EE 476: Homework 1 due At the start of your first lab period.
Read all of Lab 1.
Write the source code necessary to impliment the two programming assignments
for Lab 1.
- Reading from the schematics in the
hardware description, determine:
if the LEDs are lit when a logic high or
low is applied to the connector.
- if the switches outputs are logic high or low when pushed.
- For Lab 3 you will need to drive an earphone from a PortD pin. The
impedance of the earphone is around 500 ohms.
Estimate the output impedance of an i/o pin from the AT90S1200
