" Hex " and " binary " are two different concepts. This looks like a big-endian float; just reverse the order of the bytes, and treat the memory as a float. And what do you mean with "inverse"?

Could somebody inform me what the maximum current that a MSP430 launchpad can handle is? I want to power it from an external source that provides 10mA of current. Would that be too much?

Hi Harish! You could, for example, use a function like this: float hex_to_float( uint8_t * hex_array ); uint8_t float_in_hex[4] = { 0x43, 0xCf, 0x80, 0x00 }; float float_from_hex; ... void main( void )...

What do you mean by "sync problem"? If your microcontroller is the master on the SPI bus he controls everything, so I do not see a requirement for any synchronization. I'm not familiar with the device...
