Proyecto 29 - OPTREX DMF-50773NF-FW LCD Module

9 de enero de 2016

En tutoriales anteriores vimos como mostrar gráficos en displays de 240x64 pixels.

El modelo con el que vamos a trabajar hoy es un OPTREX DMF-50773NF-FW-ACE de 240x128 pixels. Utiliza el controlador Toshiba T6963C y por suerte para nosotros es compatible con la librería u8glib.

La forma de proceder es la misma que en los proyectos 13.1 y 13.2. Se instala la librería y se desmarca el constructor correspondiente al controlador utilizado en el módulo LCD.

Proyecto 29.1 X-Ray Generator Interface

Esquema

La conexión de este módulo es un poco más complicada que el POWERTIP utilizado en proyectos anteriores. Esto se debe a que necesita de tres tensiones para funcionar.

Una alimentación de +5V proporcionada por Arduino para las señales lógicas, otra de +12V para el CCFL Backlit, que es un pequeño tubo fluorescente para retroiluminar el panel y una tercera alimentación negativa de aproximadamente -13,5V para en LCD. Nada que no se pueda solucionar con la fuente de laboratorio que hicimos en el Proyecto 28.

Otra solución es conectar los +12V del Inverter, al pin VIN del Arduino y con los +5V del regulador interno alimentar el LCD.

Para más detalles consultad el datasheet al final de la página.

Sketch

La imagen que se muestra más abajo corresponde con un diseño propio y simplificado de la interfaz de un generador de Rayos-X. De momento es sólo una imagen .bmp que he subido al LCD pero con el tiempo espero hacerlo realidad.

No lo incluyo aquí el sketch por ser muy extenso. Se puede descargar al final de la página.

Proyecto 29.2 - RTC with Meteo Icons

En los siguientes ejemplos de aplicación del módulo OPTREX DMF-50773NF-FW-ACE conectaremos un RTC DS3231. Puedes descargar la librería del RTC aquí.

En un primer ejemplo mostraremos la fecha, la hora y la temperatura. Y en un segundo sketch voy a incluir varios iconos meteorológicos.

Esquema

El esquema de conexión es prácticamente igual que el ejemplo anterior, solo hay que cambiar la señal READ del pin A4 al D3 para poder conectar el RTC en los pines SDA y SCL del Arduino.
