#138065 - Did you design the product? Responding to: ???'s previous message |
Or are you trying to reverse-engineer to defeat the counter?
If you are the design of the product, wouldn't you know where the counter is and how to reset it/ modify it's action? Sounds like you are tryinig to "crack" the code to get more than 3000 uses. The P89V51RD2 does have a security code feature to prevent read out of the code. The only way to repogram the P89V51 is to erase the chip (and loose the exsisting code) and reprogram it with your own code. Joe |
