Problem: ADC reading a battery voltage jump by twice as much when the battery voltage goes from just under 3.55V to anything above (jump is about 1000 in raw adc reading at 12 bits).Background:We have a custom board with STM32G0B1CB on which we are t...
Does ST have a good default MPU configuration for the STM32H573? When I start a CubeMX project for the H7 series, it asks if I want to use a default configuration. But for the H5 it does not. While I can find forum posts regarding the need to disa...
I want to send USB HID Reports as fast as the MCU or the USB protocol allows. In order to send an USB HID Report on an STM32F103 I'm doing something like: USBD_HID_SendReport(&hUsbDeviceFS, (u8*)&report,sizeof(report)); HAL_Delay(some_delay); or even...
i am using nucleo-144, H743ZI2 board. while i am uploading code in the stm32cubeide i am getting error as "target not found". i have searched in the community and then tried connect the boot0 to high, and power the board, connect to cube programmer a...
I noticed some options in the CUBE IDE for my H745's ADCs labelled "ADC 12-bit optimized resolution" and likewise for 14 bits. I have searched the references and the internet and find no explanation of how "optimized resolution" differs from the regu...
Hello,I am using a STM32H743ZIT6 in a custom PCB, the MCU and reference voltage at 3.3VOur intention is to use the built-in ADC to read some DC signals. One signal is our 24V power rail. In our circuit, nominal 24V is scaled down to 1.643V through a ...
We are working on a design that includes an STM32U545 running at around 1MHz to save battery power for the overall board. We have a requirement to write to an event log when the power is removed (this is the main operating power, not VBAT).The softw...
Hi,I am having Nucleo 476RG board.I configure Alarm A. HAL_RTC_AlarmAEventCallback functions is called upon occurrence of Alarm.Now when I configure AlarmA and then enter standby mode, the board wakes up from the standby mode upon the occurrence of a...
Hello. I have LIS3DH accelerometer and I would like to use it with my ST32F4 board.I have found the BSP drivers :STM32Cube\Repository\STM32Cube_FW_F4_V1.28.0\Drivers\BSP\Components\lis3dshand also available here:https://github.com/STMicroelectronics/...
I cannot enter the bootloader with the BOOT0 pin in the STM32G0C1 while I can with the NUCLEO-G0B1RE.I already checked the option bytes, and tried with nBOOT_SEL = 0 and nBOOT_SEL = 1.In the Nucleo board, it seems this nBOOT_SEL has no effect at all,...
