I recently received a few pic16f716 chips and decided to make a simple blinking led program to test if they are usable. I'm using a red usb-pic programmer that seems to work well for most chips, but when I attempted to program this chip, I receive either a "received data error" or "Rom error at 0x0000...Good 0x2805...Bad 0x3fff." I can't believe these are defective because my supplier Newark Electronics is good at quality. Any help would be appreciated. |

well, if delay does not fix problem, then the software may not support this chip well. Try to use ICSP connection the see if any thing different. |

I tried your suggestions by double-checking the code protection was off and adjusting the 16f716's program delay option in the programs chipinfo file from 20 to 100 and even a thousand. Unfortunately, I still get the same errors. Perhaps the 16f716 was never meant to be used by the programmer. However I'm still open for suggestion to save a couple dollars. Thanks in advance! |

make sure your CFG security bit is off.
if the CFG bit is fine, then increase the "Delay=" parameter. This will slow done the programming speed and increase chip compatibility. |
