Blynk and Nucleo with STM32duino framework

Hi all,
I’ve created a small blynk app that works with an arduino UNO. I would like to perform the same thing with a NUCLEO STM32L476 hardware (that uses the STM32Duino framework which exposes the exact arduino API). This board is much more powerful for the half-price. But how can I manage this board from the phone app ? How can I use the digital PINs that are above #13 ? For instance, push button is D23, so which board should I use to set digital PIN #23 for an arduino-like board in the app?
By the way, how can I add a brand new board template in app ?

Thank you

Is there any reason (other than speed and cost) that you wat to use this particular board?

Most people tend to migrate to a NodeMCU type of device once they get tired of the Arduino Uno and it’s much easier to support for these types of board.


Thank you for your quick reply.
Obviously, NodeMCU type tends to be a “de facto” standard for this application.
I manage a educational technology association and our partner provides a lot of Nucleo boards. So, naturally, it might be interesting to use them as “my first connected thing” with USB connection to a PC.

BTW, I’m wondering that if it is easy to add a new type of board in the device list on the app.
The Nucleo board provides a lot IOs, flash memory and it’s really similar to an Arduino UNO or NodeMCU from an Arduino API point of view. I found in the device list a “generic board”. Is it a good start to use a Nucleo ?
FYI, setting a LED to on is exactly the same sketch on Nucleo and Arduino.
Finally, Blynk offers a way to connect over USB that is a good way for us to use the same hardware as we’re using for other experimentation. But the bottleneck is on the app side.
Thank you all for your feedback

Hi there I’m new to blynk. But support for the STM32L476 and later Stm32l552 would be nice.
To extend the possibilities it would be nice to have more boards supported, when there is any information to help extend would be great.
After using Arduino types for several years I stepped to the larger, faster and more memory STM32L4 Nucleo-64 and L5 Nucleo-144 boards.

Forum member @khoih as done quite a bit of work on supporting thse boars recently. Take a look at his posts and you’ll no doubt find them useful…

As far as the app side of things is concerned, you’ll need to select Generic Board and you may need to use virtual pins rather than digital pins (which most advanced users do anyway, even with boards that are fully supported).
