Hello, I am using the STM3210E-EVLA board. I want to create files on an SD card. While consulting the documentation for the STM3210E, I noticed that the size of the SD card is 128 Mbytes, whereas I am using an 8-GbytesSD card. I have written a simple...

Hello all,I am trying to interface 24C16RP EEPROM with my MCU soldered on breakout board and it seems like the EEPROM is behaving very weird when i am trying to write and read. first of all it starts to write from position 1 not from zero of an arra...
For the onboard OV5640 camera module that comes with the STM32U575I-EV, I would like to know how to get several of the largest resolutions for my JPEGs. I noticed the 2592x1944 that the OV5640 datasheet lists, but I'm also interested in whether other...
The example project I'm basing most of my code off of is from the STM32CubeU5 MCU package v1.4.0 (Projects\STM32U575I-EV\Applications\FileX\Fx_uSD_File_Edit). I'm looking to eventually apply this code to my primary project that saves JPEGs from a ca...
I previously made another post regarding minimal adjustments to the DCMI example from the v1.4.0 MCU package. I've made several changes since and now, instead of determining the expected performance, would like to maximize the performance, namely the...
Hi everyone :)I need your help. I am currently writing my masther thesis and I need robust and not noisy ADC read. I am using Nucleo board in my project so I hope hardware should have no effect in my case. The problem is ADC quality. I've tested thre...
About a month ago (April 2021) I purchased STM32F469I-Disco from mouser.de here in Germany, my first discovery board with display. Things went fishy from day 1, but only after more than 2 weeks of black screen I realized: my disco has a different scr...
hi I would like to know what does the f means in both 1000.0f and 2000.f ? anyone can kindly advise? ScalingFactor = 1000.0f/32768.0f; ScalingFactor = 2000.0f/32768.0f;
Hi there,I wrote some data to the Nand Flash which is extended by FMC.The address of Nand Flash is 0x70000000 in STM32F429BIT6.I can read the Nand Flash data by HAL_NAND_Read_Page_8b() correctly.But when I access the data by memory map mode, the data...
