v0.4.1 Fix compiler warnings

A simple compiler warning fix for an unused variable. There are no functional changes.

v0.4.0: Add Y700 Pressure/Depth; Improve Y4000 Sonde

The YosemitechModbus library enables use of an Arduino-framework board as a Modbus RTU master to control and communicate with the sensors produced by Yosemitech via over RS-485.

New Features

• Added support for the Y700 Submersible Pressure Transducer / Water Depth sensor, which is a prototype that is not yet posted on YosemiTech's website. #29

Improvements

• Improved Y4000 Multiparameter Sonde implementation, fixing a bug that inhibited output of Chlorophyl and Blue-Green Algal data when those optional sensors were installed on the sonde. #13
• Improved GetValues.ino to provide response timing information to explore real-world warmup, stabilization, and measurement times for each sensor. #15

For a full list of changes, see PR for release v0.4.0.

[0.3.1] 2022-03-01

Changed

• Modified example to demonstrate use with Espressif processor

Added

• Restored backward compatibility with Y550
• Added github actions to test code
• Created ChangeLog and Version files

v0.3.0: Add Y551 COD and Y560 Ammonium sensor support

New Features

• Added support for the Y551 COD Sensor, which makes a UV254 light absorption and translates it to estimates of Chemical Oxygen Demand (COD) (or Total Organic Carbon (TOC)) and Turbidity.
  • NOTE that this upgrade removes the earlier Y550 from the library, as it was never tested and is no longer available form YosemiTech. If anyone has a Y550 sensor, the Y551 commands should work. Let us know if they don't.
• Added support for the Y560 Ammonium Probe, which is a mini sonde for three Ion Selective Electrode (ISE) sensors (pH, NH4+, K+) that together are used to provide a corrected estimate of total ammonium nitrogen (NH4_N) in mg/L.
  • NOTE that this release only includes outputs for NH4_N, pH, and temperature. A future release will also include estimates of potassium (K) and raw potential values from each of the electrodes.
• Added User Manuals and Modbus Manuals for both new sensors

v0.2.4: Update version tags for PlatformIO Library Registry

Update version numbers for proper release

So it registers in the PlatformIO Library Registry at https://platformio.org/lib.

v0.2.3: Fix to Y533 ORP; updated manuals & software

• Separation of the Y533 ORP getValues from Y532 pH, fixing the issue raised with #19.
  • The new getValues command for the Y533 now returns Electrical Potential (mV) as the primary parmValue.
  • Replicated fix to startMeasurement return, which is required to get Y532/Y533 to work as a stand-alone sensors in ModularSensors.
• Updates to Windows software utilities and documentation
  • new SmartPC v2.4 software
• Many updates to YosemiTech manuals
  • Note that YosemiTech is now providing product manuals on their website under the Resources menu. See http://en.yosemitech.com/aspcms/downlist/list-23-1.html
• Several updates to calibration spreadsheets & protocols.

v0.2.2: Better Y532 pH support, updated manuals & software

• Fix to Y532 pH startMeasurement return, which is required to get Y532 pH to work as a stand-alone sensor in ModularSensors. Commit 574a31c.
• Updates to Windows software utilities and documentation
  • ModbusRunner v2.5.1.5
  • MulitSensor v1.9
• Updates to YosemiTech manuals
• Updates to calibration spreadsheets & protocols. Issues #14, #16.

Fixed setCalibration

Fixed problem with setting calibration constants. Both values must be set in a single command.
