Resolved! I/O logic support at 1.2V for QSPI
Hi,we are planning to use STM32H742xI/G controller in our design, we have reviewed the datasheet and need a clarification on the IO logic for QSPI.Does this controller supports 1.2v IO logic for the QSPI.

Are VREFINT and VREFBUF output the same on STM32G4?
Moved from this post . Hi @mƎALLEm ,Is VREFINT and VREFBUF output same?In documents I have seen VREFBUF can be set as 2.048, 2.5, 2.9, is that same VREFINT?
STM32 ADC vrefbuf and vrefint
Hi,I’m using the STM32G491RET6 MCU and currently working on the ADC.I have three analog inputs:Two connected to ADC1One connected to ADC2At the moment, the ADCs are configured to use an external VREF+.I would like to switch to the internal reference ...
STM32U5 ADC + TIM TRGO + DMA: repeated samples when reading ADC at 100us interval
I am using STM32U575 (MCLK = 160 MHz) with ADC1 in scan mode (4 channels).ADC conversions are triggered by TIM3 TRGO and results are transferred by DMA in circular mode.Continuous conversion is disabled.TIM3 is configured to trigger ADC every 100 us ...
48 bit SPI implementation
Hi there,I'm attempting to use an STM32 U5 device to interface with another device over SPI, and am trying to do it using 48 bit SPI frames supported by this device.An illustration of what I'm trying to accomplish is below, the key is to be able to t...
NUCLEO-F767ZI USB Host repeatedly connects then disconnects
Hello all, I've come here for a issue I failed to debug. My setup is as follows: I have a NUCLEO-F767Z development board and im debugging/programming it through the onboard STLINKV2 with SWO enabled. I am simply just trying to get a USB device to enu...
Resolved! What can keep the ADC from finishing a conversion? (STM32G474)
I am trying to complete one – just one – ADC conversion without using DMA. This is sort of a one-off sampling after power-on, and subsquently the regular sequence conversion with DMA is to take over. But I don't get that far.I'm trying to sample ADC1...
Use pin as both SPI MISO and GPIO/EXTI input
I use external ADC (slave) with pins with dual function. And when SPI don't work , on MISO pin can check and "end of conversion". This is when SPI pin NSS is high.So: can I activate pin first like SPI "alternative pin" (pin is input - MISO) and like...
ADC not working with PCLK / 4 ?
Hi, Im using STM32g0b1 ADC in continous mode.I am continously converting channels 0,1 and 2. Everything works perfect when clocking the ADC with PCLK/2.SYSCLOCK is 64MHzPCLK is 64MHz so ADCCLOCK is 32MHz.I get End-of-Conversion Interrupts correctly a...
Resolved! STM32U5G9J RTC 24 hours format doesn't work.
I work on the STM32U5G9J-DK2 and what I noticed, the RTC doesn't accepted properly hour value which is greater than 12. Than calendar doesn't work, don't actuallize and the hours going UP for example from 23 to 24 and from 24 to 25 and so on... It's ...
