Support Forum » can't read or write to mcu
March 19, 2011 by Ace |
I was using my nerdkit today and everything was working fine, then I tried to write to the mcu again and got this: I wrote to the mcu once or twice before I got this error message and it worked fine. Now not only can't I write to the mcu, but when I move the switch to read mode, nothing happens. It's dead. I have checked all connections, tried different batteries, tried to upload different programs, and nothing. Any suggestions? |

Hi Ace, The most likely culprit here is a dead battery. Are you sure the new batteries you tried were fresh? Perhaps you can try connecting USB power to rule out a battery issue. The problem could also be a loose crystal, or maybe a loose reset line. If none of these things are the issue then it is possible your chip is just dead. Do you remember anything happening that might have caused your chip to fry? Perhaps a crossed wire or a spark? Humberto |

Hi Humberto, I've tried different batteries and no change. Didn't see any spark or crossed wire, everything seemed normal. Haven't even had this for 30 days, I thought the chip would last longer than that. It was working fine, then nothing. |

The chip will last a lot longer than 30 days, however I have a collection of them and LCD's at $15.00 a pop that "SOMEONE" did something to and now they no longer work. Ralph |
