ST95HF Error Codes

Hi Guys,

I got problems in the calibration-process (same routine like in the ST95HF Eval Firmware). I should get Responses of the ST95HF like ''0x00 0x01 0x01'' or ''0x00 0x01 0x02'' to get the DAC Data High border. But instead the Repsonses I should get, I get ''0x00 0x01 0x80''. The Datasheet says something like that to the Error Code 0x80:

EFrameRecvOK

Frame correctly received (additionally see

CRC/Parity information)

But that really doesn't help me. I also get sometimes the Error Code 0x82. Is there an application note, which recommends what o do with the different error codes? Thanks a lot! #st95hf-cr95hf-95hf-error-codes

Hello,

do you check forst the communication with ST95HF What is the sent command ? have look below to the flow of a correct Tag calibration  seqence
