    Re: USB port restarting QickStart

    I reloaded the FTDI drivers (2.08.24) and the problem persisted.

    However, if I open (and enable) the Parallax Serial Terminal, the problem goes away.
    Note here that the Quickstart is not sending...

    hi Stefan did you resolve this?

    I have a similar problem on a HP laptop but with an interval of about 35 seconds between resets, and I get the same symptoms of a double-blink on the blue LED...

    Re: reset versus F10 versus F11

    I'm now confident that the problem was with my code. i.e. its behaviour on reset assumed that the ECU required a 'fast init' to wake it up ... which is certainly does need if I am loading to EEPROM,...

    hey Rick, that occurred to me but it doesn't explain why it works fine without the delay in there when it runs after a load from EEPROM.

    reset versus F10 versus F11

    Hi all,

    the behaviour of one of my programs is not consistent between the following 3 events:

    (a) manual reset (pushbutton on Resn)
    (b) compile and load RAM
    (c) compile and load EEPROM

    For...

    - feed on some heatshrink tubing on each wire
    - strip the...
  12. Re: First Spin Podcast - For those who've NEVER programmed/worked with Props before

    I love it.

    It's great just to hear people discussing the propeller.

    And I love your perspective of coming from the angle of a total n00b ... keep it coming!

    cheers,

    assuming that you're using one of the LCD objects from the library (e.g. LCD_16x2_8bit.spin),
    you can simply move to the start of the row you want to clear, then write spaces

    for example, if...
