All STM32 datasheets seem to have the Figure "Recommended NRST pin protection" copied and pasted. This figure suggests that an external reset circuit consisting of a BUTTON AND CAPACITOR is recommended to "protect the device against parasitic resets"...
When ever i am trying to copy data in SDRAM garbage value is getting transferred. Please suggest what can i do I have attached necessary files with this post.Kindly suggest.
Hi.I am learning how to turn on LED2 of a NUCLEO-G474RE board by using registers (without HAL).I have created a small project which contains: // This first block works and updates the registers // Start GPIOA Clock (*(uint32_t*)0x4002104C) &= ~(1 ...
I'm looking for the low power function of the STM32F103TB. I have some questions about this function:1. I read the code of the AN2629, there has no interrupt routine code. So when we use the RTC alarm and the PA0 (wake-up pin) to wake up the MCU, whe...
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...
