I understand the concept of reading the voltage of the h-bridge capacitor as it is outlined in the "NFC passive lock implementation with NAC1080", what I am trying to understand is how to actually get the value of the variable "shc_channel_ma" for use in the following line of code.

cmp = shc_compare(shc_channel_ma, VOLTAGE_ON);

I have tried to get more insight with the doxygen documentation but am having trouble getting that to operate well and doesn't look like it will bring me closer to solving the problem.

Hi,

As mentioned in NFC passive lock implementation with NAC1080 AppNote shc_compare function is available in the SDK NVM library.

shc_channel_ma is an enum value and equals 3. Please look at shc_lib.h in the FW SDK to access this value.

Thanks,
Ajeeth
