I'm using
Windows 11 64bit
Arduino IDE 2.0.0rc6
Sparkfun Arduino Red board ftdi
SparkFun Qwiic Shield
Qwiic GRID-Eye Infrared Array
WS2812B 8x8 led
However when testing example number 1 serial visualizer it uploads but doesn't display dispite checking boad matching sketch, it doesn't output anything just shows send message to arduino which doesn't do anything I don't get a visual appear on my computer like described in guided, do i need to add values to example or should it work straight out of the box?
I've tryed skipping to the demo code below to have the full working version as demonstraighted but thought maybe I need to follow the other steps first.
Whilst skipping to the last demo link which takes me to github code I upload the sketch and the lights turn on all red but sensor seems to do nothing?
Is it faulty sensor, do i need to input my own values on examples.
I'm new to coding and have been reading many forum messages and lost on why I actually need.
What I wanted grideye to do is light up leds to match temperature so if person walks but its red, if I cold object appears its blue if normal temp (so I guess a tollerance would need to be set) have leds off. It might be easier setting this up on an oled or tft screen to display thermal image, but i was trying to make a crude led version as demo showed but no luck and i'm lost.
If links are not allowed please let me know i'm new and just need help.
I tried the led using adafruit string and it works, but everything I try with sparkfun grideye library nothing works, sketch uploads and leds light up all red so at first i thought it was cold tollerance to high changed it but it made no difference. I suppose I buy another grid eye and try again.
I don't think it's a driver issue although it is weird that red board has to be setup as uno but needs ftdi drivers, but my computer seems to have detected ok.
Although it keeps appearing with a yellow triangle and ! says no board and comes back on arduino uno on com 5, but in the left hand it always displays as still connected.
It always uploads no problem but seems programme IDE is a bit buggy.
Do you know of a really simple way to engage with grideye to display back on same computer screen? I would have thought it should be the examples?
I don't have your boards, but bought the Panasonic evaluation board - the only "problem" I had was that the device isn't 5V tolerant, but I used a Due for speed and memory anyway.
I'd take a close look at the I2C error messages
However, I gave up on the GridEye when I got the Melexis MLX90640 - similar price, twelve times as many pixels.
So this serial monitor should be what prints out in Arduino IDE, i've checked driver on device manager and its set for 9600 bits, so have changed programe to match boad sketch and right hand drop down to match and still nothing.
This is what I see attached.#
I might looked at that other sensor wish i had spotted it before, it does sound better.
I wanted to start with visual dection and then add like a buzzer for sound alert.
I have so many project ideas but this is my first attempt.
Add a print statement to setup(), so that you know that the program starts successfully.
void setup() {
// Start your preferred I2C object
Wire.begin();
// Library assumes "Wire" for I2C but you can pass something else with begin() if you like
grideye.begin();
// Pour a bowl of serial
Serial.begin(9600); //better to use 115200 for both
while(!Serial); //wait for connection to be established
Serial.println("Grid eye demo started");
}
Ok this is great, thankyou for everyone on this topic, really appreicate it.
If I can get this going I have so many ideas on other projects I'd love to build and make more compact easier and open.
Thanks so much all, i'm signing off for now but keep posting ideas anything you can think of i'll look at next weekend and keep you all posted on how it goes as no doubt someone else will stumble across maybe years down the line like myself
Hello,
So tried another IDE whilst is does seem to work on win 11 and connections seem more stable and actually opens a serial montor the serial montor returns nothing no but just continously scrolls. when I wave my hand infront of it no numbers are populated.
