This is a follow-up article of my earlier project presented in “FatFS, MinIni, Shell and FreeRTOS for the NXP K22FN512“. I wanted to extend it with a USB MSD (memory stick) device: The USB storage device gets automatically mounted, and depending on a configuration (.ini) file on the memory device I can perform various actions, for example automatically copy data from the SD card to the USB device. For example the system logs data, and to get the data I insert the memory stick, it copies the data on it and automatically unmounts it, and I can remove the memory stick.
I’m using the NXP Kinetis K22FN512 in many projects, either with the FRDM-K22F or on the tinyK22: with 120 MHz, 512 KByte FLASH and 128 KByte it has plenty of horsepower for many projects. The other positive thing is that it is supported by the NXP MCUXpresso IDE and SDK. I have now created an example which can be used as base for your own project, featuring FreeRTOS, FatFS, MinIni and a command line shell.
I’m pleased to announce that a new release of the McuOnEclipse components is available in SourceForge. In this release more ARM Cortex devices/vendors are supported with different SDKs, plus it comes with several FreeRTOS enhancements for debugging highly optimized code.
I want to make some noise with this post!!! This tutorial is about adding music and sound capabilities to the Freescale Freedom board, and to have a lot of fun with it :-). I need this ability for a larger project working on for a while. But I thought I share that sub-part how to play sound files. So with this tutorial I can turn my Freescale Freedom board into a music or sound player :-). And adding sounds is a cool way for any project, and as the music is stored on an SD card it fits easily hours of music or sounds.

I have received several requests to post a quick note when there is a new release (16-Nov-2014) of the McuOnEclipse components on SourceForge (see “McuOnEclipse Releases on SourceForge“). I have published today a new release, and with following major improvements:
USB support for Kinetis KL24Z
FatFs now features the latest Elm-Chan v0.10c release
Backspace support in Shell
Configuration item in FreeRTOS for Percepio Trace Hooks
I admit: I’m sometimes a lazy person. In my projects, I only needed one ‘disk drive’ with the FatFS Processor Expert component: either a SD card or a USB MSD drive. But a reader of this blog wanted to use FatFS with multiple drives: using it with an SD card and a USB MSD drive. And actually FatFS does support this, I just had no need for it, thus I did not add anything special for it. But that reader let me think that I better add Multi-Drive support. Even if I do not need it now, that could be very handy in the future 🙂
