byte operations

[skisim]

hi everybody 

I have   established  a comunication with serial port ..it sends strings in hex ..my problem is how to convert string in hex( 2 bytes) to perform this opeartion in order to extract numbers ( the string is composed by 2 bytes AxL and AxH)

acc=((axH<<8)|axL)/32768*16

Thanks for help

Use string-to-byte array function.

Hi skisim,

one (of many) possible solution:

I convert to I16 because of that scaling factor of 32768, which hints for signed 16 bit data…
