Sending multiple variables over SEROUT command?

Dmitriy

I am using a BS2p chip with a SFE ER-301 GPS unit.
Using the basic AEROGPS code provided in http://www.parallax.com/dl/docs/article/rambal-gps.pdf, I am able to get it to output some of the information I need.
Currently the output over the DEBUG screen is:
46:20:38.9,S,040:56:31.6,W
using an DEBUG code of:
DEBUG DEC2 laDeg,":",DEC2 laMin,":",DEC2 laSec / 10,".",DEC1 laSec // 10,Comma,"N" + (laNS * 5),Comma,DEC3 loDeg,":",DEC2 loMin,":",DEC2 loSec / 10,".",DEC1 loSec // 10,Comma,"E" + (loEW * 18),CR



How can I get the same output to transmit back over the serial cable?

I have tried the SEROUT command, but cannot get the same output to appear.· Single variable are easy to do using SEROUT 16, 240 [noparse][[/noparse]laDeg], but not having any luck matching to the DEBUG output.

Hello,

What is the code you’re currently using to send the same data serially?

The purpose of the basic stamp is to send two converted digital signals from an LTC 1298 PIC and the GPS data over 1 stream.

I've attached the combined and individual scripts.

It should be the same format as DEBUG. The following should act exactly the same as the successful debug.

SEROUT 16,$F0,[noparse][[/noparse] DEC2 laDeg,":",DEC2 laMin,":",DEC2 laSec / 10,".",DEC1 laSec ,Comma,"N" + (laNS * 5),Comma,DEC3 loDeg,":",DEC2 loMin,":",DEC2 loSec / 10,".",DEC1 loSec ,Comma,"E" + (loEW * 18),CR]


The // 10 after DEC1 is not necessary. It is implied.

So the $F0 just tells it to "get" the variable values from ROM?

No. $F0 is the hex equivalent of 240 decimal. It is the baud rate setting
for SEROUT.

Thanks, it works fine now.
