hello,
I must make an application where receipt a data through rs232, I use the function _wait232 but never receipt nothing, I have the configuration by defect of the examples, my question is: is necessary to change some parameter for receive data by rs232?

Thanks a lot.

Hi,

a basic question just in case of : did you set the SW1 RX and TX switches to ON

thanks for your answer, yes, the switch is ON, the problem is only for receive, i can send perfectly, but never receive

[BrunoG]

I will check this, it's a long time since I did not use RS232 with VRStamp !

I have written a code using the Atmel stamp with a DS1620 and I want to use this in regards to the VR stamp. However, I don't know how to call out the pins of the stamp to a certain variable. Would something like this work:

ds1620_dq=p1in
ds1620_clk=p2in

to transmit data from one pin to another? And also, will the TxD work with RS232 in regards to a serial LCD (i.e. SerLCD from SparkFun)?

shamillion, I'm not sure to understand what is your problem, is it about individual bit access, or define preprocessor directive ?

Just saw that I completely forgot to answer to xaromar sorry, if you get this message and if you still need some help please tell me.

I'm attempting to use the VR Stamp's RS232 connections to receive a 9 bits of data from a DS1620 and send a message to a serial LCD. I used the Wait232 to receive the information and the Send232D8 to spit out the message with the temperature value.

To test, I tried sending a hello world message to the LCD. It worked, but it was scrolling really fast. After I made some changes, it stopped working.

Am I using the right commands to send/receive the data and is it possible for you to look at the code?

[BrunoG]

Hello,

what do you mean by scrolling really fast ?

yes put the code, I will try to see.

This is based on the RS232 example that showed up on the FluentChip help window.

#include <other.h>
#include <techlib.h>
#include <string.h>
#include "demo_io.h"
#include <stdio.h>

void main()
{
_Init232();

if (_GetBaudRate() != BAUD9600){
_SetBaudRate(BAUD9600);
}

for(;;)
{
_SendString232((long)"\n\rHello World\n\r");
}
}
