Fixing missing modules error in Raspbian

If you have used hifi's raspbian-ua-netinst, the unattended Raspbian installer, you might run into problems with modules:

depmod -a
ERROR: could not open directory /lib/modules/3.10-3-rpi: No such file or directory
FATAL: could not search modules: No such file or directory

I fixed this problem with:

 apt-get install git-core
apt-get install rpi-update
rpi-update
reboot

Note that this will also upgdare your firmware and the linux kernel!

Review of Arduino DAC solutions

Image
I was in a need of an analog output output for my Arduino, and I found quite many different digital-to-analog converter (DAC) solutions by googling around. So finally I decided to gather them on one page as a reminder for myself and a guide for others. So here it comes! R-2R ladder DAC The most common way to build a DAC is to use a R-2R ladder circuit. Make: Online has a photo-guide for building one. However, this DAC has no output buffer, which would make this circuit a bit more reliable and working with all kinds of loads. MAKE: Online's DAC shield Make: Online - Proto-DAC shield for Arduino A Direct digital synthesizer build using a R-2R ladder DAC - This is worth a look if you're interested in outputting audio. R-2R ladder DAC with output buffer For the best results, you should use an output buffer in the DAC. The buffer separates your R-2R ladder from the load you connect it to and makes the result non load dependent. Here's maybe the best tutorial I...

Free toolchains for STM32VLDISCOVERY

Image
How to program the STM32VLDISCOVERY board ? ST does not provide a toolchain themselves, instead there are three different officially supported toolchains available, for which ST has provided simple tutorials. All of the three official toolchains are for Windows, so Linux users have to think of something else. Fortunately, multiple options exist for also Linux users. Here's an overview of all the tools I'm aware of. First off, I'll explain the easy, official options. These are unfortunately only for Windows users. Officially promoted toolchains ST provides example code and documentation for three toolchains: Atollic TrueSTUDIO, IAR Embedded Workbench and Keil MDK-ARM. Download ST's example firmware package here User manual for the firmware package Below are some quick facts & links about the official toolchains. Atollic TrueSTUDIO (Windows) This is an Eclipse -based development platform that includes an optimizing C/C++ compiler, editor and a de...

Better output buffer for an R-2R ladder DAC

Image
One day I needed a simple R-2R ladder DAC, and needed an output buffer for it, so I started to design one. Initially I was planning to use the LM358, but then I remembered seeing an op amp from TI that would be more suited for the job. First off, I'd like to clear up two things for those that might wonder. Why I need an output buffer? For example the R-2R ladder digital-to-analog converter circuit cannot drive anything by itself. You should be able to observe the waveform with an oscilloscope (typically 1 megaohm input impedance) but probably cannot even drive a sound card input (~10kohm) with only the ladder. You need a buffer amplifier that has a voltage gain of 1 and can drive a low input impedance.   Why linearity is so important? So you get the value you wanted out from the circuit without any distortion. The TLV2472 single-supply op amp makes a great buffer. Unlike with the LM358 , the output is linear from 0 to VDD so you don't have to have an extra voltag...
