    max232 capacitor value

    my controller resets wen serial_out or serial_in occurs..... i m using 16f877a.. i removed the wdt by "#fuses NOWDT" in the program.... here s my design one more mistake i made....i wrongly placed 220nF instead of 22pF with crystal osc.....ll it make any difference??

    need pic16f677a - CAN schematic

    thnks sir...but i already made the PCB with all the external components with 16f877a and mcp2515,mcp2551.....so i cant change my design again....it ll take more cost since i designed 5 PCBs....cost s not a matter.....but i hv very little time only.....still only 20 more odd days to go....so i m...

    need pic16f677a - CAN schematic

    yea...tats k....but i m doing project using pic16f877a only.....half way crossed....still CAN only left....so i planned to use mcp2515,mcp2551 along with 16f877a.....
