Re: Unable to create C file

just to add an additional information on this topic.
if other files in the projects directory (other than .fcf, .hex, .fcf.001) are made hidden, then also this error appears without any extra information

Re: non busy delay routine..... possible?

hi kersing,

thanks for reply,
i totally agree with your suggestion. and i tried non busy delays using timer interrupts but i didn't succeed. i will be grateful if you explain it with the example.

thanks,

non busy delay routine..... possible?

hi, the need for this topic is to discuss the disadvantage of inbuilt 'delay' macro within FC. although it works perfect in many applications but in some applications where many interrupts are used and it is not required to keep processor in busy loop. in these cases 'delay' creates timing issues eg...

BOD in 16f676 chip

Hi,
I am using 16f676 chip and driving one 7 seg display, what my problem is the vdd is 5v and the rated BOD voltage for this chip is 2.1v which creates dimming effect on 7 seg display. if anybody has any idea to avoid that dimming effect of 7 SEG, would be greatly appreciated.

hi,
i am also looking for the same.
i m going to use the controller 16f1936, which is equipped with enhanced pwm, where dead band delay also included.
i just want to know that how those some enhanced features used or controlled through FC4.

Re: AC line voltage measurements

hi Martin,

i checked the optocoupler, it serves the purpose but it will be a costly solution.

glad to have help from you.

one more thing Martin, i was thinking to use V to F converter as replacement for costly Linear opto. is it possible?
soon i upload the circuit diagram,
