Differences between Bluno M3 and Arduino

Overview The Bluno M3 is different to previous Bluno boards as it is based on a 32bit ARM Cortex-M3 core architecture. A regular Arduino is based on an 8bit AVR core. Due to these differences, machine commands are also different. Arduino IDE uses avr-gcc, whilst Bluno M3 uses armnone-eabi-gcc.

Hardware Ports
• ADC Pins marked with "Ax" e.g. A0, A6, A10 can be used as Analog input ports
• Uart 5 Serial Ports in all Bluetooth and RX1/TX1 use

Serial1
• SWD STM32 debug port, you can use debug hardware based on STM32 on these pins
• GPIO All pins can be used as digital I/O, including analog pins

Language and Library Software Differences
• ADC Bluno M3 provides two kinds of ADC mode one is compatible with Arduino, the other is Bluno M3's unique way adcMode and adcRead , which makes it more powerful. Refer to Bluno M3 Bluno M3 Reference manual ADC Application.
• PWM Bluno M3 provides two kinds of PWM mode, one is compatible with Arduino, the other is Bluno M3's unique way pwmMode and pwmWrite ,which makes it more powerful. Please refer to Bluno M3 Bluno M3 Reference manual PWM Application.
• UART There are 5 UARTs on the board. UART1 is corresponds to the Board RX1 and TX1, and it is also connected with the Bluetooth communicating port.

QuickStart

In this section, we will guide you how to use Bluno M3 step by step.

Setup Software Development Environment

Download IDE and Bluno M3 Driver Download Bluno M3 Arduino IDE Arduino IDE M3 Version from OneDrive folder%2cpdf

This is a custom version based on Arduino IDE where we have redefined the interface functions. Please note that because of this, other versions are not compatible with Bluno M3.

Install Software
• Download Arduino IDE Bluno M3 version and extract the files to your computer.
• Configure Environment Variables

Open Control Panel > System and Security > System > Advanced System Settings > Environment Variables Select PATH, and click Edit... button

Copy the Arduino IDE Bluno M3 Version directory path you downloaded before in to PATH. For example Click OK.

Note If there are a lot of directories in PATH, you can use ";" semicolon to split them.

Install Bluno M3 Driver

Connect Bluno M3 to your PC's USB port, open Hardware Devices and select the Driver folder. Note The Driver folder is located in your Arduino IDE Bluno M3 version hardware drivers folder. e.g.

Blink an LED
1 Open Arduino IDE Bluno M3 Version 2 Select "Bluno M3" and COM port
