// -----------------------------------------------------------------
// PERSEUS RECEIVER CONTROL DLL FOR WINRAD
//
// SOFTWARE RELEASE NOTES
//
// Version: 	2.4a
//
// Date: 	September 2014
//
// -----------------------------------------------------------------


BUGS FIXED in v2.4a (NEW)

- USB data transfers size changed to multiples of 512 bytes for USB3.0 chipsets compatibility
- FPGA configuration moved in the StartHW() call and called when required

FEATURES included from v2.3b

- The control DLL now supports also the following sample rates:

  a. 95.238 ks/S (used by Joe Taylor's K1JT MAP-65)
  b. 48 kS/s
  c. 96 kS/s
  d. 192 kS/s

  Since the digital down converters cores of the Perseus receiver
  do not implement fractional decimation and the A/D converter sampling
  frequency is 80 MHz, these rates are only approximate.
  The MAP-65 rate is obtained dividing the ADC clock by 840.
  The 48, 96 and 192 kS/s rates are obtained dividing the ADC clock by
  1664, 832 and 416.

- The new perseususb.dll with WinUSB drivers support.
  Users which wishes to use the Perseus receiver with Winrad should either 
  install the WinUSB drivers provided with the Perseus software (v2.1h)
  on their system or continue to use the perseususb.dll provided with
  older distributions and the old CyUsb.sys driver.

BUGS FIXED in v2.3b

- The DLL checks for the Perseus hardware at software startup as per
  the ExtIO_xxx Winrad DLL specifications.
- The DLL GUI is shown correctly when the unhide "H" key is pressed in Winrad

NOTES

- The record button of the Perseus receiver control panel has been mantained
  for compatibility with the Perseus wav file format.
  Files recorded with the Winrad Rec button are not compatible with the
  format used by the Perseus software.

- All the files of this distribution should be copied to Winrad's folder
