Hello to everyone, I want to share with you this video about the Installation of sample code on UDOO KEY. I hope it helps.

If you agree we can collect all the video about the UDOO KEY in this thread.

Thanks!

Getting Rusty with the Udoo Key

invalid@example.com (DrewTChrist) — Fri, 27 Jun 2025 11:05:44 +0000

Hello everyone,

I've been working on a repository of small programs for the Udoo Key written in Rust. I thought I'd share them here for everyone to take a look at. Right now there is a blinky for each individual chip. There is also an example that uses the serial connection to coordinate blinks between the chips with interrupts.

The next program I have is a socket client on the ESP32 and a Chip8 interpreter on the RP2040. The ESP32 will read a Chip8 rom from a socket server and then pass...

Arduino with UDOO KEY

invalid@example.com (leo64) — Tue, 10 Jun 2025 06:16:39 +0000

The campaign page says you can use the Arduino ide but all I can see in the documentation is using linux or for the esp32 using esspresifs tool. The lack of documentation and this whole project is a joke. Has anyone managed to actually gotten arudino to work with this board?

How can I access and read microphone input using Arduino?

invalid@example.com (mrk) — Thu, 15 May 2025 06:37:34 +0000

I’m working on a project that requires capturing audio data through a microphone connected to an Arduino board. What’s the best way to interface a microphone with Arduino? Are there specific microphone modules or sensors I should use? Also, how can I read and interpret the sound signals using Arduino’s analog or digital inputs?

Has anyone been able to work with the Arducam 2MP that you could get with the kickstart Pro pledge?

I try mostly every examples and tutorial.
I defined the pin like below, but I can initialize the SPI (failed at Check SPI bus in setup)

Code:

const char* ssid = "ssdi";
const char* password = "password";

I2S and I2C On Pro What addresses/Pins

invalid@example.com (digiital) — Thu, 25 Jul 2024 11:37:37 +0000

The lack of documentation on the sensors is pretty disappointing.

I think I found the i2c address for the "IMU motion sensor" . I thought there was a temperature sensor for the esp32 but seems like it's only the pi builtin.

For the Microphone, what pins is it connected to on the esp32, I'm assuming it's not connected to the pi at all even with the jumpers.

I'm doing a WHOLE LOT OF Googling to try and figure out the details and trying this and that. When the details should be clearly...

Interface cable to go between the UDOO key ESP32 10 pin header to the Grove Shield board

invalid@example.com (AD1) — Wed, 20 Mar 2024 03:03:55 +0000

Got my kit in the US a few weeks ago. Just starting to figure it out since I am a rookie to micro programming.
Question: Is there an interface cable to go between the UDOO key ESP32 10 pin header to the Grove Shield board? Question mark in the attached photo
Again total rookie here working.

Voice Detection on ESP-32

I've been working on making an offline voice timer using the ESP32 for voice recognition and the RP2040 for everything else (a little display, sounds, ...). I've hit a bit of a wall with the speech recognition portion and I was wondering if anyone had any suggestions or had a better performing method for speech detection.

Installing sample code (using UBUNU) on UDOO KEY!

I am trying to install the sample code on my UDOO X86 running UBUNTU 18.04.1.
When I get to here "git clone --recursive https://github.com/espressif/esp-idf.git -b 4.4.1", I get "fatal: the remote branch 4.4.1 not found in upstream origin"
I can't find any information that can help me go past this command. Anybody like to provide a way forward?

Read ICM-20948 IMU sensor via I2C

Hello,

I have received my UDOO KEY, I try to read ICM-20948 sensor via I2C form both microcontroller (RP and XX) with Micropython.
When I try to query the sensor on the I2C bus by requesting the device ID, I always get an unexpected value (see attached image).

Failed to get PID of a device on COMx

invalid@example.com (cyberlmt) — Fri, 01 Sep 2023 15:37:22 +0000

I installed esp-idf on Windows 10. Version 4.4.1 of the tools was not available in the Git repository to I installed the default version, which installed successfully. I then attempted to flash the blinker program. It failed. The error message is "Failed to get PID of a device on com12, using standard reset sequence." I ran esptool.py to troubleshoot the USB serial com connection. The results were:

Retrieve MPU6500 imu-sensor data with Arduino

invalid@example.com (Opi-Van-Kristovi) — Fri, 11 Aug 2023 13:51:52 +0000

It took me a while to figure out how to get readings from the on-board IMU sensor, so I'll share the code I used, made with the fastIMU Library in Arduino IDE, which can easily be found and installed in the Library Manager:
It does a self calibration on startup (can be disabled) and proceeds to print out al its values to the serial monitor every 150ms.
Code for ESP32:

Code:

#include "FastIMU.h"
#include 

#define IMU_ADDRESS 0x69    //Change to the address of the IMU
#define...

Serial connection between MPUs

invalid@example.com (JMuller) — Fri, 11 Aug 2023 09:51:05 +0000

I wanted to use standard serial communication to send a message from the ESP32
to the 2040 to control the on-board LED.
Several problems with UART ports and setup were resolved. I found that I cound not
test the signals between the two devices since they are not exposed in hardware (
IO 0 & 1 on the 2040 are not connected to the output pins like on the standard 2040 and
on the ESP32 IO 19 & 22 connections are not provided).

I also found the Udoo Key's MCU connections page...

You want social media coverage? You'll now get it

After the last "update" on Kickstarter it is obvious that this is a scam and you try to let us wait for the product with new excuses every few weeks in updates. Your shipment schedules do not add up and the number of items shipped a day is ridiculous.

I will now start warning about this company in social media and the press so others doe not make the mistake to give you money.
