We're bringing up yet another custom board with the STM32H735 as the core processor. Built the first one, handed it to the software guy, and a few minutes later he says it's broken. Won't program, won't go to DFU mode, nothing. "You must have zapped ...
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...
I have configured the comparator 2 PB6 on the STM32G071RB Nucleo board. It is configured for rising edge interrupt. As soon as HAL_COMP_Start is called on the COMP you can see the EXTI rising edge interrupt flag immediately go high. (well not immedi...
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...
I'm using a stm32G0 with a UCPD and i'm trying to figure out if the Dead battery pin have any other benefit then just saving the need for 2 resisters on the board. From my understanding i could create the same functionality of the dead battery pin by...
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.
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...
