I work for a company called Spinnaker International, we are UK based. Our website is as follows:-
I have been accepted by the NXP docstore NDA procedure and I have been able to download AN11350. I am only interested in the signature verification function of NTag21x tags. I am using a Microchip PIC24FJ128GB204 microcontroller, I can get the AN11350 8 bit libraries to compile in my 16 bit IDE but I cannot get the ECDSA verify function to give the correct reply even though I am giving it the correct input. Could you please help?
