I have seen that this query has been asked previously but there was no answer to it.Therefore, I am raising the issue again here as follows: Currently, I am using INT1 for free fall detection which is already outlined in the AN3308 application note. ...

Going over the application note AN3308 (Pg:27), step 9 depicts that in order to detect event, for example, free-fall, poll INT1 pad. This means checking the the physical status of the MCU pin to which INT1 pin is connected. However, looking at the ex...

Has anyone implemented or does ST provides a library where the NDEF records can be appended or chained together for data logging such as long term sensor data etc without overwriting the old records? Looking at the current NDEF library of the ST25DV ...

First of all, apologies for asking too many questions on the forum. This is the only way I could get some feedback and suggestions as there is not a huge community around ST25DV.I have a custom sensor node connected to the ST25DV04K via the I2C inter...

Hi,I have just bought couple of brand new ST25DV64K chips and mounted them on ANT7-T-ST25DV04K board, replacing the 4K version with the 64K one.Then, I read the tag out with the NFC Tap APP and got PRODUCT_UNKNOWN on my screen as shown in the scree...

Unfortunately, I do not have the newer version. As you may have read from this thread, there was some missing features which I implemented for my own application and after that i hav not looked into the newer libraries this year. ST staff told me tha...

@ADale.1 ,The readers package is the NFC tag reader. Its been a a while that I was working on this, but you can download the c-library provided by ST for ST25DV from this page. It includes all the low-level implementation of the APIs that one may n...

Hi @Eleon BORLINI ,In order to detect events though LIS3DH interrupt pins, two of the main parameters are Threshold value (INTx_THS)INTx_DURATIONHowever, I am having a bit of difficulty in interpreting these values. How does the value for instance 0...

Thanks @Eleon BORLINI for clarifying my doubts. This makes life easier at my end.RegardsRajeev

After digging into the data sheet and the application note, I came up with the following parameter values. In particular, the SW routine that configures the device to detect shock events and to signal them is the following: 1. Write 77h into CTRL_REG...
