High power LEDs require a constant current power supply for optimal operation. GLED1 is designed to drive 10W white LEDs (9 diodes in series) from a 12V or 24V supply. The board can be used down to 3V but the maximum output power will be reduced in this case. The design supports discrete level dimming using a two or three way switch or continuous control using a PWM signal. The design is based on the ON Semiconductor NCP3065/3066.
GGLABS and our good friends at FLIRC will be sharing a booth at the East Bay Mini Maker Faire on October 19th. If you plan to attend the faire stop by our booth to check out the features and ease of use of FLIRC and other miscellaneous GGLABS projects. We will be also showing some projects still in development stage that have not been published yet.
We are proud to announce that gglabs was chosen by the LCD Smartie team to design a custom USB interface for text displays specifically designed for LCD Smartie. The result of our collaboration is the LCD Smartie official hardware. Beside purchasing the most advanced USB based LCD interface on the market, your money will serve good cause as part of the profits will go to the LCD smartie developers.
Besides the numerous bug fixes here is a list of the important changes since the release 3.2.0 (list taken from SDCC website):
Our staff has been working with Freescale to negotiate the release of S08 header files under a free software license to allow their inclusion in the SDCC distribution.
After more than one year of work and the superstar effort of Jim Trudeau at Freescale we finally received the package under the BSD 3-clause license.
