Dear all,
we want to use an a to d converter with 89c51rd+ microcontroller and connect 0 to 5 volts variable voltage as analog input using a preset and get different addresses to the microcontroller.
what is the clock frequency that we should feed to the adc0808?
and how to generate it?
we are using 12mhz crystal with microcontroller.
Our eariler problem of counting external events is solved. we had to use only debouncing software and no hardware changes were made.
thanx for all your support.
