SparkFun Edge

Development Boards
1

I bought an edge and I’m trying to read the signals it sends to the serial port.

I havn’t yet programming it!

In this document:

https://learn.sparkfun.com/tutorials/pr … rduino/all

I read:

…

Micro Speech

From the micro_speech folder in your TensorFlow_AIOT2019-master folder, open the file micro_speech.ino. Full disclosure - this is the sketch that comes pre-loaded on your SparkFun Edge Board, so you should already see the blue LED blinking. If you open the Serial Monitor of your Arduino IDE, saying “Yes” will return something like “Heard yes (203) @4032ms,” accompanied by a single blink of the yellow onboard LED; saying “No” will return a statement similar to “Heard no (209) @7936ms,” along with a blink of the red onboard LED. Any other word or statement that the mics pick up will return “Heard unknown (212) @50304ms.”

…

But, I don’t receive nothing from the serial.

When I send a string to SparkFun Serial Basic by Arduino Serial Monitor, the TXO led blink, so the serial connection is ok!

Why?

Does anyone have a working Edge?

Thanks

Make sure you are selecting the proper port for the board and you are using the right baudrate. In the drop down menu, at the bottom of the window of the Serial Monitor, select 9600 baud.

madalosso - are you able to see the LEDs on the board (RED, BLUE, GREEN, YELLOW) blinking?

The Blue LED should blink rapidly to let you know that the code is running. If you don’t see that I would recommend re-uploading the executable. ([Google CodeLabs (Careful - a little outdated but the process is generally correct) or [SparkFun’s Tutorial)

If you do see the Blue led then:

Can you see the Yellow LED light up when you say ‘Yes?’

Can you see the Red LED light up when you say ‘No?’

If you don’t see those happening then the board is not recognizing your voice. This is not terribly surprising b/c the models are relatively small. My best hint is to do your best imitation of a hip Brit software guy when speaking.

If you do see the lights then you are getting matches - and so there should be serial output at 9600 baud. Try adjusting your baud rate in the Arduino serial monitor as suggested by santa impersonator.](Programming the SparkFun Edge with Arduino - SparkFun Learn)](AI Speech Recognition with TensorFlow Lite for Microcontrollers and SparkFun Edge  |  Google Codelabs)

My board blinks blue, no other colours when speaking. Other colors when clicking the reset (red and orange flash). If 14 and reset, no leds.

Starting to think this board is garbage.
