input capture mode timer interrupt

hello everyonehow can I generate an event when timer operates in input capture mode the counter value goes above the ARR register value? in my special case I load ARR value to 10000 and CNT register goes ablove ARR value and dosent generate an interr...

Can we anyone tell me that how to write code for I2C IO Expander in STM32F412

Can STM32 chips use any pin?

Coming from AVR this is not possible, I do see some peripherals can use multiple pins. Working with the STM32H7 specifically here. A colleague of mine said he was under the impression ST chips can use any pin ( or a number of pins ) for say one of th...

Can Anyone guide me in detail how to Measure AC signal 3V, 50Hz using STM32?? I have to find out the RMS value. Since I am new to this can you guide me how to go about ??

I have understood that I have to use Timer to trigger ADC conversion at a configurable sampling frequency. ADC Clock = 24 MHz. I am planning to use DMA also.Can someone help me with calculations and in detail explanation?

Issue to use PC13 as output on RTC wakeup timer

hello all, I want to write a code to test the possibility to use PC13 as output to activate a regulator when the micro is in Vbat mode.. I'm using a STM32F476.in the manual, in Vbat mode, RTC_OUT still available for Alarm ou wakeup output.so, in cube...

[Errata] Pin PC13 is not released when RTC_OUT is remapped to PB2

Some time ago I had this issue in a project with STM32L433CCU6:// Calibration clock output #if 0 // Warning! PC13 is switched to output mode even with OSEL = 00b RTC->OR = RTC_OR_OUT_RMP; // Remap RTC_CALIB from PC13 to PB2 RTC->CR |= RTC_CR_COE |...

regarding storage of values in last two bytes in an array

Hello Folks,I have connected my STML011G4U7 with ISO7816. In my code I am parsing ATR which is an 8 byte array and sending it. Here I need to measure the voltage from ADC which would be (3.3 V) and store it in the last two bytes of an array. How will...
