  • I'm having issues getting the SI4721 to find the chip during the TestSI4721 and TransmitSI4721 sketches. I've noticed that Matthias Hertel's updated transmitter library has " #include <si4721.h> but the file is called <SI4721.h> " (capital letters). Even after I change it, I'm getting the "Device NOT found at address 17" error, which doesn't make sense because its address should be set at 0x11 (hex for 17) and works at that address for the ScanRadio sketch. I've changed the address to 0x63 just to check, didn't work. What am I missing? It seems that the sample code is not initializing the chip?

No public wish lists :(
