Posted on August 16, 2016 at 09:56Hi all,Is there a way to calculate the size of used RAM at running time. So that I can calculate how much RAM is still available for use. Actually I have to show used RAM in percentage to my product customer.
Posted on August 16, 2016 at 13:29 Hello, I want to read/write files on a usb stick in my application and I already have generated a project with the help of ST32CubeMX for my Nucleo-F746ZG board. The configuration in CubeMX is: ...
Posted on August 13, 2016 at 00:31Hi, I'm new to programming the STM32 micro. That's way the Cubemx tool is very helpful for initializing the STM32. Also ther are a lot of examples in the repository, but i don't understand why the examples are not w...
Posted on August 16, 2016 at 04:31I have a project generated by ST32CubeMX that uses the SDIO hardware to talk to SD cards that is generating a hard fault when doing any sort of file access. I'm not sure exactly what is going on since the project i...
Posted on December 22, 2013 at 14:55Hello.I'm using mp45dt02 mic on the discovery board and just forwarding data to cs43l22. For sampling freq 16k is working fine, but if I want higher Fs, it doesn't work anymore. I'm only hearing beeping/scratching...
Posted on July 09, 2013 at 08:50Good morning everyone,I'm currently working on a project with a ST32 and my goal is to be able to give him simple instruction in Modbus TCP/IP thanks to an Ethernet cable. Presently I've been able to code functions in...
Posted on August 11, 2016 at 17:37Hi, I'd like to designe a PCB with a STM32F7xx. You use to have in the Design/Schematic Packs also the xxx.PCBDOC. E.g. STM3210C-EVAL (MB784C, MB785A) They save lot of work and time. But I miss the PCB Document for...
Posted on June 20, 2016 at 23:21Hello Forum, I've been reading on the forums about custom bootloaders stored in flash and I was wondering if there was another possibility (possibly because I want to avoid messing with stack pointers, reset vectors e...
Posted on August 12, 2016 at 07:27STM32 external SDRAM(32bit width,FSMC interface) 16bit and 32bit writing OK,but 8bit writing is not OK, shown below,source file is also attached. Test Results uint8_t write_buf1[100];write_buf1[0] = 0x01; //0xC000...
Posted on August 14, 2016 at 19:19Hi,I would like to utilize either a 128Mb or 256Mb, and someday, maybe even a 4Gb external SDRAM chip. If they can just be swapped out on the board all the better.The F7-DISCO makes a point that due to design consi...
