Requirements:
- audio noise generator (schematics: [url removed, login to view])
- ON/OFF by tact-switch
- OFF state = sleep mode of microcontroller (minimal possible current)
- VOLUME UP/DOWN function by tact-switch @ ON state
- VOLUME UP/DOWN = hold tact-switch @ time>1s (first hold tact-switch => UP, second hold tact-switch => DOWN, etc.)
- we need 10-16 steps of VOLUME control
- spectrum of audio noise can not changed in function of VOLUME
- last settings of VOLUME must be stored in FLASH (not protected block)
- watchdog must be properly implemented
- code must be tested on target hardware by Contractor (no theoretical work!)
- FLASH must be protected (excluded block of settings)
Contractor provide audio file with recorded noise (for each step of VOLUME).
After verification of quality of audio noise by Buyer, the Contractor will send source and binary codes.
After verification of codes, Buyer will release the full final payment.
