arduinotonesampler's Issues

Try to map Input Voltages to Tone Pitch for Piezo Speaker

Make class for every led module

• change sendWord and sendByte to Functions

• StepLight class

  • stores state of Steps- and Sites- LEDSs
  • showStep-Method
  • changeStepQty-Method

• ToneLight class

  • stores state of Tones- and Octave- LEDs
  • determineToneLight-Method
  • showNote-Method
  • createToneData-Method

• ModeLight class

  • stores state of Mode LEDs

Show Tone Pitch with LEDs that are connected over a ShiftRegister

Test Shift Register Control via SPI

Implement Step LEDs

• use timer interrupts for non blocking step clock
  https://github.com/khoih-prog/TimerInterrupt

Implement Startup Sequence for all LEDs

• only Red Mode LEDs are missing now

Sound jumps back and forth with some control voltages

Test Tone Arduino Library with Piezo Speaker

Implement Input Shift Register SN74HC165N or 166N via SPI

• receive data via spi by sending dummy data
  https://forum.arduino.cc/t/how-to-receive-data-via-spi/251768

Improve LED Logic

• above LEDs should show which note is played (green)
• the row underneath show the 16 steps
  • LEDs should be normally on if they are selected steps (blue) (range between 0 - 32)
  • the current step LED should be off to show the current step

Map Voltage of Arturia Keystep to Notes for Piezo Speaker

• Measure Output Voltage of Arturia Keystep (CV-Pitch)
• Map Voltage of Arturia Keystep to Notes
• A class?

Make Speed adjustable

A rotary encoder should be able to adjust the speed

Add Site LEDs to Startup Sequence

Test different Input Voltages with Voltage Divider and Buttons

Implement Tone LEDs with Oct

other leds should show the octave

Implement Modes

• Direct Mode: Play and show notes directly while cv-signals are incoming
• Arp Sample Mode: a falling gate will store the actual note and go a step further
• Play Mode: Play the stored notes
• LEDs with different color near the mode buttons should show in which mode the device is (red leds)

Implement Software I2S for DAC PCM5102A

Arduino UNO is too slow for this:
