Ardi-32_Software

Ardi-32 is the ultimate Arduino Uno alternative packed with powerful specs and exciting features in the Arduino Uno form factor. Ardi-32 is powered by the latest ESP32-S3-WROOM-1. Built-in Wi-Fi and Bluetooth connectivity for Ardi-32 boards make them ideal for IoT projects or projects requiring wireless communication. This github provides getting started guide and other working details for Ardi-32

Ardi-32 Compatible Shields are Relay, RFID, Display and UHF which you can use to add more functionality into projects.

Features:

• Powered by powerful ESP32-S3-WROOM-1 module with inbuild WiFi and BLE support.
• Arduino UNO Form factor, so you can connect 3.3V compatible Arduino shields
• SD card slot for storage and data transfer
• The facility of Type C USB interface for programming and to power the board
• Boot and Reset buttons are available to operate in various modes.
• Multifunction GPIO breakout supporting general I/O, UART, I2C, SPI, ADC & PWM functions.
• Multi-tune Buzzer to add audio alert into the project
• Multi-platform support like Arduino IDE, Espressif IDF, and MicroPython/CircuitPython
• Comes with HID support, so the device can simulate a mouse or keyboard

Specifications:

• ESP32-S3 series of SoCs having Xtensa® dual-core 32-bit LX7 microprocessor
• 4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE)
• Flash up to 16 MB, PSRAM up to 8 MB
• Board Supply 5V and GPIO pins operating voltage 3.3V
• 22 Multipurpose GPIOs breakout in Arduino style for easy peripheral and shield interfacing
• I2C, SPI, and UART communications protocol support
• Cross-platform development and multiple programming language support

Note: When SD card not connected, then above related pins can be used for normal GPIO operations.

1. Configure and Setup Development Environment

• Download Arduino IDE from official site and install into your system. We have use Arduino IDE 1.8.19

• Once installation done will add ESP32 S3 board support into IDE, for this first you need to add below link into preference: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

  Select File > Preference, and add link as show in below image,

• Now will install ESP32 based boards as shown in below image,

  

• Once done, keeping default settings select the ESP32S3 Dev Module with suitable com port (may be different in your case) as shown below,

  

CP2102 Driver installation

• In case you don't see com port then you will have to install CP2102 driver from Link. Download and install as per your operating system.

  • check below one recommended for windows user

    

  • Once successfully installed then it appears as shown in below image

    

2. Testing First Code

• At this step you are all set to test codes, for easy getting started we have provided various demo example codes in github which you can download and try.

• Open one example code in Arduino and make sure you have selected correct board with suitable com port, click on upload button to transfer code on Ardi-32.

• Checkout other examples below and build your own custom program codes using those references.

3. Installing Libraries

• Download library zip file provided here in github.

• Extract and copy files inside Document > Arduino > Libraries folder. Make sure to restart Arduino IDE whenever you update or add any libraries.

  

Example Codes

In example folder you will find demo examples to try out on ArdiFi

• Buzzer : code to test onboard Buzzer
• SD card : code to test onboard micro SD card interfacing

Also, sample codes are available for Ardi32 shields

• Ardi Relay shield Code : code test switching of relays in sequence, for more details refer Ardi-Relay Shield
• Ardi RFID shield Code : code to test RFID module scan and switching of Relay, for more details refer Ardi-RFID Shield
• Ardi Display shield Code : testing of display and programmable buttons, for this example to try you need to install libraries provided in github. Step 3 shows how to install libraries. For more details refer Ardi-Display Shield
• Ardi UHF shield Code : testing onboard UHF module, for more details refer Ardi-UHF Shield

Using this sample code as a guide, you can modify, build, and share codes!!
