Creating the TV-50 A Model TV Simulator

In case you didn't know - I enjoy model building - specifically model railroading.  I have a website - GizmoFoundry where I sell the things I create. I thought I would run through the process of creating a simulator. In this case - the TV-50 which uses one of the basic PIC10F322 boards I created, specifically...

Z80 – CPU Intro

The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company's first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975. The Zilog Z80 is a software-compatible extension and enhancement of the Intel 8080 and, like it, was...

Image Processing – Color Image Arrays

Up to this point we have been dealing with Black and White images or Gray Scale images - that can be represented by a 2d array. Array(height, width) In which each element in the array represents one pixel and the level of gray, with 0 being black and 255 being white. A color image is made up of a combination of three...

Image Processing – Memory Usage

Something to consider is the memory usage for the images that you will be processing. Given a 100x200 image - black and white. That 100x200 array takes up roughly 20K of ram. If it is a color image, it would be 3 times that - because each color channel (RGB) is stored. Again, we are talking about RAW image data -...
