I need to use the energy collection mode of ST25 to wake up L4. The software used now is En.X-Cub-NFC7. How can I modify the example code to set L4 to low power mode and wake up L4 only through the energy of ST25?
Why do I rewrite the code according to the example of nfc07a1, but the string of smartag is always read out? Can I change its code? void MX_NFC7_NDEF_URI_Init(void){
SmarTag_LED_GREEN_On();
while( SMARTAG1_NFCTAG_Init(SMARTAG1_NFCTAG_INSTANCE) !=...
I'm using FP-SNS-SMARTAG1, but I can't write strings correctly with code, and I can't write anything, what should I do? while (1)
{
/* Wake Up due to RTC timer */
if(WakeUpTimerInterrupt) {
WakeUpTimerInterrupt =0;
WakeUpTimerCa...
I need to write a specific string to the ST25 tag, but I don't see the use of NFC07A1_NFCTAG_WriteData. What should I do so that the string is written to the tag's address correctly and can be read by NFC?/**
* @brief Writes data in the nfctag at ...
Currently, only smartag_WriteData is downloaded from ST official installation package, but I need to store NDEF data, I have noticed that NFC07A1 has NfcTag_WriteNDEF, then how should I add NDEF read/write function in FP-SNS-SMARTAG1?
Hi @Brian TIDAL I know the Capability Container starting at block 0 followed by an NDEF TLV, I change the write address to 0XD1, which is block 01:03 11 D1 01: NDEF TLV (T=03h, L=11h,), can the following corrected code write temperature data correct...
Hi @Brian TIDAL Thank you for your answer. According to the instructions of AN4911, I can only know the theoretical knowledge of NDEF, but I currently need to read the dynamic temperature data without code instructions, how should I deal with K_Tempe...
Hi @Brian TIDAL I tried using NfcTag_ WriteNDEF can display temperature data correctly in text form, but I am currently debugging STEVAL-SMARTAG1, and the code does not include NDEF related function definitions, only NFCTAG_ WriteData and NFCTAG_ Rea...
Hi @Brian TIDAL But what I am writing is sensor data, which is dynamic data. Can I follow the above reference? Is there a specific method for writing NFC into sensors?
Hi @SofLit I used the low power evaluation board STEVAL-SMARTAG1, and the main function for its reference code FP-SNS-SMARTAG1 was changed to the thermocouple sensor of max6675, whose code is given above.
