In this part of the series a method of using symbolic logic to represent HDL, when designing the architecture of a hardware algorithm, is introduced. The method is used to develop a modular, skeleton, device driver for TFT-LCD displays in general and the LQ043T3DX02 display (used in the Sony PSP) in particular. The design method introduced is used to generate a display’s horizontal and vertical synchronisation timing signals, by using its (the display's) timing characteristic parameters provided in its datasheet. Finally, by using a color look-up table a method of displaying images on the display is demonstrated.

In this article the fabrication, construction and assembly of a single sided, Plated Through Hole (PTH) component, DIY Printed Circuit Board (PCB) is demonstrated. The discussion presented shows how a PCB layout is fused onto a copper clad PCB using a laminator and toner transfer paper. It then goes onto to show how Sodium Persulphate can be used to etch the design.
