Voice recognition V3 with Train examples

Hi, can anyone tell me on the meanings of "uint8_t" ? I'm doing the research on Elechouse VR3 and I need the information of the settings on this module which are sampling frequency and Quantize bit. Thank you. I dun have an idea on how to find the preset sampling frequency and quantize bit for this module. Any suggestions from experts?

void printSystemSettings(uint8_t *buf, int len);

uint8_t is an unsigned 8 bit variable, also know as a byte

So should 8 bit consider as quantize bit ?

what does that mean?

I not sure the 8bit is referring to what

Do you understand that a byte has 8 bits, each of which can be 0 or 1, and hence a byte can hold a value between 0 (all bits 0) and 255 (all bits 1) ?

void printSystemSettings(uint8_t *buf, int len);(uint8_t *buf, int len);

is the prototype of a function named printSystemSettings() that requires parameters of a pointer to type uint8_t and int

What may be confusing you is that it is a function prototype and as such it does not call the function nor does it contain the code of the function. Its sole purpose is to tell the compiler that the function exists later in the code. Such prototypes are usually not needed in an Arduino sketch because the compiler/pre-processor creates them for you when the code is compiled
