Just a resistor will do usually. The current across the pull up resistor will need to be less than the circuit draws. With a 10K pull up you have a resistor from 13V to the 5V supply. That is going to ... |

I've looked at the ICSP guide, and the ICD2 guide. These say to
use a pullup resistor and a capacitor to ground, and a diode between
MCLR and the RC network (isolating Vdd from 13v), or just a res ... |

Hi all.
I've been asked to take a look at someone elses circuit. They're using an ICD2 to program and debug the PIC (18F252).

how you done this preample?
can you paste your code here?
thanks!
Simple really

Ohhh...
I was thinking in transmit some data codes over rs232.. but that is ok.
FWIW, I've used short bursts of RS232 data (with a preamble of 0x55AA), and I've never had any problems ... |

Hi
It is possible run program from external memory on Flash Device?
I suppose it would be, in principle.
If you could put some code into high ROM on your device, you could then load instructi ... |

I'm going to put in a shamless (or shamefull) plug here.
I work at Micron Technology and we have some nice CMOS visual sensors here. We've had some nice reviews about them too. I'm trying to get ... |

Greg,
One sure thing, is you have to store image/s in an external memory.
I�ve seen that OV uses a propietary protocol to transfer images, a bit complex.
I would like to see o ... |

You might want to consider something like a DS1307 real-time clock chip. This is specifically designed to draw little power. Then sleep the PIC with the watchdog, and when it wakes, read the 'real' ... |

The datasheet is mostly to blame. The only thing it mentions is that the device is a wide-range part, from 2.0v to 5.5v. And only the graphs towards the end show that for operating at very low voltage ... |

Yes Pete is right, my mistake. It might be a better idea to use the LF part.
This one really bit us on the arse. We made a short run of devices, which all seemed to work fine.
We then made lots ... |
