Hi Rockson, For the autocalibration steps, the freqcount-library is used, which was designed for 16MHz Arduino uno. I think the autocalibration steps should work without modifications. To be honest, I spent quite some time adjusting my hardware to make this work. The parallel capacitors should be matched to your coil for parallel resonance on 125kHz. I think the problem was caused by my hardware. The parallel caps should be as close as possible to the coils. You'd better use the design of the evaluation kit as a start.
Thank you very much for your quick response. I will redo my hardware and test again as recommended.
Regards, Rockson.
Dear Christoph,
Greetings. Regarding the use of this great library, I read in one of the opened issues that you only tested it on 12MHz board. What I intend to do is to read data from the antenna reception into the MCU. I have been trying to modify the code to adapt to my board but I am unable to tune the antenna. The best frequency I am getting is [Frequency: 2057 ] and subsequently:
Testing bit: 4 Frequency: 2057 Testing bit: 3 Frequency: 3 Testing bit: 2 Frequency: 3 Testing bit: 1 Frequency: 3 Testing bit: 0 Frequency: 3 Calibration for antenna 1 fails
Can you please recommend to me a solution approach? Thank you for your time and have a blessed day.
Kind regards, Rockson.
