I'm trying to establish communication - FTM between ST25R3911B and ST25DV64KC . I'm running the example program in the reader module and I have enabled the mailbox in the dynamic tag side. The reader is able to detect the dynamic tag and is trying t...
We are using STM32L053R8.What is the best method (Clock and Low power modes) to achieve lowest power consumption while taking ADC reading every one second? Also whether to use RTC or LPTIM or combination of both to wakeup the device from the Low Pow...
I tried using the sleep mode in STM32L053R8, it gets stuck in this condition. what is the reason. if((ulpbit != 0) && (vrefinbit != 0)){SET_BIT(PWR->CR, PWR_CR_ULP);}
What about a 32MHz system clock and required frequency as 4KHz? Is there any rules in defining the PRE and ARR combination? I know that if the ARR register is 16bits, then the maximum value is 65535. anything else other than that
One more thing. The Calibration value shows 666 and 849 for 30°C and 110°C respectively. But when I tried to read it using the inbuilt ADC channel the value shows 680 for 25°C. What may be the reason?
