The USB CDC driver for Atmel SAM ARM microcontrollers allows a USB microcontroller that is running the SAM-BA software to be configured as a virtual COM port on a PC.
This allows user software to be loaded to the microcontroller via a USB cable using the SAM-BA PC application software.
The article on Installing the SAM-BA USB CDC Driver for Atmel ARM Microcontroller in Windows shows how to install and test the driver.
Terminal emulator software is used to communicate with the embedded SAM-BA software on the microcontroller and request the SAM-BA software version number. This is done to test that the driver and connections are working properly.
If you have found that some websites do not display correctly when using the Midori browser on your Raspberry PI / Raspbian operating system, the problem could be that the fonts used by the browser do not exactly match the fonts used by the website designer.
The problem can quickly be fixed by installing some extra fonts as this article explains: Getting Websites to Display Correctly in Midori on Raspbian for the Raspberry PI
This article on ten things to do after buying a Raspberry PI shows how to install the Raspbian operating system, change settings, play a video, clone your SD card and more.
The ten things to do are the following:
- Install the Raspbian Operating System — you need and operating system to use your Raspberry PI and Raspbian is the “standard” OS for the PI board.
- Set Language and Keyboard — the default settings for the Raspberry PI are for the UK, if you are located anywhere else, you will probably need to change these settings.
- Setup Timezone — if you are not located in the UK, you will need to change the timezone. The Raspberry PI gets the current time from the Internet.
- Start the Graphical Desktop — start and explore the graphical desktop that is installed with Raspbian.
- Change Screen Viewing Area — there is usually a black border around the HDMI screen after installing Raspbian – remove the border to make full use of the screen area.
- Update System Software — make sure that the Raspbian operating system and installed applications are updated to the latest versions.
- Login Automatically — if you want to automatically run an embedded application on the Raspberry PI at switch on, you will first need Raspbian to boot up without the need for you to log in.
- Play a Video — the Raspberry PI is capable of playing video up to full 1080p HD resolution.
- Automatically Run an Application — if you want to use your Raspberry PI for a dedicated purpose, you will need to run your application software at switch on.
- Clone Your SD Card — after installing an operating system, configuring it and then developing your own custom application, it is a good idea to back up your work by cloning your Raspberry PI SD card. This will also enable you to make multiple copies of your project.
