HydraBus v1 Rev1.5

Updated commands:

• Native commands show, logging
• ADC guide, DAC guide, PWM guide, GPIO guide

See: https://github.com/bvernoux/hydrafw/wiki/HydraFW-commands

• 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.

Release with pre-built firmware: https://github.com/bvernoux/hydrafw/releases/tag/v0.5-beta

BlackMagic has been ported to Hydrabus and is fully working with JTAG & SWD.
(Tested JTAG/SWD debugging on target STM32F4 & LPC4330)

For more details see:

Major improvement/refactoring towards terminal/syntax using tokenline (instead of microrl) thanks to Bert Vermeulen (biot) for that amazing piece of software and all the work on this project.
Also lot of new commands added like ADC, GPIO, more sd commands.
SPI1&2, I2C and UART1&2 are tested with logic analyzer/oscilloscope.

Release with pre-built firmware: https://github.com/bvernoux/hydrafw/releases/tag/v0.4-beta

Also a very good news now HydraBus have OpenMoko USB VID/PID see more details here
Those ID will be used in next release HydraFW v0.5

In latest version of HydraFW support of EmBlocks IDE have been added to simplify development, build and debug.
Thanks to rdollet for this contribution.
In order to build HydraFW it is required to install mingw (mainly for sh) & python 2.7 (for pre/post build).
When you have installed EmBlocks you just need to Open file "hydrafwEm.ebp" available in root of hydrafw github source code.
Also now code is compliant with Linux Kernel coding style.

For this new version the following modes have been added: SPI (Master & Slave), I2C (Slave only) & UART.
Also lot of fixes and cleanup.

HydraFW v0.2 Beta is coming including template draft of mode plugin with same syntax as "buspirate" commands: see https://github.com/bvernoux/hydrafw/tree/master/hydrabus files xxx_mode_xxx.c/.h

This version add new sd commands and a microSD benchmark command (sd_rperfo) which run at up to 20MBytes/s

VT100 terminal is also now fully working thanks to Bert Vermeulen (biot) for the fixes in microrl and contributions for hydrafw code.

HydraFW is a native C (and asm) open source firmware for HydraBus board with support of HydraNFC Shield.

This version is basic and mainly for HydraNFC users waiting sniffer mode for NFC ISO/IEC 14443 Identification cards.
The firmware can be installed without recompilation (dfu binary included) by following the 7 steps to flash their HydraBus board.
It is available on github:
https://github.com/bvernoux/hydrabus/tree/master/firmware/hydrafw

HydraBus and HydraBus Case are now available on SeeedStudio Shop

For HydraBus related tools see :

http://www.seeedstudio.com/depot/HydraBus-m-132.html

The HydraFW (common to HydraBus and/or HydraNFC) will be available on 21 September.
