A2DGL() - A 2D Graphics Library: is a hardware accelerated graphics library for FPGAs and Microcontrollers. Mission Statement: produce a Borland(TM) BGI type graphics library with modern computer graphics constructs. Project Page:
The Missing Lecture Notes (MLN) series begins with Ben Popoola's popular series on hardware design. This series includes developing driver boards for the LQ043T3DX02 (Sony PSP) display, the OT-CO430-2P display and the development of a skeleton device drivers.
FPGA Design Tutorials. The first set of tutorials begin by developing a serial communications protocol between the DE0 Nano and a PC, using a USB to serial converter.

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.
