---------Ver 6.0----------------------------------- Date of release:28 june 2018 USB stack in interrupt, faster USB response. This modification purpose is to shut down the unit as soon as the OS is OFF during hardoff in Automotive mode. If bit6 is set in "Configuration flags" parameter: If 5VUSB is not present during hardoff the unit will enter low power mode immediately. If 5VUSB is present the unit will enter lowpower mode as usual after the timer elapses. ---------Ver 5.7----------------------------------- This modification purpose is to shut down the unit as soon as the OS is OFF during hardoff in Automotive mode. If bit6 is set in "Configuration flags" parameter: If 5VUSB is not present during hardoff the unit will enter low power mode immediately. If 5VUSB is present the unit will enter lowpower mode as usual after the timer elapses. ---------Ver 4.3----------------------------------- Date of release:30 sep 2013 1)Introduced possibility to start/stop the DCDC-USB device in automotive mode by using a pushbutton connected between IGNITION and VIN inputs. This is done by changing the specified bits in the "Configuration flags" parameter BIT 5: 1-ENABLE IGNITION PULSE 0-DISABLE IGNITION PULSE Default: Disabled for backward compatibility 2)"Ignition Debounce" parameter sets the time for the pushbutton debounce Value set back to 500ms for backward compatibility 3)Added Delay between output is ON and startup pulse is sent, some motherboards needs some time to wake up between output is ON and pulse is sent in order to boot properly Parameter name: ON Pulse delay Default is 0 sec for backward compatibility ---------Ver 4.2----------------------------------- !Custom firmware! Date of release:07 jul 2013 1)Introduced possibility to start/stop the DCDC-USB device in automotive mode by using a pushbutton connected between IGNITION and VIN inputs. This is done by changing the specified bits in the "Configuration flags" parameter BIT 5: 1-ENABLE IGNITION PULSE 0-DISABLE IGNITION PULSE Default: Enabled 2)Ignition Debounce parameter default value set to 50ms ---------Ver 4.1----------------------------------- Date of release:21 sep 2011 1) Introduced USB/"motherboard alive" sensing capability( this feature can be used with latest hardware version with separate USB header and connector) Off pulse is sent depending on +5VUSB state. This is done by changing the specified bits in the "Configuration flags" parameter BIT 4: 1-ENABLE USB SENSE 0-DISABLE USB SENSE Default: Disabled for backward compatibility 2) Introduced new parameter for Deep Discharge sensing during OFF delay in Automotive Mode Parameter name:"Min VIN voltage deep discharge". If voltage drops below this value for 5 sec off pulse is sent before the offdelay expires. Default value: 11.2V ---------Ver 3.1----------------------------------- Date of release:20 dec 2010 1)Introduced possibility to enable/disable the sending of ON and OFF pulses to the motherboard This is done by changing the specified bits in the "Configuration flags" parameter BIT 2: 1-ENABLE ON PULSE 0-DISABLE ON PULSE BIT 3: 1-ENABLE OFF PULSE 0-DISABLE OFF PULSE ---------Ver 3.0----------------------------------- Date of release: 15 Nov 2010 1)the THUMP timeout in AUTOMOTIVE mode is also active when DCDC-USB shuts down After the impulse is sent to motherboard the thump timeout becomes active and it will turn off thump after the timeout elapses 2)Added "Win7" support, had to change the bootloader also, so firmware version 3.0 are not upgradable through USB. It has to be flashed by a PIC flasher. Subsequent firmware versions 3.x (if any) can be upgraded by USB bootloader ---------Ver 2.1----------------------------------- Date of release: 19 Jul 2010 CHANGES: 1)Behaviour during hardoff in automotive mode changed: If Ignition is ON again the device will not wait for hardoff period to elapse. 2)New parameter flag introduced to configure the behaviour: a)"Configuration flags" If bit1=0 the device wil not turn off the output(NO powercycle) before begining a new cycle If bit1=1 the device will turn off the output (powercycle) before begining a new cycle Default is bit1=0. ---------Ver 2.0----------------------------------- Date of release: 25 Jan 2010 CHANGES: 1)Introduced regulation of output value according firmware measurements, this regulator can be disabled, if disabled output regulation behaves as in versions 1.x 2)New parameters introduced: a)"Configuration flags" If bit0=1 Regulator Enabled else Disabled, Default is Enabled b)"Max regulation step number" Maximum allowed steps the regulator can step to alter the output value. Default is 10 step c)"Regulator offset" The desired output value is offset-ed by this step nr to prevent overshoot/undershoot when regulation is applied. Default is 5 step. 3)BUG fix. fixed:In some very special circumstances case the firmware could have sent a false USB message ---------Ver 1.2----------------------------------- Date of release: 22 Oct 2009 CHANGES: 1)Changed the default voltage output values configuration to: 0) 12V 1) 5V 2) 6V 3) 9V 4) 13.5 5) 16V 6) 19V 7) 24V 2)Introduced the THUMP timeout in AUTOMOTIVE mode (When using +Vaux for thump) ---------Ver 1.1 first version in production------- Date of release: 01 Jul 2009 CHANGES: 1)In DUMB mode the main output and the auxiliary output can be controlled ON/OFF by jumping the 0 and 1 config jumpers respectively. 2)changed the default script ---------ver 1.0 first version--------------------- Date of release: 05 Dec 2009
