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...
Hi Team, we are using STM32 for our project there is a need of repeated reading and saving of values, for this purpose currently we are using RTC Backup registers.RTC_BKP_DR0 0x00000000URTC_BKP_DR1 0x00000001URTC_BKP_DR2 0x00000002URTC_BKP_DR3 0x0000...
Dear Community member,We have developed a PCB for Air pollution measurement using STM32G473VET6 MCU. We were able to flash the program successfully, but we didn't receive any output from GPIO, UART, USB, etc. None of the peripherals are working excep...
