Dear Sirs,We use ST25R3916 for our reader and want to adjust output power (0x28). We use RFAL library, could you tell me how to change the antenna driver output register (0x28)with the RFAL library, which function or variable should be used for the...
Dear Sirs,To achieve a longer reading distance, we are tuning the antenna matching parameters.To use the ST25R antenna matching tool, we need to give a value fortarget matching Z and target antenna Q. I wonder how to select the target matching Z for ...
Dear Sir,There is a question about argument VL53L1X_CalibrateXtalk().For cross talk calibration, we will use VL53L1X_CalibrateXtalk() with argument of uint16_t TargetDistInMm,we should give Xtalk calibration distance to the argument. But, we wond...
Dear Sir,
We are currently in the process of conducting crosstalk calibration using the VL53L1X ultra-lite driver, but unfortunately, the results we're obtaining are not as expected. Our approach involves utilizing an A4-sized gray chart board as the...
Dear Sir,I am using the RFAL driver and I would like to achieve reading multiple ISO15693 tags. How can I obtain the UID of multiple tags with RFAL driver? thank you very much in advance.Best regardsDai Sai
Dear Ulysses, thank you very much for your information.I found the initial value setting is 0. We will use thefunction, if we modify the value. best regardsDai Sai.
Dear TravisThank you very much for your information.We will do the matching adjust based on your advice, andtry higher Q-Factor. At current stage, we got a distance for 30cm, while the volage rangeis about 13V. The simulation from ST25R Antenna Match...
Dear John E KVAMthank you very much for your advise about selecting cardboard.We will prepare the cardboard according to your information. Best regardsDai Sai
Dear Mr. Han,thank you very much for your helpful information.I will try to make calibration based on your guide for a better performance.best regardsDai Sai.
Dear Ulysses,Thank you very much for your great help.With your help, we realized multi tag access successfully. Up to 9 tags can be accessed in X-NUCLEO-NFC06A1 environment. I think 16 tags could be accessed in a larger antenna environment.best regar...
