Re: [HamBrewers] Help needed in completing a classic 8digit LED counter kit

 

Thought I might add the reward for hexing me the code(first workable hex) ..... one free LMX2322 freq.divider. Am too busy to study compilers so I'll leave this for you. Please email me the hex and not post in the reflector.

73ees,
Pat

Hi all,

My dual 7217 with 7017 and a 6.5Mhz crystal osc 8 digit counter 3.5 Mhz common anode LED kit blew up with one of the 7217s in smoke. The LEDs did not light up and am hoping to replace the circuitry with a PIC16F84+4051 combination from here:- http://www.qsl.net/y/yo5ofh//pic/digiscale.htm

Could a kind soul help me with hexing the source code from C please for my common anode display please. PIC is 16F84A
