5  Programming & Streaming 

The  EV-Kit  is  by  default  in  standalone 
mode. However, for some applications it is 
useful  to  evaluate  the  raw  data  of  the 
IQS127. To be able to use this feature, the 
IQS127  needs  to  be  in  streaming  mode. 

The  daughter  boards  can  be  programmed 
through the mother board. Begin by: 

 

Inserting 

the 

daughter 

board. 

(Remember to move R3 to R4) 

 

Move  slide  switch  S2  to  programming. 
See Figure 5.1
