Trying to log data from UM6 sensor with GPS receiver LS20031. I have two problems: - I can't log to file at a fast rate (<0.5s) without data values freezing to a fixed value. Print to pc screen it works fine. Ideally I would do this with an interrupt (e.g. ticker) so that the time of each reading is a fixed interval - I removed this as I thought this was causing the problem. - I want to record GPS lat and long. I have setup the GPS ground speed so I know the sensor are communicating. So I possibly havent set the config file to correctly interpet these two signals.

Dependencies:   MODSERIAL mbed
