I need to interface an FTDI VNC2 chip with V2DAP firmware to AVR uC (MEGA and XMEGA) via SPI interface to read and write files in usb dongles. Source code is required with single functions to - Check if USB DONGLE is connected - Check firmware version - Read Dir Content - Move through Directories - Open a txt/binary file and read its content - Open a txt/binary file and append some content - Open a binary file for reading and read some block of data at a time to stream its content like in the following pseudocode example: unsigned char Buff[512]; return_code = openfile(&File, "[login to view URL]", READ); if ( return_code == OK ) { while ( !f_eof(&File) ) { return_code = f_read(&File, Buff, sizeof Buff, &br); if ( return_code != OK ) break; for ( unsigned char i = 0 ; i < br ; i++ ) { while ( <some condition from main program> ); <do something with Buff[i]> } } } Libraries should be contained in two files (.c .h) to be included in a main program. Libraries should be written for Atmel's MEGA or XMEGA uC. Comments should be present to describe every functions.

Hi, I can handle the library you are asking for, there is nothing particularly complicated beside annoying parsing asynchronous uart responses over nonstandard SPI. Your pseudo-code reflects POSIX like calls, is it for compatibility or for convenience to understand the code? One more thing - I will need a VNC2 protro module (V2DIP1-32 I guess) to debug with and it may take a couple days to order it from DigiKey, plus uncertain shipping because the holiday season started already. Regards, dsnejko

Dear hiring manager , • In these days I m working on single phase energy meter Using Maxim Integrated Teridian 71M6541 chip & CTs , with GSM module Fibocom G610 & Renesas R8C 5rf212BC to serially communicate b/w two & Renesas also communicate through uart with Teridian 71M6543 to request data from it. Rest experience is as follow : • Developed & Deliver Complete 16 bit Computer with external RAM ,ROM EEPRROM, Data-bus & 8086 Microprocessor for Military application. • Developed Power supply of 40 amperes ,intput 22 -28V, output volts 28V constant & UPS for Military application, with 24V 20 cells battery of 7Ah. • Work on different sensors Cross Wind Sensors , Atmospheric temp. charge Temp. • Develop Atmospheric temp. sensor ,measure atmospheric temp. • Develop Charge temperature Sensor , measure powder temp. using LM335 • Develop Tilt Sensor measures the Degrees of tilt of body , using SCA103T built in chip. • Develop angular velocity Sensor gives rotation of body , using YUMO E6B2-CWZ1X Rotor Pulse encoder • Designed Pressure Sensor Measure Atmospheric pressure using, MPX5100 sensor • Develop Wind Sensor gives direction & speed of wind using FS2 FLOW sensor & PIC18f26K80 Micro-controller , turn nonlinear output of FS2 to linear output • All Sensors are Military grades with high temperature range &strong mechanical structures • Wireless technology that I used Blue-tooth module HC06/HC05, ZigBee & ZigBee Pro , GSM Module. I m looking forward to your Kind response
