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.
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...
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...
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...
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.
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?
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 ...
I am using STM32F767 with LWIP and LAN8742 PHY.Ethernet initializes but I am facing Ping does not work reliably. This is the Schematic.
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 ...
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...
