Description: gps1_5.c begins by opening a file gpsData.txt which will save all GPS message strings in ASCII. Next, the serial port is opened using a function prototype comm_setting() which invokes functions found in the IBMCOM library.
A while loop is entered, where the statement charRead = com_rx() serially reads a character and checks if it begins with a dollar sign. If so, this indicates a new GPS message string has been received and more characters are read until a carriage return (CR) is found.
tempString holds the GPS message string that was serially read. If it is a $GPGGA message, additional reading is done, where we know that commas separate geospatial data. sscanf is used to extract numerical data from the ASCII characters.
- [gpgga] - GPGGA statement accepted VC procedure, i
- [gps] - I graduated from the subject of design,
- [gps_PARSE] - gps protocol analysis (Kay Lide internal
- [GPSINSintegration] - INS and GPS integration Algorithms
- [sscanf] - the usage of sscanf is not known. Very u
