Summary

We have purchased over $9000 worth of Bolivian Rosewood and the tools necessary for installation. After I took my time off work and finished a small room of 100 sq ft, we found out that the rest of wood was not packaged correctly and had various damages and scratches. We spent a good amount of money for genuine rosewood molding and stairnose, but it turned out to be ...

PDF Tools

After a long search (see session below), I came across this tool for PDF annotation. PDF Tools is a DocView replacement for pdf on steroids. It renders pdf files in memory on demand, thus allows much extended capabilities, such as annotation, search and lots more just like another org file. See it in action here or my screen cast.

  1. Install pdf-tools from pinguim06 branch.

Access SD Cards from TFT LCD Shield Using Arduino Mega 2560 Soft SPI

Posted by:

Preamble:

Some things to keep in mind when using the SD Library -from official site and SD library

The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 (on most Arduino boards) or 50, 51, and 52 (Arduino Mega). Additionally, another pin must be used to select the SD card. This can be the hardware SS pin – ...

Arduino TFT LCD GUI – Load Bitmap Image

Posted by:

Preamble

There are two ways to draw bitmap images in Arduino TFT LCD – to draw from SD card, or convert them into byte array. The first is more powerful and works with true color bitmap images; the 2nd approach is more suitable for simple logo and monochrome images, and there is no need for SD capability for this method.

Convert Images to C++ Byte Array

There are a ...
