Hi, We can provide you a design solution based on a PIC with VS1011 mp3 decoder. IC. Hoping for your reply. Regards, Geo

Hello, electronic enginneer available. please check PMB for details

consider it done . !!! check pm.

Hi Dear, We are a dynamic Engineering concern of experts in embedded systems, programming, electronics and signal processing. Our application areas include smart metering, bio-medical equipment, aerospace and aviation industry and industrial automation. I have read the details of your project and happy to learn that I can help you in your efforts. We did a similar project with ATMEGA64 + SD card and W5100 (ethernet). The SD card was interfaced and FAT system was implemented to read/write from the SD. Your project would definitely involve read operations from the SD and then sending the data streams to decoder chip. I have the following implementation and cost proposal for the project. 1) I would charge US$ 600 for the overall project. a) This would include 2 working prototypes of the project. b) Schematics c) PCB layout and Fabrication. d) Parts sourcing and stuffing on the PCB. e) Firmware development in C (for either PIC or AVR MCU). f) Testing, debugging and porting the code on MCU. g) Online demonstration on SKYPE or other messenger. Please note that Shipment cost (if required) to the Employer (your) side is not included in the budget. If you have any queries pl feel free to ask. Kind Regards Ch
