Hardware |
|
| From figure 1which show Completed circuit of Frequency counter 0-50MHz . From figure 1 we selected PIC16F84 is main device of circuit . The counter's input signal is amplified by MPF102 and 2N4403 and clocked into MCU through its RTCC input where the count is accumulated.Then 7 digit ASCII equivalent is sent to and and displayed on the 16 character LCD |
