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.
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.
