SetFs7200
Function
Used to change the AFE sampling rate to 7.2 kHz. Initially Si3021 is initialized to
8 kHz sampling rate in
Init_Si3021
. This function must be called by the user appli-
cation when the data pump requests the user application to change the sampling rate
to 7.2 kHz.
Prototype
void SetFs7200(void)
Arguments
None.
Return Value
None.
Code Example
SetFs7200();
