Hello everyone,I'm facing an issue establishing an NFC connection via mailbox between my iPhone and a device that uses the ST25DV04K chip. The application works perfectly on Android devices, but I'm unable to achieve the same result on iPhones.Detail...
Hi,In the RFAL library I see that the global variable st25r3916interrupt.status is protected using platformProtectST25RIrqStatus() while writing to this global variable. While reading st25r3916interrupt.status I see that it is not protected using pla...
Hi,as part of an upgrade to a number of products, we are looking at integrating 13.56MHz RFID capabilities into a number of products. Some require only to read an RFID card and others need to read and write such RFID card (no mobile devices or anythi...
我目前正在从事一个需要使用 STM32F103C8T6 微控制器和标准库进行代码编写的项目。在此过程中，我遇到了 ANT7-T-ST25DV64KC 芯片初始化的问题，一直卡在“while （！I2C_CheckEvent（I2C2， I2C_EVENT_MASTER_MODE_SELECT））;在此步骤中，我还对读取 I2C_SS0_Dyn 数据感到困惑。读出的数据永远是我在 read 函数中写的 slave 地址，有时读出的数据会增加 1。这是我的代码 无效 ST25DV_Init（void...
We use STM32F103C8T6 as the main control chip, ST25DV64KC to do the slave and ST25R3911B NFC communication project process, we found that we are very confused about the initialization of ANT7-T-ST25DV64KC, we have been initializing failure in the pro...
Hello, So I am trying to make my freshly bought ST25DV64KC- DISCO work.I was trying to run the firmware update with NFC connectivity with the iOS NFC tap application.It was not working, since for the firmware update demo with FTM, kept complaining ab...
