How to enable external RAM using SDRAM on STM32F429?

Hi,I'm new to STM microcontrollers.I was wondering if you could help me with running external ram IS42S16400 on STM32F429 using SDRAM interface.I'm attaching my project.Thanks a lot for your help :)

Which guidelines should I follow to write C++ code for STM32? (please do not evangelise me on not using C++ on micro controllers)

STM32f429: problem with using external SDRAM as an additional data memory

Hi,I can read/write an external sdram using fmc in stm32f429. But working with address and read/write functions is not proper for my purpose. I want to introduce external sdram as if internal sram is clearly extended and whenever I define a big varia...

Please help on the clock configration of STM32G431. The clock is mush slower than what I set. it is only 20MHz roughly

I use cubemx to generate clock configAnd I use a flip pin and oscilloscope to check the speed.here is what i didclock settingvoid SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; ...
