Hello, I'm trying to write an I2C slave using HAL which can accept variable length packet sizes.  I know this question has been asked before but haven't seen any solutions yet! 

The master can send data packets of variable length - all the HAL I2C methods seem to need a 'length' parameter. 

Has anyone found a solution to this?
