Experiments in video:
1. bulit-in SINE wave to channel1 -- frequency measurement
2. AC main pickup on channel2
3. Signal from ch1 to ch2 though my hand
4. Adjust pressure on leads to mix the two signals -- do FFT of the composite
5 . 1uF from CH1 to CH2 , 1k from CH2 to gnd shows phase shift
6. Open another program to make phase shift measurements
7. Set SQR1 to some frequency , assign it to Channel 3
8. RC step response

Board Bringup: LCD and Display Interfaces
Board bringup is one of the most under documented aspects of embedded development. This presentation will look at the various display technologies such as DisplayPort, DVI, LVDS, and other LCD interfacing methods with emphasis on how to bringup, debug, and validate them on new hardware. Using a case study, aspects such as interfacing timing, extended display identification data(EDID), and backlight controls will be discussed. Most embedded linux developers at some point in their career will be handed a piece of hardware that is untested. LCD bringup is one of the most challenging assignments for an embedded developer. This presentation intends to provide some core tools and methods for bringup of a new display interface. David Anders has previously presented at Embedded Linux Conference Europe 2010 with ""Board Bringup: Methods and Utilities"" and Embedded Linux Conference 2011 with "Board Bringup: Open Source Hardware and Software Tools".

Booming usage of Linux in embedded environments is creating an on-going demand to use this general-purpose operating system in industrial control devices and other fields, previously reserved for classic real-time operating systems. Talk covers success story of Linux based embedded ARM system controlling weight dosing in injection-molding process (plastics industry). Practical, universal (applicable to most SoCs), open-source solution is presented: embedded Linux, process control application and responsive, QT based GUI. Emphasis is put on problems occurring and solutions: advantages and disadvantages of RT-PREEMPT and Xenomai from a practical point of view. Presentation includes latency measurement results and techniques.
The talk is intended for all interested in using Linux in in real-time applications. Knowledge of embedded Linux and kernel internals will be helpful.
