Characteristics of the Master module

The form “Master” connects to a USB port (USB1, USB2 or usb3), provides some generic Pin InOut (6, 10 or 12 Depending on the version) and a serial transmission line, toward the Slave modules.

The connector “USB” can be connected to one or two USB ports, to draw a current of 500mA or 1A. The connector “Serial Line to slaves” It is normally connected to the serial line that goes to the slave modules with 3 wires (GND/+ 5V/Data). The fourth pole (Dir) It was designed to connect the device “Master_iso”, optical isolation. It is now used as Pin 10 and isolation, If necessary, with commercial USB isolators. In the latest versions there are also pins 11 and 12.

The Pins 7, 8 and 9 are special, they are the only ones that tolerate input signals from zero to five volts.

And’ also possible to connect more than one Master, with USB and separate transmission lines, in order to increase the possibilities of connection. You can, for example,, use a high-speed communication line, for devices that require a quick refreshment and a second line of communication, slower, for all other.

In This video you see some Master flying machines in China.

Master connectors from V4 onwards
With the new Master, version 4.0, the pins are all marked with a circle and number.

Connectors
On printed circuit boards (PCBs V3 onwards), screw connectors were replaced with male-female extension cables connectors. These connectors look less professional, but they are comfortable and reliable. (Screw connectors require a very small screwdriver, It was necessary to tighten them without too much force, to avoid damaging the screw, But if the force was little, with time it became loose. With new connectors instead, connections are fast and safe)
In later versions the connectors are all male and using female-female connector cables.

Voltages and currents
Input-Output pins work with analog signals from 0V to 3.3 V. About connectors is available 5V voltage and a voltage of 3.3 volts stabilized, useful for some sensors. The maximum current for the pins are configured as Output is +/-15mA. For those that are configured as Input you have to limit the voltage from -0.3 Volts to +3.6 Volts and not exceed these thresholds, with currents greater than +/-100uA. Special pins 7, 8 and 9 also accept signals from 5 Volts. (see technical/pin-types For more information about voltages and currents)

Transient errors caused by surges on Input pins
Sometimes, touching the pins with your fingers, the HAL program stops communicating with hardware, writes a red line with the message "disconnected" and you have to press "Recognize". This will occur if the body is charged with static electricity and emits a small electric shock. All components are carefully chosen and never break, But even if you don't see the spark, It's always tension of many thousands of Volts, who send haywire temporarily serial communication and USB port. During the tests we take special care to handle forms only from off, or touch before the mass (for example the USB connector). The final project should always provide an insulated container that prevents users from touching metal parts under voltage.


Slave module characteristics “Capsensor HQ – V3”

This slave measures the distance of a conductive object (typically a hand). In the range of distances from a few centimetres to several metres provides performance unattainable with any other tracking system.

CapSensor V4

Unlike ultrasound sensors tracking is always progressive, cannot in any way “Skip” from a distance at the other, due to the reflections of the signal or detection of multiple obstacles. The detection is always stable and precise with a rapid response time, in the order of milliseconds..

The CapSensorHQ is perfect for controlling with hand in a linear fashion and always soft sounds and videos features, which Waveform (WAV, MP3, etc.) and movies/music video (AVI, mpg, MP4, etc.)

Since September 2012 version available: 3 of CapSensor (visible in this photo) with improved stability characteristics. Here too the screw connectors were replaced with male-female extension cables connectors. These connectors are less beautiful to look at but they are comfortable and reliable.

Features

  • Measurable range of capacity: from 0.001 PF to 10 pF
  • Resolution: one thousandth of pF
  • Stability: around the thousandth of pF
  • Small object detection (a hand): up to a few meters
  • Large object detection (an automobile): up to ten meters
  • Precision and stability on distance detected: from a few mm to a few tens of cm
  • Sensor size vary between square centimetre per one square meter

Technology
A low noise FET analog-to-digital conversion 24 bits provide extreme sensitivity in the capacity measure very small.

Slave module characteristics “Servant”

SERVO modules are no longer used, instead of using the Masters that have many advantages.

  • 12 Pin instead 10
  • Safer communication (there is no serial which sometimes stops)
  • Configurable pins with many types that are missing in Servos

We leave the following information for reference only
for those wishing to build them and possibly improve them.
