Using the Breadboard Canvas (Under Construction)
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.
- An Analog Discovery Studio host platform
- A Breadboard Canvas
Note: This guide only pertains to the Analog Discovery Studio.
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.
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.
When using the Breadboard Canvas that is included with the Analog Discovery Studio, a piece of foam is under the Breadboard Canvas covering the contacts between the Analog Discovery Studio and the Breadboard Canvas. Remove this foam to allow the Analog Discovery Studio to interact with Breadboard Canvas and then place the Breadboard 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 USB Type B cable that is included with the Analog Discovery Studio. 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.
Four power switches are in the top right hand corner of the Breadboard Canvas to enable each of the 4 different power supplies: +3.3V, +5.0, both ±12.0V, and both of the ± variable voltages. The variable voltage ranges are limited to +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.
Three separate user LEDS (red, yellow, and green) can be enabled by providing between a 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.
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 viewed through the respective outputs labeled BTN1 and BTN2.
The 5.0V power switch must be enabled for the buttons to work.
Two user IO switches labeled SW1 and SW 2 are present to the left of two user buttons. The outputs of the switches can viewed 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
Connect connect the 2×10 flywire set that is included with the Analog Discovery Studio to the fitting slot on the ADS. The flywires are notched so they only fit one way.
Connect the 2 two-wire flywires to each of the WaveGen out connections on the Analog Discovery Studio.
Connect the WaveGen Out 1 to the LED RED input and connect WaveGen Out 2 to the LED GRN input. Connect the Trig 1 input on the Analog Discovery Studio to the BTN1 output and the Trig 2 input to BTN2 output.
Open the WaveForms software and open the WaveForm Generator tool. Additional details and resources on how to do this can be found in the WaveForm Generator guide. Enable both Channels on the WaveForm Generator.
When button 1 and button 2 are pressed, the red and green LEDs will flash at different rates as set by the frequency.
