Hi friends, I am using 2 MAX232, HCF4066 & PIC microcontrollers. I want to make communication of dial guage with PIC.
I have made connections for dial guage as given in image:
I tested dial guage by connecting to the PC through serial cable then dial guage is responds. Now I am able to transmit signal by enabling control pin of 4066 but not getting any response from dial guage. I am attaching the circuit diagram here. Please help me......
