![]() ![]() ![]() The Freedom KITs from NXP make my life very easy when I want to hack together some hardware examples for teaching. The teaching/learning philosophy of Scratch is awesome, but I want to teach using real world examples. I installed it in Ubuntu with the command “sudo apt install scratch”. I realized they have an offline version of scratch 2.0 which is great. In my quest to look for better introduction to computer programming training methods for the young groups, I landed on the MIT Scratch on the web. Posted in Embedded systems | Tagged Scratch | Leave a response Install scratch in /opt which is the default install location.Navigate to the location of your scratch download and select the scratch.air file.Download the Adobe AIR shell script file and install it by running the commands:.To install Scratch 2 on Ubuntu, run the following commands from your terminal. For this reason, I decided on Scratch 2 Offline Editor. sb files so I could not view the projects I had done online on my offline editor. It was great, until I realized that there was a difference between that editor and the online one. At first, I installed it in Ubuntu using the command “sudo apt install scratch”. I recently came across Scratch, an ingenious free programming language and online community where you can create your own interactive stories, games, and animations by MIT.

GNU ARM Eclipse Plugins by Liviu Ionescu is another success story for me. USBDM is one debug software that I loved to learn about. Stuff like peripheral register views were not available in eclipse when I started writing tutorials on how to install vanilla eclipse, then add hardware debug plugins. It has also allowed GUI tools developers add more features to their software suites to better help the developer debug hardware. It is, I believe the reason why Mbed, FreeRTOS and other operating systems have been ported to ARM microcontrollers and support for different families of these microcontrollers added so fast. This has kind of standardized software interfaces make porting code to new microcontrollers easier and encourage code re-use. It has been extended beyond the core to interfaces like CMSIS-DAP debug and later to others including Drivers, DSP, RTOS-API, Software Packs and SVDs which are System View Descriptions for peripherals e.t.c. Its implementation provides a standard interface for the core of the micro-controller, the ARM CPU and peripherals. The tools provided by manufacturer as an IDE provide you with a way to create a new project for a specific micro-controller, putting together the MCU header file, the linker script, the startup script and potentially the peripheral registers declarations or drivers.įor ARM ®, there is of course the Cortex ® Microcontroller Software Interface Standard (CMSIS) that helps abstract hardware access. Once you have those in place and test them roughly, you want to write application code. The main focus at the beginning of writing embedded software is figuring out the memory mapping, startup and hardware drivers. There are situations where what you need is an API of all the low level register access definitions and functions/Macros or whatever you want to call them, routines even… and you want to write your own code the best way you know how, whether using an infinite while loop in main or using an embedded operating system like FreeRTOS. Add the –force-overwrite option to the dpkg command by editing line 35 in the file, save and close geditĭpkg -i -force-depends -force-overwrite mcuxpressoide-10.0.0_344.x86_64.deb.Get into the install folder and open the install script in a text editor If the installation succeeded, there is no need to bother much.It will fail but leave the extracted folder with files behind for the next stepĬd Downloads & sudo. press CTL+ALT+T to open a terminal, change to the directory where the file is and run the binary file with –keep option.Download the installation file from NXP’s IDE page.I found the answer in the support forums and here are the steps to follow: I read a blogpost on mcuoneclipse about MCUXpresso installation and I downloaded the installation files for MCUXpresso from NXP and headed for the terminal to install, only there was an error about some P&E probe udev permissions file failing to be overwritten during the installation process. ![]()
