HydraFW v0.5 Beta

• New USB VID_0x1d50/PID_0x60a7 using OpenMoko HydraFW, update with new drivers
  • Windows see driver_usb_cdc/hydrabus_usb_cdc.inf
  • Linux see 09-hydrabus.rules
• Added USB DFU boot by pressing UBTN at PowerOn/RESET for easier future update of the firmware (does not requires any wire).
• Added Log command (thanks to biot):
  • Log all commands/answer in the Terminal to HydraBus SD card file: logging on off sd
• Added command debug test-rx (debug rx) in order to test USB CDC reception performance.
• Added PWM command:
  • Configurable PWM frequency between 1Hz to 42MHz and duty cycle from 0 to 100%: pwm, frequency, duty-cycle
  • Give feedback of real PWM frequency & duty cycle after configuration.
• Added DAC command:
  • Configurable DAC1(PA4 used by ULED) or DAC2(PA5) with following modes:
    • raw (0 to 4095), volt (0 to 3.3), also returns feedback of raw/volt DAC value after configuration.
    • triangle (5Hz / 3.3V Amplitude), noise (0 to 3.3V Amplitude)
    • dac exit disable DAC1/2 & Timer6/7 and reinit GPIO for PA4 & PA5
• UART:
  • UART returns real baud rate+% error after configuration.
  • Check and correct min/max value for UART baudrate.
• I2C added scan (thanks to biot).
• SPI:
  • Fixed cs on / off bug with Infinite Loop.
  • Fixed SPI mode slave.
  • Fixed configuration for phase & polarity (was always set to 0).
• HydraNFC:
  • Fixed HydraNFC detection/init/cleanup and autonomous sniffer mode started with K4.
  • Fixed some potential problems/crash with scan/continuous.
• Add full help for commands.
• Lot of cleanup and fixes in code.
