Many MCU applications use electro-mechanical relays to control AC loads. While this is an excellent solution for occasionally turning on/off a load it is not suited for frequent switching or PWM applications. SSR01 is an opto-coupled solid state relay that can control two AC loads up to 16A each.
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.
Despite the significant advantages in size, weight and efficiency, switching AC-DC supplies are not very common with hobbyist due to their complexity and scarcity of ready to build kits.
PWR01 is a low power (~6W) universal voltage (100-240V) isolated AC-DC flyback converter based on the ST Microelectronics VIPer17. Either 5V or 12V output can be obtained using an off the shelf transformer.
Linear regulators from the 7800 series are often the choice for electronics hobbyists because of their ease of use, versatility, robustness and availability. G78xxHE is a very small DC-DC converter aimed to be a "drop in" replacement for the 7800 series regulators in TO-220 package. Thanks to its high efficiency the G78xxHE does not need to be connected to an heatsink even when delivering the maximum rated 7800 series current (1A) with large Vin-Vout deltas.
The SDCC team has been quite busy lately and they managed to put out yet another great release of the best free software compiler for microcontrollers. Version 3.2.0 adds S08 support (making our staff incredibly happy) and revives the support for gbz80.
