The project utilizes an AVR controller that can be used as a counter by being more involved with a PIC which has synchronous counter input. The PIC input can handle frequencies up to 40MHz.

The project is a 4-digit LED voltmeter and frequency counter that was previously based on PIC16C71 but was replaced by 28-pin device PIC16F876. The PIC16F876 is capable of driving 4-digit LED in ...

Everyone loves a bargain. Who doesn’t love a hacked oscilloscope? Well, it would be unusual for an oscilloscope company to teach you how to hack your own hardware. Besides, that’s already been done ...

The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 ...
