LabJack Release Notes

R3-0 (November 25, 2022)

Rewritten to be based on asynPortDriver using the vendor LJM library, rather than low-level Modbus access.
Added waveform digitizer support, which is called streaming input in LabJack terminology.
Added waveform generator support, which is called streaming output in LabJack terminology.
Added support for selecting the range and resolution of the analog inputs.
Added the ability to enable/disable each analog input channel.
- Improves data quality by disabling unconnected inputs.
- Improves the polling speed by not reading disabled inputs.
Added support for thermocouple inputs.
Changed the binary input/output direction to be configurable for each bit.
Added support for the new T8 model.

Many changes to simplify and add new features.

Added support for the analog input Range feature to select the voltage range.
Added support for the analog input Resolution feature to control resolution, allowing decreased noise at the expense of speed.
Added control for Range and Resolution on LabJack_T7_AiSetup.adl.
Added LabJack_T4_AiSetup.adl to control Resolution on the T4. Range is not available on the T4.
Decreased the number drvModbusAsyn port drivers created for the T7 from 25 to 8, and for the T4 from 19 to 6.
Replaced multiple startup scripts (LabJack_T7_1.cmd, LabJack_T7_2.cmd, etc.) with a single LabJack_T7.cmd using environment variables.
Added generate_T7_2_and_3.subsititions.sh script that generates the subsititions files for modules 2 and 3 from LabJack_T7_1.substitutions.
Changed all .template files to be model-independent.
Removed the DATA_TYPE macro for all .template files. It is specified in the drvModbusAsynConfigure command for that driver.
Changed the bi records from using calcout records to select the bit, to using the mask parameter in asynUInt32Digital.
Added longin records for the FIO, CIO, EIO, and MIO binary inputs to the main T7 and T4 screens.
