actally, i have read the documentation, and have been working on it. and i connected 2 I/O pins of the 8051 to the 2 pins of the smart card reader, and then try to count the number of translation from low to high in the CLK signal, if 32 low to high is counted continuesly and the signal is the same during the 32 transitation, then i count the data signal to be "1" if the data is high. But i found that this method is not reliable, it causes problem in sometime, so i am seeking for any other method for doing so. |
