Subject: [oc] SMS controller using FPGA
I am designing a system that would interface an FPGA to a nokia 7110
cellphone through a UART. I am planning to incorporate a feature that
would allow the FPGA to send SMS messages using AT commands. I am
at a quandary on how to effectively implement this process. Below is
and example of an AT command that I would use:
AT+CMGF=1 (carriage return) -- in ascii bit equivalent
Since each character would correspond to 1 byte, I would have to 8
bytes 9 bytes of data to my uart one after the other. My data bus going
to the UART is 8 bits. My problem is how to transmit this data
synchronously through a bus that is 8 bits in length. Can anyone provide
me a simple code that could do that?
