clarification on STM32L4Q5RGT6 OCTOSPI voltage range
Hi we need a clarification on this controller STM32L4Q5RGT6 here it is mentioned as voltage range V1 and voltage range V2. can you clarify what voltage exactly refers to Voltage v1 and v2 and in which IO volt does this OCTOSPI works.
Resolved! STM32U073: measure VBAT pin voltage when VDDA(3.0V) and VREF+(2.5V) are separated?
Hi everyone.I'm using the STM32U073Mx / LQFP-80 pin.While designing a schematic, I ran out of ports, so I'm curious to see if I can use the VDD (battery voltage) to VBAT pin trick to measure the battery voltage. I'm looking at the datasheet and refer...
STM32h7s7: CubeIde Indexing lost after adding external loader in IOC file
Hello there,I'm trying to create a project for stm32h7s7 with external loader. But when i added the external loader in IOC file the all indexes were lost in editor mode. But I checked for building, i can't see any problem. I tried index -> rebuild bu...
Resolved! STM32N657I0HxQ - Custom Board - FSBL Load & Run issue
Hello, I have designed a custom PCB using STM32N657I0HxQ and W25Q32JWZPIQ NOR flash. I am following the STM32N6 FSBL Load & Run tutorial https://community.st.com/t5/stm32-mcus/how-to-create-an-stm32n6-fsbl-load-and-run/ta-p/768206 , but have troub...
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.
Hint on STM32G030x6/x8 Errata: Boot select after debug interface connection (empty device)
The Errata sheet for STM32G030x6/x8, ES0486 - Rev 6, states in chapter 2.2.9:After connecting the debug interface and until the device power-down, the boot source upon reset or wakeup from a low-power mode is determined by the PA14-BOOT0 pin level be...
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 ...
Facing Ethernet Ping Issue using FreeRTOS for STM32F767.
I am using STM32F767 with LWIP and LAN8742 PHY.Ethernet initializes but I am facing Ping does not work reliably. This is the Schematic.
