16F84A frequency counter HEX file

Postby VU2SNK » Wed May 13, 2015 2:08 pm

It seams due to non availability of 16F84A in the market, the HEX file for making the still displayed circuit
for the frequency counter, has been removed from the Download section.
Can anybody supply me with the same. There 2 No's of 16F84A laying with me. I have a PicKit2 clone programer,
so there will be no issue of programing one of them for the counter. I also happen to have acquired a PCB
for this project.

Hello MVS Sarmaji,
Thank you for your hand of help.
My mail address is satish.vu2snk1@gmail.com
Does your file differs from the one from the link
given by VU3CNS on this site?
I have yesterday downloaded the file from the link,
and programed the 16F84A with the same.
Actually my assembly is almost completed less the IC socket,
2 No of 470 ohms resistances and a0.02uf capacitor. I hope to get
the components today ( I stay 5 Km. from the city market ).

I must thank you both VU3CNS and Shri MVS Sarma for your prompt help with regards
to the frequency counter.
I have completed the assembly yesterday, and the frequency counter worked without
any problem.
I have yet to calibrate it's 4 Mhz clock oscillator and try the IF shift switches.
I tried the counter with AD 9850 DDS Vfo.
Any more comments and suggestions are well come.
