Optimising mathematical operations for Arduino

 After working with various sensors and not being happy with the speed of mathematical calculations, Arduino and AVR enthusiast Alan Burlison has described and demonstrated the use of fixed-point arithmetic with Arduino. This method can speed up calculation times and is necessary as the AVR microcontrollers used in the Arduino don't have floating-point support. Alan demonstrates various functions and in doing so illustrates the strengths and weaknesses of the AVR - even working down to the assembler level. 

Interesting reading, and useful for those of you squeezing the most out of your microcontrollers. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're making things that push an Arduino to the limit, or if your projects outgrow the normal Arduino-compatible boards, running out of program and flash memory space, or you're stacking on Ethernet and microSD shields, or all at once - it's time to upgrade to the Freetronics EtherMega:

Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
