Hello, I'm trying to get 8-bit real values from the katADC yellow block in Simulink. I was wondering why the block outputs fixed 8.7 bit values instead? I found the following explanation on one of the CASPER wikis but I'm still confused.
"The ADC block converts analog inputs to digital outputs. Every clock cycle, the inputs are sampled and digitized to 8 bit binary point numbers in the range of -1 to 1 and are then output by the ADC. This is achieved through the use of two's-compliment representation with the binary point placed after the seven least significant bits. This means we can represent numbers from -128/128 through to 127/128 including the number 0. Simulink represents such numbers with a fix_8_7 moniker. " Does it make sense to use a reinterpret block to convert it back to 8-bits? Thanks, Molly -- You received this message because you are subscribed to the Google Groups "[email protected]" group.
