Arduino_To_WinDaq Chart Recorder

Originated from our DI-188, this open source project turns any Arduino® (Arduino Zero is used here) or Arduino®-compatible module such as DI-188 to a WinDaq-based data acquisition chart recorder. It supports up to 16 analog channels (4 analog channels is demonstrated in the source codes) to accept readings from on-board ADC or sensors connected to grove connectors. It supports WinDaq addons like FFT, Spectrogram, Smart Meters, Gauge display, various trigger modes, calculated channel, XY plot, and Excel link,

To use the project:

1. Please follow this instruction to install Arduino IDE 2.0.
2. If you don't use DI-188, which is based on Seeeduino XIAO, jump to step 3)
   • Follow this instruction to allow XIAO to be added to Arduino IDE search engine
   • Restart Arduino IDE to allow XIAO to be added to the search engine
   • From ArduinoIDE->Tools->Boards->Board Manager, type in XIAO or Arduino Zero and let IDE download all libraries for your module
     • When you upgrade Arduino IDE, you may need to upgrade the libraries as well
   • Select ArduinoIDE->Tools->Boards->Seeed SAMD boards->Seeeduino XIAO
   • You may also need to specify the COM port for the module
3. Install Flash library
   • Visit https://github.com/cmaglie/FlashStorage
   • Push Code button and select Download ZIP
   • From Arduino IDE, follow ArduinoIDE->Sketch->Include Library->Add ZIP Library... to add the downloaded library from above step
4. Download the source from above (press the button <> Code and download ZIP file
5. Copy the file folders inside the source ZIP file to your arduino IDE's file folder (default folder is ThisPC->Documents->Arduino)
6. Restart Arduino IDE
7. From Arduino IDE, use File->Open... to open a project
8. Make sure Arduino IDE->Tools->Boards points to Seeed SAM boards->Seeeduino XIAO
9. Now you can compile and upload the firmware
10. To download WinDaq, please click www.dataq.com. WinDaq is a proprietary commercial software from DATAQ, and it allows free personal home use only under this Arduino project.
11. Only the XIAO_WINDAQ base project is maintained regulary. If you have trouble using the other sketches, please compare it with base

DI-188 Projects to interface with various sensors and other applications

1. 3-axis digital accelerometer LIS3DHTR (See demo screen shot below)
   • Range: +/-2,4,8,16G
   • The source is included in the base project
   • Visit https://github.com/Seeed-Studio/Seeed_Arduino_LIS3DHTR
   • Push Code button and select Download ZIP
   • From Arduino IED, follow ArduinoIDE->Sketch->Include Library->Add ZIP Library... to add the downloaded library from above step
   • In the sketch, uncomment INCLUDE_3DACC to use it.
   • LIS3DHTR module should be conneced to a I2C port of DI-188
2. Environmental temperature and humidity sensor (DHT11)
   • Range: 0 to 50C +/-2C, 20 to 90%RH+/-5%RH
   • The source can be found in xiao_windaq-dht
   • Visit https://github.com/adafruit/DHT-sensor-library
   • Push Code button and select Download ZIP
   • From Arduino IED, follow ArduinoIDE->Sketch->Include Library->Add ZIP Library... to add the downloaded library from above step
   • DHT11 module should be connected to the DIG port of DI-188
3. Environmental temperature and Air Pressure Sensor (DSP310)
   • Range: -40 to 85 C +/-0.5C, 300 to 1200 hPa +/-1hPa
   • The source can be found in xiao_windaq-dsp310

   • Push Code button and select Download ZIP
   • From Arduino IED, follow ArduinoIDE->Sketch->Include Library->Add ZIP Library... to add the downloaded library from above step
   • DPS module should be connected to a I2C port of DI-188
4. DI-188, along with this open source project, is now supported by a turn-key software package to facilitate the study of seismological concepts in middle school through introductory undergraduate classrooms
   • Download and run the software from https://www.iris.edu/hq/inclass/software-web-app/jamaseis
5. Higher speed version
   • The source is included in the base project
   • Uncomment #define HISPEED
   • The burst rate will be raised to 20K s/s, but resolution will be lowered to 9 bit due to noise in ADC
6. Higher resolution version
   • The source is included in the base project
   • Uncomment #define HIRES
   • The resolution will be increased to 14 bit, but the max throughput rate will be lowered to 100s/s

Calibration of DI-188 DI-188 is shipped with nominal calibration. If you want a better reading, please check out this calibration utility

Warning: the input voltage for plain Arduino® modules is limited to only 0-3V! Need industry-grade front end of +/-10V range (30V Max) with 1MΩ input impedance? Please consider our XIAO-based starter kit DI-188
