Like this flow,

Usage,

• Get buttons status.
  • reTerminal Buttons node will catch the button status when you push F1 / F2 / F3 / O buttons.
• Get accelerometer sensor status.
  • reTerminal Accelerometer node will catch the accelerometer sensor data.
• Get light sensor status.
  • reTerminal Light node will catch the light sensor data.
• Get touch position.
  • reTerminal Touch node will catch the touch position data when you touch the display.
• Turn STA LED to green.
  • reTerminal STA LED Green node will turn on green in reTerminal STA LED when inject node boolean true is clicked.
  • reTerminal STA LED Green node will turn off in reTerminal STA LED when inject node boolean false is clicked.
• Turn STA LED to red.
  • reTerminal STA LED Rreen node will turn on red in reTerminal STA LED when inject node boolean true is clicked.
  • reTerminal STA LED Rreen node will turn off in reTerminal STA LED when inject node boolean false is clicked.
• Turn USR LED to green.
  • reTerminal USR LED Green node will turn on green in reTerminal USR LED when inject node boolean true is clicked.
  • reTerminal USR LED Green node will turn off in reTerminal USR LED when inject node boolean false is clicked.
• Set buzzer.
  • reTerminal Buzzer node will turn on the reTerminal build-in buzzer when inject node boolean true is clicked.
  • reTerminal Buzzer node will turn off the reTerminal build-in buzzer when inject node boolean true is clicked.

Acknowledgments

The node uses npm package for reTerminal for easiry reTerminal device Data access.

This library is easy to access reTerminal device Datas such as buttons, buzzer, LED, light, touch positions and accelerometer sensor. Thanks!

History

• v0.1.3
  • Accelerometer sensor node shifted from getting using exec spawn to getting inner function.
  • Light sensor node shifted also the same approach.
  • And added a interval stop for them definitely when Node-RED closed.
• v0.1.2
  • Intervals getting data about accelerometer and light sensor changed 200 ms to 1000ms temporarily.
  • I will change them so that you can freely choose the interval in the near future.
• v0.1.1
  • Countermeasures about getting one over more lines at Buttons node.
• v0.1.0
  • Changed some node names bitly.
  • Light sensor supported.
  • Buzzer supported.
  • Touch Panel supported.
  • Updated a quick start flow accordingly.
• v0.0.5
  • Added a quick start flow.
• v0.0.3
  • Accelerometer sensor supported.
  • LED STA Green on/off supported.
  • LED STA Red on/off supported.
  • LED USR Green on/off supported.
• v0.0.1
  • First release.
  • Buttons supported.
