Description
1. Lab 2 Overview
In Lab 1, you created schematic symbols and PCB footprints for several components. In this lab, you
will place and connect those components in a series of schematic sheets. Your schematic sheets
represent the components found in your embedded system and how they are connected to one
another.
2. Pre-Lab
1. Open the Altium Designer Project that you completed in Lab 1 by clicking on the
ECE315.PrjPcb PCB Project File.
2. Watch the following videos to complete 03-MCU.SchDoc and 08-USB_To_UART.SchDoc.
Schematic Capture Basics
Schematic Capture Tutorial
Use the information in the videos to complete pages 3 and 8 of the schematics. Once you
are finished, your schematics should look like the following images:
3. Pre Lab: What to Turn in
File Name Description
LastName_FirstName_Lab2_Altium.zip Altium Project ZIP file. Delete the History folder
before creating the ZIP file.
LastName_FirstName_Lab2_Sch.pdf PDF of schematics with pages 03 and 08
completed.
Use FileSmart PDF to generate the
schematics. You can use the default settings,
but only include the .SchDocs on the 3rd page of
the dialog.
4. Lab Work
a. Complete 03_MCU.SchDoc
Verify the following off sheet connectors are assigned to the GPIO pins listed
below:
Signal Name Connected to
SWDIO PA13
SWCLK PA14
BUZZER PA1
MCU_RX PA10
MCU_TX PA9
SPI1_MOSI PA7
SPI1_CLI PA5
Note the following requirements:
o All nets are required to have net names.
o Add Non-Specific No ERC connectors on each pin that is unused.
b. Complete 02_Power.SchDoc
Add a single instance of the TLV73333, along with any supporting passive
components, required to generate a 3.3V output from the 5.0V power rail. You
can use the “Typical Application Circuit” from page 1 of datasheet to determine
how to properly connect the device.
Note the following requirements:
o Set Cin and Cout to be 10uF capacitors.
o Connect the Enable pin to 5.0V
o Add Test Points for 5.0V and 3.3V
o All nets are required to have net names.
o Add Non-Specific No ERC connectors on each pin that is unused.
c. Annotate your schematics
In order for you to transfer our schematic design to a PCB document, every component
must have a unique reference designator. Altium provides tools to do this for us.
Watch the following video that will instruct you how to annotate your schematics.
Annotating Schematics
1. Select Tools→Annotate Schematics
2. Altium will open a window that will show you how it will auto number your
reference designators.
1. Select Update Change List, then OK
2. Select Accept Changes
3. In the pop up window, Select Validate Changes, then Execute Changes, then Close.
If Altium detected any errors that need to be fixed, the green check mark would
be a red X indicating you have to fix something.
4. Post Lab: What to Turn in
File Name Description
LastName_FirstName_Lab2_Altium.zip Altium Project ZIP file.
LastName_FirstName_Lab2_Sch.pdf PDF of completed schematics
Use FileSmart PDF to generate the
schematics. You can use the default settings,
but only include the .SchDocs on the 3rd page of
the dialog.
