Saving a Float to BKP Register

Hi,

I'm fairly new to the world of microcontrollers. I'm using the STM32F103ZG on the MCBSTM32E development board and am saving user-defined inputs to the BKP registers. Most inputs are positvie, small integers. However, I need to save a floating point input.

The BKP write function in the STM library, BKP_WriteBackupRegister, is configured to accept uint16_t and I'm pretty sure it's not as simple as creating a copy of that routine and declaring the Data parameter to be float.

What's the best way to save a float to a BKP register?

Thanks in advance,
Lisa
