  • Is there a compiled hex file for the PIC16F686A? I see MikroC files but no clue how to compile them into a hex file to upload to the pic. Can you explain how to do that if there is no hex file? Thank you.

    Hi friend. there is hex file in that mplab x project. you can check in the sub directory. I use the mplab x ide v1.51 and xc8 v2.36.

  • The holes for the mounting tabs on the variable resistor are not big enough. The relay listed on the schematic does not fit the pc board. I have not been able to find a relay that does fit the pc board. Most holes are almost too small for the part. R11 through R18 resistor network is missing from the pc board and no provision for them.

    You can download and edit the design file. I use Proteus to design this PCB. It does not have enough models.

    Where do I find or how do I get the Proteus design files you used so I can modify them? Thank you.

  • Where is R11-R18 if the resistors between the PIC and display are R1-R7? I do not see R11-R18 on your pc board but they are in your schematic.
