can you help me ?
i am working in project based on FPGA kit and GSM
i have read the datasheet of GSM900 and i understood its ATcommands
But i don't know how to code it in VHDL
i knew i should have ascii code and shift register
could you show me the steps should i follow it
and if you have a sample code it would be better
 

A straightforward way could be to implement a small soft processor in FPGA and write the AT command handling in C language.

Of course it's possible in pure VHDL as well, but no fun particularly.

Some necessary steps:
- write the RX and TX UART code
- write a command state machine to send specific AT commands
- write a parser to decode the modem responses
- design high level interface that provides access to the supported modem operations and presents results

Hi,

Without further informations it is impossible to answer.

Where exactely is the problem?
What (answer) do you expect?

Maybe give additional information about your hardware, interface...
