    Re: Can't program a 12LF1840?

    Hi All,

    SOLVED!

    I knew I was making a stupid mistake and it only took me a day to see it!

    I was powering the LF part from 5v.

    Set to 3.5v and all working.

    Thanks for the replies.
    I had already selected 12LF1840 on programmer and Microcode (I had also tried 12F1840 just to be sure).

    But thanks,

    Thanks for the replies. Unfortunately the simple diode solution is no use! The Tx and Rx modules need a solid 5v. Any less and their range falls dramatically.

    Hi,

    If you are going to use a seperate 5v supply say the 5v from the other PC I would strongly recommend using an optocoupler to monitor the 5v.

    Hi,

    I would detect the 5v from the PC's USB socket. When 5v disappears check again for about 400mS to allow for spikes then send your serial data to the other PC.

    Hi,

    Thanks for the reply. But the part was definitely a transmitter. From what I remember it required no external xtal or inductors just a tuned aerial circuit. Will keep on searching.
