ADC self calibration
Hello,I am using STM32L471QE.Please tell me how to calculate CALFACT_S and use it for ADC self calibration.I confirm that ADC1_CALFACT in CALFACT_S is 0x3A or 0x3B.I want to know how much [CALFACT_S] affects accuracy.Please let me know if there is ...
Resolved! GPIO output is running slower than clock frequency
HiI'm trying out stm32h743 now, and try to make output signal from GPIO.I've set same frequency on F429 & H743 with same code. However, The the signal much slower(longer) in H743.F429 400nsH743 4000ns (well... my purpose is to shorten the l...
Resolved! Synchronize Timer 1 and Timer 8 on STM32F446RE
Hi,I'd like to run synchronous PWMs on TIM1 and TIM8 of an STM32F446RE. I use TIM2 to trigger both timers.My setup:Master: TIM2MSM bit is setTRGO = Enable bit (CNT_EN)Slaves: TIM1 and TIM8Slave mode = Reset modeTrigger source = ITR1I appended my Cube...
STM32F429 bank swap for OTA update
HiFor a project I am using a STM32F429ZITx and need to implement OTA functionality. With single bank chips I have previously put the update into the free part of the flash, then copied it over and restarted.With 2 banks I came as far as erasing the u...
Resolved! Simple question about setting ADC's analog watchdog thresholds on NUCLEO-STM32F746ZG
The reference manual (link below) gives some details regarding setting the high and low voltage thresholds for the ADC's analog watchdog in the ADC_HTR and ADC_LTR registers. However, I can't find any details explaining how the values put into bits [...
STM32H755ZI SPI / Proper way to receive data
Hi everyoneI'm currently working with the STM32H755ZI SPI1 peripheral. I'm using low level driver to read 2 bytes of data. I'm transmitting 2 dummy data bytes (0xFF) in order to get some response from the SPI slaves. Most of the time, the receive wor...
Hi i am using nucleo L073Rz board , how do we authenticate a user application bin file flashed in to a board from iap is the correct bin and move on to run.
The problem is crc used in iap for transferring the bin file is to only check for errors during the transfer process , however i dont want any random bin files to be flashed into the flash or executed from it, only certain signed bin files need...
Is it possible to read from multiple ADC channels on Nucleo L011K4 (or on L081KZ)
Hi! I'm pretty new to STM microcontrollers and I found myself in a strange situation:I want to create a prototype for a project on Nucleo-L011K4 (and later use L081KZ for the PCB version) and I need to run ADC on multiple sensors paralel. But all tut...
