Using the Breadboard Canvas

Introduction

This guide explains the use of the Breadboard Canvas with the Analog Discovery Studio. The Breadboard Canvas is used to host all of the user designed circuitry and connects to the Analog Discovery Studio through the magnets beneath each of the four standoffs in the corners of the Breadboard Canvas. The Breadboard Canvas includes the following features:

  • Two 630 tie-point solderless breadboards
  • Three 100 tie-point voltage rails
  • Three user LEDs
  • Two user buttons
  • Two user switches
  • Four power supply switches
  • Four power supply indication LEDs
  • Two 24 tie-point breadboards for user IO and power supplies contact points

Note: This guide only pertains to the Analog Discovery Studio.


Demonstration

1. Setup

1.1

A Breadboard Canvas comes with the Analog Discovery Studio. The Breadboard Canvas is attached to the Analog Discovery Studio through magnets beneath each of the four standoffs in the corners.

1.2

Lift the Breadboard Canvas off of the Analog Discovery Studio. Note that the magnets are fairly strong to ensure that the Canvas does not accidentally fall out of the Analog Discovery Studio, so extra effort to remove the board may be required.

1.3

During shipping, a piece of foam is placed underneath the Breadboard Canvas to protect the contacts that connect the Canvas to the Analog Discovery Studio. Remove this foam and place the Canvas back onto the Analog Discovery Studio.

After replacing the Breadboard Canvas back into it's slot, connect the Analog Discovery Studio to the host computer using the included USB Type B cable. Connect the included 15V power supply to the Analog Discovery Studio and turn on the Analog Discovery Studio by flipping the switch on the left-hand side of the platform.

2. Using the Breadboard Canvas

The Breadboard Canvas has multiple types of user IO available for convenience.

2.1

The Breadboard Canvas has four different power supplies that are controlled by four power switches in the top right hand corner of the Canvas: +3.3V, +5.0, both ±12.0V, and both of the ± variable voltages. The variable voltage ranges operate between +1V to +5V for V+ and between -1V and -5V for the V-; both of these values are set through the Waveforms “Supplies” instrument. More details on the WaveForms Power Supplies instrument can be found in the Using the Power Supplies guide.

The Supplies instrument in the WaveForms software must be enabled for the variable voltages to work.

2.2

Three separate user LEDS (red, yellow, and green) can be enabled by providing a logic signal between 1.8V or a 5.0V logic signal. The LEDs can be enabled through the respective inputs labeled LED RED, LED YLW, and LED GRN.

2.3

Two user IO buttons labeled BTN 1 and BTN 2 are present to the left of three user LEDs. The outputs of the buttons can accessed through the respective outputs labeled BTN1 and BTN2.

The 5.0V power switch must be enabled for the buttons to work.

2.4

Two user IO switches labeled SW1 and SW 2 are present to the left of two user buttons. The outputs of the switches can accessed through the respective outputs labeled SW1 and SW2.

The 5.0V power switch must be enabled for the switches to work.

3. Example Project

Demonstration project using the Breadboard Canvas

3.1

Connect connect the 2×10 MTE Cable set that is included with the Analog Discovery Studio to the Digital I/O MTE Connector on the ADS. The MTE Cable connector is notched so they only fit one way.
