I need a code written in embedded C for atmega 128 . Freelancers are free to choose SPI chipset of their choice but they have to keep in mind that the SPI chip should have storage capacity of atleast 1mb and should have good performance ( obviously cost should be as low as possible). The code needs to perform the following: Write this string "868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136" in SPI with atmega128 and then read back line by line. It should be easy to read strings and write string. Once read the line should be deleted.I would prefer FIFO for reading strings but if you can't do that then it won't be much of a problem. There can be multiple lines like this. One MB is enough. Example(write) 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 Read(first in first out) 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136 Freelancers please note that full payment won't be done until and unless the code is checked !!

Hi Sir, I work with ATMEGAxxxx for few years. There is no microcontroller with this huge internal memory, you need tot use an external flash memory like AT45DB161E (16 Mbit = 2 Mbytes). If you choose me, I can quicly design a pcb with ATMEGA328p (for example) and the flash memory, C code source for memory access and all functions you need for write, read, verify the flash. (micro + flash ~ 4 euro cost, for low qtys) (p.s. your sample writting "868182009724946,03/19/2013!12:17:52,29.1741,75.7049,294,0,23,1136,1136" is no so relevant once the string is the same in all writtings / readings)
