STMicroelectronics B-L475E-IOT01A Discovery Kit for IoT Node

STMicroelectronics B-L475E-IOT01A Discovery Kit for IoT Node allows for development of applications with direct connection to cloud servers.

The Discovery kit enables a wide diversity of applications by exploiting low-power communication, multiway sensing and ARM® Cortex® -M4 core-based STM32L4 Series features.

The support for Arduino Uno V3 and PMOD connectivity provides unlimited expansion capabilities with a large choice of specialized add-on boards.

Board Features :

* Ultra-low-power STM32L4 + MCU based

* on-board ST-LINK/V2-1 debugger/programmer with USB re-enumeration capability.

* Bluetooth 4.1 module

* 802.11 b/g/n compliant Wi-Fi module

* Dynamic NFC tag

* 2 digital ommnidirectional microphones

* Humidity and tempurature sensor

*3-axis magnetometer

*3D accelerometer and 3D gyroscope

* Time-of-flight and gesture-detection sensor

*Digital output barometer

Applications :

** the UART I/F on B-L475E-IOT01A (IoT Node)

Create a new project using STM32CubeMX.

Select B-L475E-IOT01A board

In Pinout view tab, check that USART1 mode is configured to Asynchronous, PA9 is connected to USART2_TX and PB7 is connected to USART2_RX.

Switch to the Project Manager tab and Click on Generate Code .

Insert the following lines

After the compilation and runing the project , open TeraTerm and Configure the console baud rate and data bits length. The COM Port name may differ on your PC.
