Topic: Problemas con librerias SD.h y SIM900.h (Read 1 time) previous topic - next topic

Hola a todos!

Tengo un problema, estoy trabajando en un proyecto de la U y necesito enviar datos a través de un shield GSM/GPRS y también almacenarlos en una micro SD. El problema es que cuando activo las librerías de SD.h y SIM900.h al mismo tiempo el programa no trabaja bien. Actualmente tengo la IDE de Arduino 1.0.

Aquí les dejo un ejemplo:

¿Podrías ser un poco más específico? ¿Qué es lo que no hace bien? ¿Cómo debería hacerlo? Cuanta más información des, mejor ayuda recibirás...y más rápido

La librería SD.h viene con el IDE de Arduino, pero la otra no, ¿podrías poner un link para saber si es la misma que tenemos/utilizamos otros foreros?

Para poner el código que utilizas puedes utilizar la etiqueta [ code ] (icono # en la barra superior), no es necesario adjuntarlo como archivo

PD: ¿Era necesario poner una encuesta?

Sorry por lo de la encuesta.... soy muy nuevo en esto...

Voy a adjuntar las librerías que he usado.

El programa debería inicializar, la SD, el sensor de presión, y la conexion Serial y Wire.... el asunto es que no lo hace...
Alguien me ha dicho que es un problema con la SRAM pero no se....

Este es el hardware que tengo, dos sensores, sensor de presión BMP085 (http://www.sparkfun.com/products/9694), y sensor de humedad (http://www.sparkfun.com/products/9569), que tienen también un escudo de GSM / GPRS (http://www.crcibernetica.com/sim900-gsm-gprs-shield-for-arduino/) y los R3 Arduino UNO. Aun me falta agregar un GPS. Otra cosa recuerden que estoy usando el IDE de Arduino 1.0

Muy buenas,

en mi caso tengo un Arduino UNO R3 con IDE 1.0.1, cuando utilizo las 3 librerías a la vez (SD, Wire y SoftwareSerial) el programa no me funciona bien, si utilizo por ejemplo (SD y Wire) me funciona sin problemas, si uso Wire y SoftwareSerial tambien funciona sin problemas, pero las 3 librerías a la vez no.

Saludos.
