I need to chain two timers together to get one 48-bit timer that counts microseconds, I'm thinking of using TIM2 as the master and TIM3 as the slave. I have the feeling some of the answers are contained in this table in the Reference Manual but I can...
Hello,I have problem with establishing wifi connection on STM32H7B3I-DK. I am using SPI2. I dont get any response. I am using simple AT command, that should give response 'OK'. This is my int main() and initialisation of SPI2:int main(void){/* USER ...
I’ve been working on a project for a while and initially generated the code only once at the beginning to set up the hardware configuration. Recently, I updated STM32CubeIDE from version 1.14.1 to 1.15.0. After updating, I regenerated the code withou...
Hello,we are using STM32H735G-DK Eval Boards equipped with differently marked STM32H735IGK6U chips.One saying:-------------------STM32H735IGK6UAA126 VQ ZTWN AA 109 D2--------------------and the other one saying:------------------...
Hello STM32 Community,I'm currently working with the RTC peripheral on an STM32F4 device, and I have a question regarding RTC alarm events.I've been able to generate interrupts at specific intervals, such as 250ms or 500ms etc, using the RTC alarm fe...
Hello guys. I'm trying to design a custom pcb that uses an STM32h7a3zit mcu and one of the most confusing parts is clock configuration. I will mainly use the hs usb interface. I've searched a couple of online sources and from what i could find is tha...
Greetings,I'm having a UART Frame Error (identified by relevant bit raised in UART ISR, and relevant error flag routine in UART_IRQHandler) when attempting to running LPUART1 off a 120MHz SysClock on a STM32U575RG present on our boards.I've replicate...
Hello everyone,I hope you're all doing well!I just wanted to take a moment to express my gratitude for all the guidance and assistance I've received from this community. Thanks to your support, my learning journey with ST Microcontrollers, particular...
Hi, I'm wondering if write and erase external flash menory can be done when XIP mode on the same external Octal-Flash?I read RM0477 Rev 4.pdf and it told not recommand to programm the flash in this mode, and indirect mode can do that.Since the MX66UW...
Background:I am capturing an image on OV5640 Camera module. My camera is connected with STM32L4R9I over DCMI protocol. I am further using DMA1 to take image data and store it in PSRAM (with the help of FMC). From PSRAM, image data is being written on...
