Picture Size Optimization for Embedded Systems

If you are developing an embedded system that requires a graphical user interface, you’ll likely have quite a few icons and/or images to store in the flash/rom. If your hardware has limited space, you may have to optimize the size of picture so that they can fit into your flash with no or minimal loss of quality. Reducing image size may also be of interest for mobile websites that can be accessed by devices with lower hardware specs and relatively low network throughput (EDGE/3G). I’ll use GIMP 2.6 – The GNU Image Manipulation Program to work on pictures in order to optimize their size. Selecting the picture format The most common picture file formats are bmp, jpg, png and gif. BMP File Format (aka Bitmap Image File or Device Independent Bitmap) can not compress images except for 8-bit color depth, so it is not suitable for embedded systems. JPG File […]

How-to Make WordPress iNove Theme Adsense Friendly

When I initially selected my WordPress theme, I did not really plan on using Adsense, so I just chose one which looked nice to me and fulfilled some other requirements. I finally went with iNove theme. However, after 3 or 4 months, I decided to give a go at Google Adsense and installed Advertising Manager plugin. I created a new Ad unit with a 300×250 resolution to put in the side bar, it was slightly cut on the right but was still looking OK. Later, I wanted to add a leaderboard ad (728×90) on top of the page to hopefully increase the CTR. However, that one was cut even more, although it looked OK in Chrome OS and Firefox, it looked awful in Internet Explorer. So I decided to adjust the size of the main section and the sidebar for iNove theme. Here are the steps to follow to resize […]

OLPC XO 1.75 Hardware, Firmware and Software

OLPC demo’ed their 3rd generation laptop – OLCP XO 1.75 – based on Marvell Armada 610 at CES 2011. The good thing about this platform is that they opened most of it including the hardware, the software and for the first time the firmware. However, I found out it’s not so easy to find the hardware / software development information and source on the OLPC site, so I’ve decided to make a summary and provide links to the hardware, firmware and software for OLPC XO 1.75. OLPC XO 1.75 Hardware The XO-1.75 is powered by Marvell Armada 610 CPU (88AP610) with an ARM core clocked at 1Ghz. It has 1GB DDR3 SDRAM, 4GiB NAND Flash, a TFT display, an SD Card slot, Wi-Fi, a few USB ports and a camera. I believe the touchscreen is not part of the current hardware, but the block diagram below should be close to […]
