I'm trying to get a USB virtial COM Port working on the STM32 Nucleo-H745ZI-Q. I've generated some minimal code to initialize the device on PA11 and PA12 and have tried connecting a four pin USB-C breakout board to wire GND, DP, DM, and U5V, as well ...
Split from Black Pill: Debugging STM32F103RCT6 in Keil Fails to Enter main()Hi @mƎALLEm , just about your "not genuine" statement:>- No "ARM " markingSame here on a F103 by STM , should be genuine, because its st-link on a F3-discovery board !>- The...
The datasheets for the new STM32U3 MCUs (375/385) list wake-up from stop3 on SMPS in uA (current), whereas for LDO the docs list the same specs in charge (nAs).Checking the U5 datasheet and the numbers are correctly listed in nAs units. However, the ...
Hello,I have an application which I would like to build on to of cubeMX generated HAL driver, but I came across strange issue that I am unable to keep RTC value on reset. Drivers part is as generated with cube using freeRTOS. system reset is triggere...
Hi everyone,I'm developing a bare-metal application with an STM32H725RG MCU using STM32CubeIDE (including HAL and code generation).I want to use the IWDG1 for reliability purposes, but for some reason, it seems to not work for me at all - upon startu...
Hi,I am working on STM32 MCU, in my application once I start IWDG, based on certain event I want to freeze IWDG.Since my application is running, I don't want to reboot MCU.Once event processed, I want to continue IWDG without resetting MCU.Can anyone...
I am trying to use the bootloader of the STM32G474QET6 with USART to program my microcontroller. I have multiple questions regarding this but the first one is more about hardware. I have found in AN2606 that for the bootloader I can only use one of t...
Hi Everyone,I interfaced Nucleo F767ZI with W25Q256JV using SPI and everything was working fine. But due to time and speed requirements, now I have to shift it to QSPI. I have used example code of STM Document named "QSPI_F769_discovery_flashloader" ...
Hi all,I'd just like to report an error on the reference manual for RMSTM32F411 (RM 0383 Rev 3).The error is located on page 471, on section RTC Register Map.The table showcase all registers for the RCC and miss the entry for RTC_SHIFTR (located at a...
Hello, ST experts The temperature sensor in STM32U595 is used for a mesurement. As datasheet said TS_CAL1 can be read at address 0x0BFA0710~0x0BFA0711. But this value is for 3.0V VREF, how is the situation if VREF and VDDA is 3.3V? How can I get the ...
