Changelog
07-02-2021	Release V1.0

09-15-2021	V1.25
- Added output amplitude adjustment per direction in SMC mode
- New stages support

07-14-2022        V1.27
- Add analog In mode in open loop in D-Sub mode and SMC mode, when the input range of analog In signal is from 1V to 10V, representing with output forward amplitude 10% to 100% with 1x for Gain and 0 for offset, when the input range of analog In signal is from -1V to -10V, representing with output backward amplitude 10% to 100% with 1x for Gain and 0 for offset. The type of trigger edge to start the conversion can also be defined.
- Support the D-Sub stage without encoder
- Support 3-Axis USB joysticks
- Config the knob of joystick in Daisy-Chain mode

09-27-2022        V1.28
- Improve PD2 stage movement below 10Khz
- Fix the waveform output bug in SMC CH1

05-23-2023        V1.31
- Fix the communication error when in daisy-chain mode
- Fix the home fail error when the stage moves to the limit position
07-27-2023      V1.34
- Support new encoder for D-Sub stages;
- Optimize position cleared to zero algorithm of the stages; 
- Optimization for some PDXR1 stages searching home position;
- Support fast return when the stage was out of target position in closed loop.
- Expanded the Analog in gain range for PDXR1;
-fix the bug when the firmware upgraded from V1.28 to V1.31 or above, the SN will be missed
-Add the position range limit of the stage displayed when the controller powered on. 
-Set PID Kd parameter limit>=0;
Notice: Please restore to factory setting after the firmware upgraded from V1.28! 
10-25-2023      V1.36
-Enhanced anti-jamming capability in searching Home peration, If the customer experiences Home fail In older versions firmware, please upgrade to version V1.36.
-Read Pid parameter from custom set in the controller or the eeprom of the stage;
-add warning “MOVE ABNORMAL” in open loop mode when the stage was stuck out of travel range;  
02-18-2024      V1.37
-New option for the stage will return the previous position after a power cycle;
-Fix the Pid parameters bug after load factory setting and save all parameters;
-Fix the controller will be disconnected in Daisy-chain mode;
