Meeting with Keith Better understanding of system

requirements Emphasis on relative outputConfirmed HK details to be measured○ Temperature of LED is important

Ideas for LED temperature measurementsFiber couplers

GUI work

PIC work Bare outline of code needs

0. Include libraries1. Define variables used2. Initialize pins (clear PORTA, PORTB, configure pins as inputs vs. outputs)3. Actual code    a. Take in measurements from the circuit (2x voltage for DC-

DC current, 2x voltage for DC-DC voltage, 1 voltage for LED current, 1 voltage for LED voltage, temp. sensor input)

    b. Send measurements to USB connection    c. Read user inputs from USB connection    d. Output voltages corresponding to these user inputs

Researching USB to PIC connection Advice?

General circuit layout

Next steps Create a detailed PERT chart based upon

descriptions from Keith Use specifics from Keith (LED datasheets,

etc.) to ID components so that we can begin detailed designsPrecision resistors to measure current with (current

plan: measure voltage across resistor in series with component to determine current—other ideas?)

Temperature measuring componentsLook into how to check that the x-ray output is

correct (how MCA works—look at site (esp. intro information))
