I'm working with ST25TV02KC-TFG3 in a tamper inlay. ReadConfiguration FID=03h, PID=06h returns the same value with the tamper contacts open or shorted. How should I be interpreting these results? The commands are being sent from a Feig CPR74 via thei...

Thomas, thank you for helping to sort that out for me. I missed the factory settings of 63h and 6Fh on page 24. A fresh inlay shows 30306Fh for TD_Status(03h,06h). So that's the SEAL event with the OPEN message. I think I can figure it out from h...

Posted on November 26, 2017 at 21:47Thanks, Clive, that did it!HAL_UART_Receive_IT() does seem to block. Here is my main loop: int loopCount = 0; GlFeigInit(&UartHandle); while (1) { loopCount += 1; HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1, (loopC...
