Serial problem between BasicStamp code and PBP code

[Demon]

If it is serial communication, I would start by sending a simple text to a PC in Stamp, then do the same in PBP.

Don't use your entire logic, just "HELLO". It will be much easier to show code here and debug.

Two questions.

Is there a serial ground connection between communicating modules (Not mentioned in pin assignments notes)

Is the Bluetooth module receiving commands and outputting serial. Scope checked etc.

Hi
Not sure about your code. But when using Basic Stamp syntax for serial. You should place at the top of your code.

Include "modedefs.bas"

In the back of the Picbasic Pro manual there is a section on the differences between PBP and Basic Stamp.

Hopefully you can make it work.

I have tried it with Include "modedefs.bas" and without. The code is not very long. What I need is for someone to look at the 2 files and see if they can tell why it won't work on the PIC. I have both the PIC and the Stamp and FT639 and Bluetooth module on breadboard. When I hook the 2 serial lines to the Stamp I can control the servos. When I remove the two serial lins and connect them to the PIC. it won't work. All the pin configuration is documented in the 2 files. lt appears to be a serial problem. When I power up the circuit it should automatically center both servos. It does with the Stamp but not with the PIC. Hope this helps.

You might get more help if you post your code directly. Some may not be able to open those files on mobiles.

Click GO ADVANCED at bottom right of a new post and use the code tags like this (CODE)...(/CODE) but using [ ].

My money is on a config.

What version of PIC BASIC PRO?

I am new to this. Have never posted before. Am 67 and trying to learn. I am using PBP ver 2.50C. The code files can be opened with notepad they are not very complicated or big. I don't know how to add my code files to a post. When I tried it the first time, it put them at the bottom of the post. The commands go over the air via Bluetooth then serially to BasicStamp then serially to servo controller. Works great. When I try it with the PIC nothing happens. I assume it is a serial problem from PIC to servo controller because it does not need the bluetooth at the start . It first sends centering command serially to servo controller to center servos. That does not happen. I have tried changing serial config from true to inverted the manual also says bit 15 can be for open or driven. Whatever that means.

No "NIBs" in pbp only bits, bytes, words & longs. Are you using "Default" configs ? have you gotten an LED to blink? I see NO "DEFINE OSC 4" in your code to tell PBP the pic is operating at 4 mhz
Are you using a crystal, a resonator or internal RC oscillator? Does you config statement reflect what you actually have ?

I have tried changing serial config from true to inverted the manual also says bit 15 can be for open or driven. Whatever that means.

open is an open collector where a pullup resistor pulls the output high whereas driven means an output transistor drives the output high or low.

Thank you for the reply. I had to rewrite the send routines because of the no "NIBS". Yes I am using default configs. I tried DEFINE OSC 4, INCLUDE "bs2defs.bas" and INCLUDE "modedefs.bas. I even tried their new program "meCONFIG" which gave me nothing but errors. I am using a 4 Mhz resonator on a PICBIT-18 board. I have used this board and PIC to blink an LED to make sure my PIC and board were working. The PIC I am using is a PIC16f84 /10 but I assume you can run a 10 Mhz at 4 Mhz with no problems. Thank you for the info on bit 15, good to no. I thought of disabling all interrupts, but don't know if the serial commands use interupts.
