My problem is how to read these bits which comes to 16 bits(2 bytes)?then send these bytes serially out to parallel out puts.To explain more suppose we have 16 push button that is input to two shift register and on the out put we will get them serially,but to keep the push buttons pressed alive and active ,we have to some how keep them on (say if they are led) ,what I have done is sending back the bytes we get serialy through SIPO(595)and a driver (ULN) to the paralell inputs.
I have made some codes but do not work.
