C? Thanks
Using an external A/D has the advantage of mking it a lot easier to minimize digital noise in the analog part. Erik
