Hi there, if you want another frequency, you'll have to use another LC-combination. The datasheet and evaluation kit should give you enough info on how to do that.
Thanks for the answer, when I have an xyz antenna can I use one plane (x for example) for 134khz and the other for 125khz? Regards
Hi, The AS3933 was not designed for detecting two frequencies simultaneously. You could pull it off, but you would need to set the registers correct for either 125kHz of 134kHz beforehand. I suggest you try with a single frequency first and build it from that point onwards.
Hi, I have an antenna tuned to 125khz, the capacitor values are the same as in the datasheet, I want to be able to change the mode from 125khz to 134khz using a button connected to Arduino, I tried to achieve it with "asTag.begin(134000)", but without success, the value I achieve is 128khz according to your function for antenna tuning. Regards
Hi, I am using your pcb and the same components, how to tune the antenna to 134khz?
