void ms5611_i2c_periodic_check ( struct Ms5611_I2c ms)

Periodic function to ensure proper delay after triggering reset or conversion.

Should run at 100Hz max. Typical conversion time is 8.22ms at max resolution.

convenience function to trigger new measurement.

(or start configuration if not already initialized) Still need to regularly run ms5611_i2c_periodic_check to complete the measurement.
