EE 476: Homework 1
due At the start of your first lab period.
- Read all of 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.
- Estimate the Thevinin equvalent output resistance of an i/o pin from the
AT90S8515 data sheet. There will be two separate estimates corresponding to
whether the output is logic-high or logic-low.
