Practical SXB Book Code Problems

DigitalDj

I have been playing around trying to learn more of the code for the SX and have run across a snag in the Practical SX Book. I have typed this code in but I get nothing. I tried searching the forum because I had read at one time there was some typos in Jon's book. So I wanted to see if I was doing something wrong or there was an error.

' -------------------------------------------------------------------------
' Program Description

Led Blinky 3

DEVICE          SX28, OSC4MHZ, TURBO, STACKX, OPTIONX

Led  Pin RB.0

IsOff  Con 0

Start:
Do
  Led = IsOn
  Pause 500
  Led = IsOff
  Pause 500
Loop

Hello,

One thing that I don't see in your code is where you define the pin as an output. If it
isn't defined as one you won't see any change in the LED.

Indeed you have a typo, Kevin; I just checked a hard-copy and you omitted the OUTPUT specification for the LED pin.

AH HA! I didn't catch that! That was a simple mistake on my part. I do really like your book and can't wait until it is done. Very well written and easy for the newbie if he makes sure to read everything so output changes it so that what is in the constant specifies output.

Thanks Guys,

Kevin
