Fresh hacks every day
This is a device which [Limpkin] has been developing at his day job. It’s a high-speed testing interface for use with Physics experiments. We find it interesting because it uses an ARM microcontroller to implement CDC and MSD over USB.
The design is in two parts to make it work in a rack-mount situation. That big white connector allows … Read the rest
I finally set aside some time for one of my own projects. I have been playing around with ARM microcontrollers a lot lately and wanted to try out my GLCD display that uses the KS0108 protocol. It’s 5V but I had heard that some of these displays will work with 3.3V TTL. But the datasheet tells me otherwise. I tried … Read the rest
We’ve tried building our own ARM cross compiler on a Linux box and it’s no picnic. Luckily there is a free cross compiling toolchain available through Mentor Graphics (formerly called Code Sourcery G++). But those looking to develop on a Mac aren’t so lucky. There is help via a script, and [Michael] wrote a guide detailing how to use crosstool-ng … Read the rest
[Andrzej Surowiec] liked the functionality of the mass storage bootloader available on some NXP LPC development boards. His latest project was to write a mass storage bootloader for the Stellaris Launchpad. It allows you to flash your compiled firmware to the chip simply by mounting the board as a USB storage device and copying over the binary file. The … Read the rest
We’re partial to using gedit and a makefile for our AVR projects. But for the most part we don’t a debugger with those smaller chips. Now that we’re getting going with ARM processors we use debugging all the time and Eclipse is a great way to combine code writing, compiling, and debugging in one place. Sure, we could use one … Read the rest
There are several things that we really like about the TI Stellaris. We think the peripheral library — called Stellarisware — has a pretty intuitive API that makes it easy to get into. But we’re also quite impressed that the software comes with makefiles that build the libraries and examples using your own GCC cross compiling toolchain. We spent quite … Read the rest
[Ronen K.] wrote in to tell us about the MOD playing Stellaris Launchpad project he recently completed. A MOD is a sound file for the computers of days long gone. But you’ll certainly recognize the sound of the 8-bit goodness that is coming out of this device.
To understand how a MOD file stores samples you might want to glance … Read the rest
