What's new in BeRTOS 2.5.1:

September 6th, 2010

· This release fixes a build bug in empty and kernel presets for lm3s-based projects. All users are encouraged to upgrade their existing installations.

What's new in BeRTOS 2.4.0:

March 24th, 2010

· Synchronous Timer Scheduler: convenient API to perform periodic tasks on very tiny embedded systems.
· Preemptive Scheduler: a long awaited feature is now in BeRTOS!
· New driver: Texas Instruments TLV5618 DAC module
· Add heap module to the Wizard: now you can use and configure the BeRTOS dynamic memory allocator directly from the wizard.
· Dynamic memory allocation for processes: you don't need to provide a memory area for your processes, the stack will be automatically created by the kernel.

What's new in BeRTOS 2.3.0:

October 20th, 2009

· This release adds the CRC-CCITT algorithm (a standard CRC algorithm), the AX25 protocol (a communication protocol used extensively on amateur packet radio networks), the AFSK1200 modem driver (a modem built on top of AFSK modulation), NMEA-0183 (a data parser for GPS packets based on the nmeap library), National LM75 and Texas Instruments TMP123 temperature sensor drivers, a Freescale MPxx6115A pressure sensor driver and the KFileMem module (a KFile interface on a memory buffer).
· The Website is now available in English.

What's new in BeRTOS 2.0.0:

November 13th, 2008
