Known issues:

• File downloading (from host PC to the EEZ H24005) using serial port frequently failed because a data chunk for unknown reason never reach the MCU (i.e. Arduino Due). That issue does not exist on Ethernet connection regardless of data chunk size.
• Disconnecting of USB cable while serial communication is active can block Arduino Due because Arduino library will wait indefinitely since serial buffer cannot be emptied.

• #122 Change trigger mode when trigger is active
• #161 Selftest failed on serial remote session when temp sensor is not detected
• #162 Can't exit screen lock after reboot, date/time dialog present
• #166 Pin1 inhibit functionality
• #167 Invalid protection trip condition when enters coupling mode
• #170 YT-view display issue
• #171 Calibration params cannot be saved
• #172 SYSTem:COMMunicate:ENABle does not affect displayed icon
• #173 User profile recall can affect output state when protection trip is not cleared
• #174 Restarting list when trigger is still active

This release is a hot fix to address #149 issue with calibration on older Power boards (r5B9) and strange behavior of channel settings. Another important change is #135 that now allows selection of USB port during compilation time. The so-called native port is now set as default one. Therefore PSU will not be restarted each time a new serial communication is established. In addition the following small fixes are included:

• #150 Changing luminosity of background colors
• #151 Touch screen calibration error last too short
• #153 Channel output on/off should respond on touch down
• #154 AUX temp sensor clear option behavior when disabled
• #155 Tracking and coupling options if two channels are not available
• #156 Compilation error when all debug options are disabled

Release uploaded on Arduino Due delivered to backers of group buy organized as crowdfunding campaign on Crowd Supply. The following changes and improvements are added into this release:

• #99 Indication that LIST is running with long DWELl times
• #109 Serial/USB communication settings
• #110 Additional Ethernet settings
• #113 Additional date/time settings (NTP, DTS support)
• #115 Limit number of remote requests
• #120 Add support for digital I/O
• #124 Max. input voltage protection in remote programming mode
• #127 Short flash of all front panel LEDs during selftest procedure
• #129 Protection trip cannot stopLIST
• #131 Icons for AUX temp sensor, serial and Ethernet
• #132 Change trigger mode cannot stop LIST
• #137 Changing luminosity of background color
• #138 Start of calibration procedure cannot stop LIST
• #142 Continuous switching current ranges when output is in UR mode (see also #106)
• #146 Current range switching when output is enabled

List of known issues and not implemented but possibly useful enhancements:

• Output voltage offset when RSENse is not active (#67)
• Measure output voltage before output is switched on (#89)
• High range current calibration compensation (#100)
• Battery temperature sensor is not supported (#143)

New Arduino shield r5B12 and Power board r5B12 with dual current range is now supported (#92, #108). That include auto-ranging feature. Output values set and measurement precision is now improved (#91) and for current it can be 0.1 mA (low range) and 1 mA (high range). Few other bug fixes and small improvements are also included in this release:

• #45 First time installation wizard

• Arduino board r5B12 (EEZ_PSU_SELECTED_REVISION)

Define other Arduino board (i.e. r3B4) or disable unsupported/uninstalled options in conf_user.h before compiling.
