-Processor cores are individual processing units within the board's main processing unit (do not confuse a processor core with an [Arduino core](https://www.arduino.cc/en/guide/cores)). These cores are responsible for executing instructions at a particular clock speed. The on-board  Arm Cortex processor comes with two cores (Cortex® M7 and M4), with slightly different architectures and clock speeds. The M7 runs at 480 MHz and the architecture is designed to separate Instruction and Data buses to optimize CPU latency. The M4 runs at 240 MHz and the architecture supports the ART™ accelerator (a block that speeds up instruction fetching accesses of the Cortex-M4 core to the D1-domain internal memories). The higher clock rate of the M7 makes it suitable to handle complex processing tasks such as data storage, debugging or handling input/output peripherals at a higher efficiency compared to the M4. The dual core processor of the Portenta H7 sets it apart from other single core Arduino boards, by allowing true multitasking, faster data processing capabilities, enhanced processing power and application partitioning.

We know you are eager to try out your new board but before you can start using the Portenta H7 to run Arduino sketches you need to configure your computer and the Arduino IDE.

 One of the benefits of the Portenta H7 is that it supports different types of software cores. A core is the software API for a particular set of processors. It is the API that provides functions such as digitalRead(), analogWrite(), millis() etc. which directly operate on the hardware.

 ## Portenta and The Arduino Core
-The Portenta H7 is equipped with two Arm Cortex ST processors (Cortex-M4 and Cortex-M7) which run the Mbed OS.  Mbed OS is an embedded real time operating system (RTOS) designed specifically for microcontrollers to run IoT applications on low power. A real-time operating system is an operating system designed to run real-time applications that process data as it comes in, typically without buffer delays. [Here you can read more about real time operating systems](https://www.ni.com/en-us/innovations/white-papers/07/what-is-a-real-time-operating-system--rtos--.html).

-The Arduino core for the Portenta H7 sits on top of the Mbed OS and allows to develop applications using Mbed OS APIs which handle for example storage, connectivity, security and other hardware interfacing. [Here you can read more about the Mbed OS APIs](https://os.mbed.com/docs/mbed-os/v5.15/apis/index.html). However, taking advantage of the Arm® Mbed™ real time operating system's powerful features can be a complicated process. Therefore we simplified that process by allowing you to run Arduino sketches on top of it.

-This step is the same for both the classic IDE and the Pro IDE. Open the board manager and search for "portenta".  Find the Arduino mbed-enabled Boards library and click on "Install" to install the latest version of the mbed core (1.2.3 at the time of writing this tutorial).

 ### 3. Uploading the Classic Blink Sketch
 Let's program the Portenta with the classic blink example to check if the connection to the board works. There are two ways to do that:
 
--   In the classic Arduino IDE open the blink example by clicking the menu entry **File > Examples > 01.Basics > Blink**. You need to swap LOW and HIGH pin values as the built-in LED on Portenta is turned on by pulling it LOW.
--   By downloading the 'Arduino_Pro_Tutorials' library and opening the pre-made sketch under **File > Examples > Arduino_Pro_Tutorials > Setting Up Portenta H7 For Arduino > Blink** 
--   In the Arduino Pro IDE Copy and paste the following code into a new sketch in your IDE.

 ### 4. Upload the Blink Sketch 
-Now it's time to upload the sketch and see if the LED will start to blink. Make sure you select Arduino Portenta H7 (M7 core) as the board and the port to which the Portenta H7 is connected. If the Portenta H7 doesn't show up in the list of ports, go back to step 5 and make sure that the drivers are installed correctly. Once selected click Upload. Once uploaded the built-in LED should start blinking with an interval of 1 second.
