View Source pmod_gps (grisp v2.8.0)
PmodGPS module.
The PmodGPS sends the GPS data over UART.
Start the driver with
1> grisp:add_device(uart, pmod_gps).
Summary
Functions
Get the GPS data.
Functions
-spec get(grisp_nmea:message_id()) -> {grisp_nmea:talker_id(), grisp_nmea:message_id(), map() | binary()} | undefined.
Get the GPS data.
The input parameter specifies which type of sentence to get. For a description of the sentences see the PmodGPS Reference Manual.
The sentence CRC is checked for all the sentence types, but for now only the
GGA values are parsed. If other sentences are needed, grisp_nmea
needs to be
extended to support more types.
