Driving the PSP display with a FPGA

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

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.

In the News #5 - The Arduino TRE

Hot on the heels of the Raspberry Pi 2 Model B+ with its quad core processor, Arduino are set to release the Arduino TRE consisting of an AVR arduino and a 1-GHz Sitara AM335x processor, which allows makers to get up to 100 times more performance than the Arduino Leonardo or Uno. The TRE is set to host a Linux operating system that will allow users to run processing-intensive algorithm and high-speed communications, alongside the Arduino's traditional applications. Sounds similar to Intel's Galileo doesn't it? Also, this will be the first Arduino manufactured in the U.S and not in Italy or China.

In the News #4 - The ARM, IBM Internet of Things Starter Kit

ARM and IBM have teamed up to produce an Internet of Things (IoT) starter kit, consisting of an ARM mbed enabled development board and an application board containing sensors. The kit has been designed to "spur on the invention" of Internet-connected gadgets in about five minutes, that is, from the time the kit is unboxed. It works by allowing the devices, hosting an ARM Cortex-M4 processor, to connect to IBM's cloud services and start sending readings to online apps.

In The News #3 - FTDI's SuperSpeed USB3.0 Devices

FTDI are set to release a series of USB3.0 devices to complement their renowned USB endpoint-to-FIFO bridge USB 2.0 (FT232H) and USB 1.1 (FT245) ones, which have been available for a few years.  Available with optional 16-bit and 32-bit FIFO interfaces, the FT600 will be the first device released in the series. This is splendid news and music to the ears of the FPGA community, as the device could be used to  provide FPGA enhanced applications with simplified connectivity to host computers, with data transfer rates of up to 5 Gpbs.

In The News #2 - The Raspberry Pi 2 Model B+

Without much fanfare the new Raspberry Pi 2 (B Model) has arrived on our doorsteps, well ours  did! This is the first major upgrade the world's most popular single-board computer has received, since its first release in 2012. This is a much needed upgrade that allows the Pi to compete against its faster contemporaries, including the Beagle Bone and the Banana Pi.

In The News #1 - Free Non-Commercial Renderman

For years 3D animation hobbyists interested in Renderman, but not wanting to fork out the ££££ required for a  license, have had to rely on third-party REYES compliant renderers like, Aqsis (a favourite of ours), Pixie, Gelato, Angel and others.

Previously, we had used Aqsis, however in 2015, Pixar the owners of Renderman are due to release a free. non-commercial, version of their famous software.

Lattice Semiconductor must be strong believers in the phrase "less is more", as by providing this minimalist iCE40HX8K Breakout Board they expect one to work one's butt off to get the most out of it. However, they could only be described as true democrats, because not only is the board minimalist so is its sparse user guide, as well the challenging documentation on using the development  software, iCEcube 2.

This means that if you love the excellent iCE40 family of FPGAs, like we do, you need to be prepared to bring your "A" game to the digital design fiesta, like we had to, when figuring out how to use this particular FPGA development board.

Everything should be made as simple as possible, but not simpler - Albert Einstein.

Previously, we gave our first impression of the crowd funded iSketchNote, which although showed great promise appeared not to be quite ready for market release. Well, since then the guys at ISKN appear to be working very hard  and have produced updates for both the iPad app and the iSketchNote's firmware. So we decided to offer our second, humble, opinion. Here is what we think.

Ronaldo, the Portuguese one, has been named as this year's FIFA Ballon d'Or winner, that is he has been nominated as being the best footballer, or soccer player to some, in the world. He is described, arguably, as the most complete player of this generation of Champion's League footballers. Although, Lionel Messi might have something to say about that.

Just like Ronaldo, the Portuguese one, the SoCKit, originally developed by Arrow Electronics, could also be described as the most complete low-cost FPGA development board in the world. It could be, arguably, the best ever FPGA development kit for hobbyist System-On-Chip (SoC) and FPGA developers of its generation.

He wears a No. 10 jersey. I thought it was his position, but it turns out to be his IQ - George Best on Paul Gascoigne

However, unlike Ronaldo who is reportedly worth between €200 million to €300 million on the transfer market, in this blog we present the case why we feel our SoCKit is priceless.

When I was younger, much, much younger than I am today I remember reading a novel about an ex-boxer turned petty crook who had been in so many fights that the author described him as having a face that only a mother could love. Every time I look at the MachXO3L Breakout Board, the version with SMA connectors, the description of the ex-fighter  comes to mind. It's not that the board is "that" unpleasing to the eye, it's that it just looks, well, so functional and business-like. 

My mother said to me, 'If you are a soldier, you will become a general. If you are a monk, you will become the Pope.' Instead, I was a painter and became Picasso - Pablo Picasso

In this blog post we gloss over the Board's less than exciting appearance and evaluate it solely on its functionality.

I love drawing, but I've never given myself a chance to become any good at it. I love my iPad (iPad Air) too. Hence, when  I saw a device, the iSkecthNote, that happily married the two I didn't hesitate to help fund it, when it was introduced on the crowdfunding website, Kickstarter.

However, as has been symptomatic of Kickstarter projects, this one was delivered late too, but this time I didn't mind. This was because I thought that the wait would be well worth it.

When the engineers behind iSketchNote conceived of the idea they probably thought that it was very good one and if they turned it into a product they might be able to sell a few. They were wrong, it is an absolutely brilliant idea and it wouldn't surprise me if they end up selling them by the bucket load. This is my first impression of using the iSketchNote.

Just after finishing this article ISKN released app version 2.1 and the Bluetooth connectivity pairing issues seem to have improved.

UPDATE: 14/02/2015: I have now posted a follow-up review
