Requirements: - audio noise generator (schematics: [login to view URL]) - 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 EEPROM - watchdog must be properly implemented - code must be tested on target hardware by Contractor (no theoretical work!) 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.

I do have this PIC16F688 in stock so can easily build a test setup and code the firmware. I will make it ready in 7 days.

Hi, I can make the code you need. However, I don't currently have that particular PIC, so I'd need to order it first (that's why I state 10 days, and not 2). I'm about to place an order to digikey for another project, so I can include this PIC there. The code itself is not complex. Besides the PIC you'll need some sort of DAC, which can be something as simple as a resistor ladder. If you require, I can help you with that too. Regards, Guillermo

I understand your project, I reviewed your schematic and I can do the job for you. I have experience with the 16F688 I have made a couple of projects with it (you can see my reviews). In order to complete your project you must specify only 2 things: 1. The exact model of the speaker you wish to use, so I can make tests and recordings with it 2. Do you need some pattern or "wave" or loop or just random noise?
