1	Why I'm ditching the Arduino software platform I'm getting set up for my next project and decided to update my development environment. I've finally decided to entirely ditch the Arduino software environment and just use the boards. I stopped using the Arduino IDE some time ago, but now I'm going ...	29-Feb-2012 20:50:00
2	A mention on the Pragmatic Programmer I was looking at my Google Analytics and noticed I was getting referrals from the Pragmatic Programmer site, specifically from an article in the April magazine issue entitled Advanced Arduino Hacking. Turns out they were using my Makefile.master as the ...	08-May-2011 15:01:41
3	ATMega registers and memory ranges The AVR family has a reasonably complex register and memory architecture, with: Multiple address spaces Registers that can be accessed directly and via the memory address space Register pairs that are used as memory indexes Restrictions on which ...	10-Apr-2011 17:28:50
4	EletroAxé with Carlinhos Brown Carlinhos Brown is a colossus in Brazilian music, known not only for his solo musical career but also for the founding of Timbalada and for reviving the use of the Timbau, one of the instruments I (try to!) play. As part of this year's carnival in ...	01-Apr-2011 18:17:00
5	As it says, "Beautiful light performance" Well, we did our first performance with the LED strips on Wednesday at Islington Mill in Manchester,and I'm relieved to say they worked flawlessly, even after one of the wheels was dropped just before the performance started! The lighting in the venue ...	11-Mar-2011 23:01:00
6	Connecting a HL1606 strip to an ATmega I've been left a comment asking how the HL1606 strips are connected up to an Arduino. The wiring is really pretty simple, but depends on exactly which ATmega version you have, as the hardware SPI pins vary from MCU to MCU. The following assumes it's a ...	09-Mar-2011 23:29:00
7	I'm wheely pleased... Last night I met up with Andy and Colin of The Travelling Light Circus at MadLab to finally finish off some the LED strips that I've been working on for so long. The original plan was for them to be worn, which would have meant splitting the 4 20-LED ...	03-Mar-2011 08:46:00
8	Don't delay() It's very common for Arduino sketches to use the delay() library routine to control timing when performing time-related operations such as LED animations. Unfortunately delay() is toxic if you need to do more than one thing at once - for example ...	01-Feb-2011 21:23:03
9	Updated Makefile.master If you have been using my Makefile for Arduino sketches I've been updating it regularly with bug fixes and improvements. The latest version includes: Arduino bin directory, avrdude config file and avrdude path made configurable. Single-file sketches ...	23-Jan-2011 12:22:56
10	Optiboot on Arduino Pro Mini The newer Arduino boards such as the Uno include a new bootloader that takes up about 1/4 of the size of the old one. That means some extra memory can be freed up for applications. The new bootloader is known as Optiboot, and the site says "Compatible ...	21-Jan-2011 14:17:50
11	Radio-controlled HL1606 strips Well, I've finally finished the design and implementation of the radio-controlled LED strips I've been asked to make for The Travelling Light Circus. It's taken far longer than I expected, but I've learned an immense amount in the process. The ...	15-Jan-2011 18:07:19
12	Waiting for O(1) Due to a misconfiguration the notification emails from my blog weren't reaching me, so I missed a couple of interesting comments on my earlier HL1606-related posts. The ones from Dan from over at Waiting for O(1) were particularly interesting, and he's ...	19-Oct-2010 18:14:11
13	Switch debouncing, the hard and the soft way I'm using a quadrature encoder for my LED lights project, to allow the controller to select the pattern that is to be displayed. The encoder consists of two parts, a momentary push button switch activated by pushing the shaft down, and a rotary encoder, ...	23-Sep-2010 22:15:00
14	Updated Makefile.master If you have been using my Makefile for Arduino sketches I've been updating it regularly with bug fixes and improvements, the latest being automated header file dependency checking. You can find the current version of the Makefile.master here.	12-Sep-2010 21:39:00
15	PROGMEM and GCC bug 34734 The Atmel AVR CPUs that are used in the Arduino boards aren't the familiar Von Neumann architecture machines we are all familiar with, where there is a "flat" address space that's shared between both code and data. Instead they are Harvard Architecture, ...	05-Sep-2010 21:50:00
16	SparkFun are less than electrifying As part of my LED strip project I needed a 7-segment display capable of displaying two or more digits. I could have built something myself, but I'm short of time as it is so the SparkFun kelly green seven-segment serial display seemed like a good ...	28-Aug-2010 20:10:57
17	A very simple Arduino task manager The LED chain project I'm working on requires that the AVR microcontroller handles several different tasks: Read a rotary encoder and switch Drive a seven-segment display Drive a radio Drive four LED strips each containing twenty LEDs Provide logic to ...	20-Jul-2010 19:07:00
18	Characterising the 7805 As the LED strips are going to be mobile, I needed to find a way of powering them. After some investigation, the 7.2 volt NiMH battery packs used by radio controlled cars seemed like a good choice - they are high capacity, relatively cheap and readily ...	30-Jun-2010 17:54:00
19	Configuring NetBeans to use as an Arduino IDE As I've said in an earlier post, I very quickly found the Arduino IDE to be way too primitive for serious use, so I decided to switch to using NetBeans as an alternative. First step was to create a Makefile, once I had that done I needed to configure ...	22-Jun-2010 20:09:00
20	AVR SPI gotcha I've had all sorts of problems getting a SPI radio device to work for the last few days - I wasn't using the default /SS pin to select the slave as I was reusing some code from another program that already used the default /SS pin for a different device. ...	13-Jun-2010 22:30:00
