Nathan Ewin / Mbed 2 deprecated UM6_IMU_AHRS_edit_NJE

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.

lhiggs 0:03c649c76388 29 This example shows how to use the new callback system. In the old system
lhiggs 0:03c649c76388 30 Mbed's FunctionPointer[1] type was used to store abd make calls to callbacks.
lhiggs 0:03c649c76388 31 However, that limits the callback function prototype to void func(void);
lhiggs 0:03c649c76388 32 which means we cannot pass parameters.
lhiggs 0:03c649c76388 33
lhiggs 0:03c649c76388 34 This latest version of MODSERIAL now uses its own callback object. This allows
lhiggs 0:03c649c76388 35 the passing of a pointer to a class that holds information about the MODSERIAL
lhiggs 0:03c649c76388 36 object making the callback. As of version 1.18 one critcal piece of information
lhiggs 0:03c649c76388 37 is passed, a pointer to the MODSERIAL object. This allows callbacks to use the
lhiggs 0:03c649c76388 38 MODSERIAL functions and data.
lhiggs 0:03c649c76388 39
lhiggs 0:03c649c76388 40 Additionally, since MODSERIAL and the callback parameter class MODSERIAL_IRQ_INFO
lhiggs 0:03c649c76388 41 are friends, MODSERIAL_IRQ_INFO can access the protected functions of MODSERIAL.
lhiggs 0:03c649c76388 42 This is used to ensure functions that can only be called during a callback
lhiggs 0:03c649c76388 43 can be invoked from a callback.
