Hi dear friends,
Thanks for providing the opportunity to interact with you experts!
Here I want to perform parallel to serial data conversion. Therefore I am using 74HC165, 8-bit parallel-in/serial-out shift register.
I need C code to read & store the fault status into Variable( say unsigned char). I tried below C code but its not working.
Basically I have an 8 Window Annunciator product where I want to read the Eight different Fault status. These faults can be either Logic 0 or Logic 1. Now these Eight status shall be collected into a Variable(datatype: unsigned char, as value 0b00000000/ 0b11111111 is possible)
Hardware logic is illustrated as shown in fig(A):
D0 to D7 are eight fault status which can be either Logic 0 or Logic 1.
C Code to read & store the status is attached as follows:
So kindly suggest the correct C code to read & store the fault status into Variable.
Thanks!
