Medidor Online De Temperatura Y Humedad De Bajo Consumo
Medidor online de temperatura y humedad de bajo consumo Estudiante: Jesús Santiago Fernández Prieto “Ingeniería Técnica de Informática de Sistemas” Consultor: Jordi Bécares Ferrés 11 de Junio de 2013 When I read commentary about suggestions for where C should go, I often think back and give thanks that it wasn't developed under the advice of a worldwide crowd. (D. Ritchie) A mi familia, novia y amigos. 2 Resumen Para este proyecto se ha diseñado un dispositivo con capacidad de conexión a Internet a través de un punto de acceso WIFI para el envío de datos y alertar en caso de posibles temperaturas y humedades críticas, definidas con un valor mínimo y un máximo. El diseño de este dispositivo se ha hecho teniendo en cuenta el reducir el consumo de energía para maximizar autonomía. El dispositivo está basado en una mota LPC1769 que posee un procesador Cortex-M3 de ARM el cual ejecuta nuestro programa desarrollado. Este programa hace uso del sistema operativo FreeRTOS (Free Real Time Operating System) que facilitará y nos asegurará estabilidad. La mota llevará conectada un chip WiFly que se usará para poder conectarnos por WiFi al punto de acceso. Cuenta además con un sensor SHT15 que permite, a la mota, tomar las mediciones de temperatura y humedad relativa. Estos serán posteriormente enviados al servidor. En caso de que en alguno de esos valores esté fuera del rango de seguridad se avisará al usuario a través de dos leds conectados también a la mota. Se le puede configurar una dirección de correo electrónico donde se enviarán alertas para enviar un correo al usuario advirtiéndole de un posible problema. -

The ZEN of BDM
The ZEN of BDM Craig A. Haller Macraigor Systems Inc. This document may be freely disseminated, electronically or in print, provided its total content is maintained, including the original copyright notice. Introduction You may wonder, why The ZEN of BDM? Easy, BDM (Background Debug Mode) is different from other types of debugging in both implementation and in approach. Once you have a full understanding of how this type of debugging works, the spirit behind it if you will, you can make the most of it. Before we go any further, a note on terminology. “BDM” is Motorola’s term for a method of debugging. It also refers to a hardware port on their microcontroller chips, the “BDM port”. Other chips and other manufacturers use a JTAG port (IBM), a OnCE port (Motorola), an MPSD port (Texas Instruments), etc. (more on these later). The type of debugging we will be discussing is sometimes known as “BDM debugging” even though it may use a JTAG port! For clarity, I will refer to it as “on-chip debugging” or OCD. This will include all the various methods of using resources on the chip that are put there to enable complete software debug and aid in hardware debug. This includes processors from IBM, TI, Analog Devices, Motorola, and others. This paper is an overview of OCD debugging, what it is, and how to use it most effectively. A certain familiarity with debugging is assumed, but novice through expert in microprocessor/microcontroller design and debug will gain much from its reading. Throughout this paper I will try to be as specific as possible when it relates to how different chips implement this type of debugging. -
