Change Log

  • BeRTOS 2.3.0 released (19 Oct 2009)
    • Fixed a bug in AT91SAM7 SPI1 driver
    • New CRC-CCITT algorithm
    • New KFileMem module: kfile over a memory buffer
    • New AX25 protocol suitable for ham radio APRS enc/decoding!
    • New AFSK1200 modem driver!
    • New NMEA-0183 (GPS) data parser (thank to NMEAP library:  http://nmeap.sourceforge.net/)
    • New LM75 temperature sensor driver
    • New TMP123 Texas Instruments temperature sensor driver
    • New MPxx6115A pressure driver
  • BeRTOS 2.2.0 released (18 Sep 2009)
    • Now BeRTOS has full DOS FAT support, thanks to FatFs driver! (see  http://elm-chan.org/fsw/ff/00index_e.html)
    • New driver SD card: you can read/write files from Secure Digital cards.
    • Flash and debug infrastructure integrated into the build system. Now flashing a target is just a make flash away!
    • New module kfile_fifo: you can now use the KFile interface over a FIFO buffer!
    • Fully functional priorities for processes.
    • New module ini_reader: you can read ini files to configure your application!
    • New module kfile_posix: you can use the KFile interface with Posix systems test your code.
    • New driver I2S: you can use the I2S bus to output music. Only AT91SAM7 is currently supported.
    • New driver TAS5706A: now you can control this 5.1 Dolby Digital audio DSP with BeRTOS!
    • These files are considered DEPRECATED and will be removed in the next version:
      • mware/byteorder.h
      • mware/rle.h
      • mware/pgm.h
    • Lots of bug fixes.
  • BeRTOS 2.1.0 released
    • Add the BeRTOS Wizard, a tool to generate and configure BeRTOS projects with a comfortable GUI
    • Build infrastucture can now compile different architectures at the same time
    • Add a new Watchdog generic interface
    • Allow the build system to build emul with QT without pkg-config on Mac OS X
    • Improve the KFile module with the resync generic function
    • Generalize xmodem with kfile interface
    • Completed the automated BeRTOS testsuite
    • Completed the Kernel testsuite
    • The CLOCK_FREQ macro and the hw_cpu.h file are now obsolete. Now, you should pass a macro called CPU_FREQ directly from gcc command line. The old method is still supported for now for backward compatibility.
    • All switch context assembly files are now named with the prefix "switch_ctx_" in order to be easier for the Wizard to find the right file for a given architecture. The old files are deprecated but are still present. They will redirect to the new ones for backward compatibility issues.
    • Add full support for Atmel AT91SAM7S64, AT91SAM7S128, AT91SAM7S512, AT91SAM7X512.
    • Change timer and adc compilation behaviour: the CPU dependent timer and adc modules are no more automatically included. You have to include the CPU specific files (eg: timer_avr.c or timer_at91.c) explicitly in the makefile. This is necessary to uniform the timer and the adc to other CPU dependent drivers behaviour.
    • Add an example project for the AT91SAM7X256
  • BeRTOS 2.0.0 released
    This is a major refactoring version, there are huge changes in interfaces and a lot of new features.
