STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi, Currently, we are working with STM32L476JGY6TR MCU. We are facing HAL_I2C_ErrorCallback - 0x00000004 error randomly while communicating with MCU. We are communicating with the MCU Frequently with particular time intervals. In this scenario, some...
I tried to use ADC in F411 to read two ADC inputs.My hardware is a F411-Nucleo board; my IDE is CubeIDE.The followings are my ADC settings in IDE: I use 2 channels in ADC1 (IN1, IN4)I also use DMA to obtain ADC results...
Hello everybody,I want to use the STM32F042G6U6 MCU with one button on PA6 pin if I press the button it should toggle between STOP mode and run. Is this possible at all?How can I do this? I was able to enter STOP mode or exit from it but I cant toggl...
Hello! I am using the STM32F446RE Nucleo Board and succeeded in sending a signal chain via DMA to the GPIO Bank B, i.e. the BSRR register. The DMA trigger works very fine. However, one of the 8 signals is missing/not generated/skipped... This is whe...
Hi,We have a custom firmware running in an STM32F427, and I'd like to find out what the highest frequency supported on a timer with an external clock source using ETR function.Based on AN4776, I can use a prescaler function (ETR) to read clock freque...
Hi all!I am making a PCB with STM32H723, and have chosen this MCU due to its greats specs and versatility. However I would like to add at least 4Mbit (0.5MB) of RAM, either as SDRAM, SRAM or PSRAM etc. using the FMC (Flexible memory controller). Howe...
Dear Community, even after reading what feels like 100 posts, I still can't manage to set the filter so that exclusively 2 IDs are let through.I use the extendet ID, 1 Byte IDs and have managed to let exactly one ID through with the MASK_MODE, as you...
I m using FreeRTOS functions and discovered that the osDelay could only works on mini second, anyway to perform at micro second and nano second delay? If i create a micro second delay using timer TIM1 will that satisfy real-time prerequisite? Anyone ...
Hi guys -I am designing a motor control board around an STM32G474. Main power (for driving the voltage regulators, motor drivers, and ultimately the STM itself) will be provided by a large LiPo. Backup power (VBAT, to keep the RTC on the STM, and i...
Hello,I need to detect input when it goes over REF/2 (1.65V). I do supply VREF+ pin with 3.3000V.My signal has offset of 1.2V, and it will go over 2V when I apply signal to it.Everything is working, but it has unexpected behavior. I can only use nega...
