The SDCC team is spoiling us with yet another great release. After a little less than one year of development and 3 release candidates the new 3.3.0 version is ready for download.
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.
Besides the numerous bug fixes here is a list of the important changes since the release 3.1.0 (list taken from SDCC website):
The Maxim MAX6675 and the newer MAX31855 thermocouple to SPI interface chips are very popular with electronics enthusiasts because of their extreme ease of use combined with good accuracy.
Both devices however are only available in SMD package making breadboard prototyping very difficult without using a suitable breakout PCB. Standard thermocouple connectors are also not breadboard friendly further aggravating the issue.
After about a year of development and 3 release candidates, the SDCC team has released the new 3.1.0 version of this great multi platform cross compiler for MCUs. This version supports: 8051, DS390, Z80, HC08, and PIC MCUs.
Besides the numerous bug fixes here is a list of the important changes since the release 3.0.0 (list taken from SDCC website):
LCD Smartie is a small application for windows that allow the user to display information on a separate text LCD display. In addition to the built-in system information and support for several popular applications it can be extended to display data from any source using plug-ins. This plugin makes available several key GPU parameters querying directly the NVIDIA display driver.
The freescale S08JS series is one of the lowest cost microcontrollers with a hardware USB implementation. The availability of free C development tools (SDCC and Codewarrior) make the S08JS a great candidate to develop all sorts of inexpensive USB gadgets. microJS is a fully functional S08JS minimal system on a PCB less than a square inch. The board headers can be plugged into a breadboard for prototyping or soldered to another PCB for a permanent placement.
