Help with PC interface and propeller

sgt_mathis

Could someone please help me. I am trying to write a program that allows me to a com port interfacing program like Hyperterm, PuTTY, or the Parallax Serial Terminal program. I wish to use the Prop Plug to facilitate this communication. I have tried using SimpleDebug.spin and FullDuplexSerial.spin but when i write a basic program to constantly send one test character, I get back nothing but garbage. Could someone please help me with this. I can't continue my project until I figure this out. Thanks

There's some code on this thread (http://forums.parallax.com/showthread.php?p=675748)
that might be of help to you.

Tell us a little more about what you are trying to do and share the code you are using.

I've done this with no problems. Are you using a crystal or the internal oscillator? The timing is too precise for it to be stable without an external crystal or resonator.

SimpleDebug, written in Spin, also has a relatively low max speed. I've used it for 9600 bps with an 80mhz clock. It won't do 115,200.

I am working on a project in which we are trying to make a GPS autopilot system for a model aircraft. I am hoping to use a PC, through the previously mentioned programs, to give the system it's waypoints just prior to takeoff. The test source that i'm using is posted below:

OBJ

console : "FullDuplexSerial"

VAR

PUB main
console.start(31, 30, 0, 9600)
repeat
console.tx("p")

If that is the whole code, then you work with the internal RCfast clock, which is not precise enough.
Include something like this at begin:
CON
_clkmode = xtal1 + pll16x
_xinfreq = 5_000_000

CON
_clkmode = xtal1 + pll16x
_xinfreq = 5_000_000


OBJ

console : "FullDuplexSerial"

VAR

PUB main
console.start(31, 30, 0, 9600)
repeat
   console.tx("p")

Do you have the console line indented like above? If not, you'll only get a single "p"
What happens if you change the "p" to 65? Do you get a line of A's?
