Version 0.4.5 (Commit 0b3f025 August 25, 2023):

  • Migrated to VS 2022 (version 17.7.2)
  • Updated PCANBasic DLL (version 4.7.1)
  • Updated CAN API V3 sources to rev. 1155 and applied the changes:
    • Added old error code -40 as queue overrun error and renumbered error error frame received from -40 to -19
    • Removed unused error code CANERR_ERR_FRAME (note: the error code -19 is marked as reserved)
    • Removed flag fdoe and brse from struct can_speed_t (note: the flags are marked as reserved)
    • Integrated reworked module can_btr:
      • btr_check_bitrate: if FDOE w/o BRSE then check data phase field acc. OPTION_CANBTR_DATA_FIELDS
      • btr_bitrate2speed: no range checks anymore, calculation is done completely in float
      • btr_bitrate2index: returns the index if an index is given
      • btr_bitrate2string: no range checks anymore
      • btr_sja10002bitrate: set data phase field acc. OPTION_CANBTR_DATA_FIELDS
      • btr_compare_bitrates: comparision on basis of transmission rates (new function)
      • Removed flag fdoe and brse from struct btr_speed_t (standalone variant)
      • Documented all interface functions by Doxygen comments
      • Added header file CANBTR_Defaults.h
      • Reworked the bit-rate string scanner (btr_string2bitrate):
        • Return a flag if any data phase key is found
        • Return a flag if no. samp. key is found
        • Return BTRERR_ILLPARA on error
        • Removed the range checks
        • Set miminum frequency to 1
        • Checked for duplicated keys
        • Accept only case sensitive keys
      • Reworked the bit-rate string printer (btr_bitrate2string):
        • Added a parameter to output data phase keys
        • Added a parameter to output no. samp. key
        • Added a parameter for maximum buffer size
      • Fixed a bug with strtol if a correct value is outside the range of representable values (note: long is 32 bit wide for MS compilers and 64 bit for gcc based compilers!)
    • Added property values for transmit queue properties (note: values for filtering has been shifted by 8)
    • Fixed a bug with saturation of CAN FD DLC conversion
    • Updated description of compiler switches
  • Reworked handling of status and error frames
  • Removed old bit-rate mapping functions
  • Fixed a bug with property GET_DEVICE_NAME
  • Synchronized the Utilities with MacCAN-Wrapper
    • Fixed an issue with option --verbose
  • Added CAN API V3 Tests with GoogleTest
