How to Use the Blynk App on IoT Board(Nucleo)





Introduction: How to Use the Blynk App on IoT Board(Nucleo)

I know STMicroelectronics Nucleo platform for IoT. Recently W5500 Ethernet shield will be announced by WIZnet.

So I implemented a firmware of Nucleo board by Ethernet SW modification because I can handle a source code easily. You can know the status of equipment even if it is so far. Please refer to the following step.

Step 1: Prepare Materials

Please refer to the following.

1. Nucleo board

2. W5500 Ethernet shield

3. Easy Module shield

4. LAN cable

5. USB cable

Step 2: Hardware Connection

Please connect an LAN cable and USB cable

You can get more HW info by the following site.

Step 3: Prepare Development Environment

Step 4: Introduction of W5500 Chip

Step 5: Introduction of Blynk Platform

Step 6: Software

I uploaded CoIDE project.

You can download this project file. And then import project into CoIDE. After compile, you can run control operation through Blynk platform.

Step 7: How to Run : Test Result

You cannot control D10, D11, D12, D13 pins because those are used for Ethernet SPI.

1. To unzip Blynk_STM32F411_CoIDE project

2. To open Blynk_STM32F411_CoIDE project

3. To downaload the Blynk App into Smartphone.

4. To login Blynk App.

5. To create a new progject on App.

6. To check "Auth Token" by Email.

7. To modify "Auth Token", Server IP, MAC address, IP address.

8. To build/rebuild and download to a target.

9. To add Widget Box and modify an example project.

10. To check the result of device control.

Thank you for your attention.
