Run the following commands in terminal and provide password whenever prompted for. This setup has been tested on macOS High Sierra.
#Arduino arm cortex upgrade
Note that Explore M3 acts as Device Firmware Upgrade (DFU) and virtual COM port with the same USB interface. You may be required to give permissions to use virtual com port. Give appropriate permissions when running the install.sh and other files. install.h (change the file permission if required). rulesĮcho "Adding current user to dialout group"Įcho "Couldn't copy to /etc/udev/rules.d/ you probably have to run this script as root? Or your distribution of Linux doesn't include udev try running the IDE itself as root." #!/bin/sh if sudo thenĮcho "Copying Explore M3-specific udev rules." The board shows up as unknown device in device manager. The RGB LED turns green indicating USB Boot mode. To upload a new program to Explore M3, put the board in programming mode by holding down the USB Boot switch, press and release the reset switch and then release the USB Boot switch. #Arduino arm cortex driver
This driver is used for programming the Explore M3.
Installing the Device Firmware Upgrade(DFU) Driver. Verify successful installation in the device manager. #Arduino arm cortex install
Install the CDC driver using the Zidag utility this time.Go to AppData\Local\Arduino15\packages\ExploreM3\hardware\Explore-M3\1.0.0\tools\win and run the Zadig utility.Go to run window (Windows+R), type %appdata% and click ok.Connect the board to system, the COM port will appear as shown.
#Arduino arm cortex serial
The virtual COM code on the Arduino resides with every sketch that uses the Serial Class.
Install Virtual COM driver This driver makes the same USB interface appear as virtual com port. Now the Explore-M3 board will appear in the board list. \AppData\Local\Arduino15\staging\packages. If you encounter CRC mismatch Error, delete Explore M3 Arduino installation files from below mentioned paths and retry installation. 
Once the installation has completed, an Arduino-blue INSTALLED will appear next to the entry.
Installation may take few minutes depending on the internet speed.
This will install the Explore-M3 board and the arm-none-eabi-gcc tool chain. Click on the board entry and hit install. Scroll down and look for Explore-M3(32-bits ARM Cortex-M3) board. Open the Board Manager from Tools->Board->Boards Manager. Open the Arduino IDE and go to File->Preferences and paste the below json URL into the Additional Board Manager URLs text box and hit OK. Older versions of the Arduino IDE are not supported. Download and install the Arduino IDE (1.6.12 ). If you can do this correctly, you should have the skills to use hardware registers to initiate a task, read status bits, and read a result.(This Step is common for all operating systems) You can easily figure out how this is done by simply reading the source code for analogRead but splitting it into 3 parts. You can have the code do other stuff if the ADC is busy. So for homework, turn analogRead into three functions: void analogReadStart(pin), bool analogReadIsBusy(void), and int analogReadResult(void). 
That waiting time is wasted time, you can reuse that time to do other calculations. Basically, every time you call analogRead, it is setting up the ADC, starting the ADC, and waiting for the ADC to finish conversion, and then returning the value. Then I think it would be wise to learn "non blocking" coding. Port manipulation is probably the easiest. You need to first know what information exists in the datasheet, especially the "register description" sections, and read every single word
