AC Sensorizer sensorizes up to 8 sensors and interpolates its AIN-readings. The main target of this application are sensoric devices delivering not exactly 0 - 5 V, like pressure-, distance-, resistor-based sensors or softPots.

This is a preliminary beta-release.
Use and build at your own risk!
There will be major improvements in the GUI/HUI within the release of the next version. Though the code basis (ACSensorizer.c) won’t probably change that much... – audiocommander

• supports up to 8 sensors, code can be adapted to use more (eg with PIC18F4620)
• enable/disable single AINs
• slowdown: slows down the signal and increases the gaps between generated values
• assignable CH and Controller-Number
• sense-min: 10bit value, ignores every signal below
• sense-max: 10bit value, ignores every signal above
• sense-factor: used for signal interpolation... uses fast bitshifting or complex division depending on value
• AUTO-sense feature: auto-calibration of sensor, detect MIN/MAX by sensing automatically adapts sense-factor!
• scale from and scale to: scales the output value from/to
• invert signal
• pedal modes:
  • filter ⇒ only forward if pedal down;
  • panic ⇒ send panic on release pedal;
  • combinations of all pedal mode options are possible
• detect release: send 0-value if signal drops below sense-min
• bankstick support: 1 connected bankstick provides 2 banks with 127 patches each
• midi configurable: full configuration possible with NRPN-messages
  • NRPN-MSB CC99 for sensorSelect / sysEx mode
  • NRPN-LSB CC98 for controlType
  • DataEntry MSB CC6 and LSB CC38 for controlValue
• LCD-Output (2×16 or -recommended- 4×20)
• HUI-Input to control up to 4 sensors with 8 switch-encoders, pedal, store- & panic-button in 2 modes (PLAY/SETUP)
• ACSim Console Debugger: code integrated and ready to use configured for XCode2
  • select “ACSim” as target and test the application via command-line
  • inspect variables with a (graphical) debugger (GDB support within XCode2)
  • visit http://www.midibox.org → there’s a tutorial how to use Code::Blocks

MBHP Modules:

• one MBHP_CORE module
• one MBHP_LCD module (5×20 optimized, 2×16 available)
• one MBHP_DIN module for
  • 8 Encoders (preferrably with):
  • 8 pushButtons
  • 1 mode-select switch
  • 1 pedal (optional)
  • 1 PANIC button (optional)
  • 1 STORE button (optional)
  • 1 UP & 1 DOWN button (optional)

Sensors:

• up to 8 (default: 4) sensors connected to unmuxed AIN (J5 of MBHP_CORE). Note that sensors 5 to 8 can only be configured via MIDI by sending NRPN-messages

• m5 sensorizer v 0.2.2 (416 kB), download from http://www.audiocommander.de
• readme.txt ...you should really read this, even if you’re not recompiling the software!

Compiling Notes

The application can be recompiled with a variety of strictly separated #define- options. For example setting SENSORIZER_INTERFACE_HUI to 0 compiles the application without hardware input controls and therefore reduces the file- and application space. Compiling without HUI, BANKSTICK, NRPN-Config and LCD generates code with approx. 3 or 4 pages; compiling with all options will result in an application file of approx. 12 to 14 pages.

All Sensorizer parameters can be controlled and set by sending NRPN messages by MIDI:

1. Send NRPN MSB (Controller# 99) to select control type
2. Send NRPN LSB (Controller# 98) to set the control parameter
3. Send NRPN Data MSB (Controller# 6) and NRPN Data LSB (Controller# 38) to set the parameter value
