Hi,I am using a STM32H743BIT6., I am trying to access two SDRAM part-number(IS42S16320D-7TL)problem:both the DRAMS are wring the same data at the same time, so instead of having access to a 32 bit i am getting access to 16bithelp will be apricatedTh...
i get `FR_NOT_READY`, `HAL_SD_ERROR_REQUEST_NOT_APPLICABLE` errors ./* If requested card supports wide bus operation */if((scr[1U] & SDMMC_WIDE_BUS_SUPPORT) != SDMMC_ALLZERO){//...return HAL_SD_return HAL_SD_ERROR_REQUEST_NOT_APPLICABLE; }ERROR_NONE...
Dear communityI develop a 'robot" with odometrie.Each geared DC motor have a rotary magnetic encoder for speed regulation.My question is about avoid count overload.I use a timer for read encoder count. Each interrupt, i print the value.My aim is avoi...
Hi,I am implementing micro-sd card with STM32H573RI using SDMMC1 interface. I am using HSE clock with input frequency 25MHz and the system clock is running at 250 MHz. SDMMC1 clock mux is sourced by PLL1Q(25MHz).All the SD card initial commands in th...
Hi amazing community. I would like to write some data in the flash memory of the following mcu STM32F103I know there are some dedicated pages for such purpose.How can I guarantee or understand that the future code that i will develop and it will be s...
I have an jetson xavier driving STM32F407G-DISC1 on SPI1 default pins : PA4/5/6/7 .The SPI_FLAG_RXNE flag behaviour is very strange, resulting in wrong values being received.Config used:/* SPI1 parameter configuration*/hspi1.Instance = SPI1;h...
Hi Support I'm running a LVGL demo,set the framebuffer address at extern SDRAM address 0xC0000000 "pLayerCfg.FBStartAdress = ((uint32_t)0xC0000000);" lvgl need a work mem for dynamically allocated data when assign the work mem on IR...
I2C function always stucks at waiting for BTF flag if connectting STM32 with J-LINK debugger to start running program, however, the I2C can send command to slave device well when powered on without debuger control. I just call HAL_I2C_Master_Transmit...
Hello,I'm trying to connect SDRAM to STM32 for the first time and I'm having trouble understanding the specs.In the datasheet, it seems the FMC peripheral can not support 32bit memory. Is it right? and could you recommend 64Mbit SDRAM for STM32H735IG...
Everything was going well until my compiled code exceeded 64kB. Now, the programmer says that the code exceeds available space. But the code is only 67kB and the available space is 128kB.Is there an option that I need to set to allow all flash to b...
