Embedded newbie: February 2011
http://embeddednewbie.blogspot.com/2011_02_01_archive.html
Monday, February 7, 2011. Review of Arduino DAC solutions. 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! MAKE: Online's DAC shield. Make: Online - Proto-DAC shield for Arduino. A Direct digital synthesizer build using a R-2R ladder DAC. R-2R ladder DAC with output buffer. This design...

Embedded newbie: Overview of the LPCXpresso development platform
http://embeddednewbie.blogspot.com/2011/03/overview-of-lpcxpresso-development.html
Monday, March 14, 2011. Overview of the LPCXpresso development platform. I got hold of the LPCXpresso development platform. This is a nice, thin 32-bit development platform with a built-in USB programmer for only 20€. The LPCXpresso. On the right is the target board, on the left is the LPC-Link USB JTAG debugger. The separated LPC-Link debugger. Picture: NXP. This article focuses on the LPC1114 version. The LPC-Link portion of the board uses a LPC3154 for the debugging. Looking at the datasheet. LPCXpres...

Embedded newbie: Fixing missing modules error in Raspbian
http://embeddednewbie.blogspot.com/2014/03/fixing-midding-modules-error-in-raspbian.html
Tuesday, March 18, 2014. 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:. 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:. Note that this will also upgdare your firmware and the linux kernel! Subscribe to: Post Comments (Atom). Review of Arduino DAC solutions.

Embedded newbie: April 2011
http://embeddednewbie.blogspot.com/2011_04_01_archive.html
Friday, April 29, 2011. Better output buffer for an R-2R ladder DAC. 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. Why linearity is so important? The LM358 has b...

Wednesday, March 19, 2014. Backing up the Raspberry Pi SD card. Since there's a lot of talk about corrupted SD cards, I decided it's best if I take a backup of mine every now and then, to ensure I don't lose all my work due to some stupid corruption. There's many different reasons for the corruption problems: faulty memory cards (SD cards have a limited number of read/write cycles, especially the older ones), counterfeit SD cards. Never buy your SD card off eBay! I use the free program Win32 Disk Imager.

Embedded newbie: Getting sound to work on the Raspberry Pi
http://embeddednewbie.blogspot.com/2014/03/getting-sound-to-work-on-raspberry-pi.html
Tuesday, March 18, 2014. Getting sound to work on the Raspberry Pi. I wanted to try out audio on the Raspberry Pi, using the Raspbian OS. Here's how I got it to work. The installer I used for Raspbian was the minimal network installer by hifi. This will use up only about 150MB of space and will not install a desktop, so you'll save a lot of resources with this approach. After installing Raspbian, this is what I needed to do in order to get sound output. Update the package list for APT. Linux pi 3.10&...
