Hello,I'm using a microSD connected with SPI to a STM32F4 microcontroller. I have used MLC micro SD card with fatfs for years without any issues. Recently, I have switched to SLC NAND micro SD, Industrial grade, with Wear Leveling (for application sp...
I got two things i dont understand or needs more information. In the manual it says"The Flash memory is programmed 72 bits at a time (64 bits + 8 bits ECC)."I somewhat know about ECC, but i dont know about the "8 bits". Can i just ignore this? Progra...
Hi All,I am trying to implement a code on STM32H723 Nucleo-144 where the ADC uses DMA configured in double buffer mode. I cant find any examples on how to do it. I have tried to analyze the ADC to DMA in circular mode code, but I struggle to convert ...
Hi community,I am trying to port a project from old library maple leaf or older built for Arduino to to STM32cubeIDEthis function I couldn't find any ref to it, my guess it that is sets the period to 5ms Timer3.setPeriod(1000 / 200); browsing some th...
Hi I am using the USB CDC on a STM32L433 with the command MX_USB_DEVICE_Init(); to communicate through the USB. In my app, I go into standby mode (by using the HAL_PWR_EnterSTANDBYMode()) command. How do I disable the USB before entering standby? I ...
Hello,I've enabled a USB virtual com port on an STM32F373 successfully. The CDC_Receive_FS function in usbd_cdc_if.c gets called when data is received. I never expect to never receive a 'packet' greater than 64 bytes and have created my USB buffer[...
STM32F051C8T6产品，想用来和多摩川的编码器产品通讯，发送数据0x02，多摩川编码器发送6个字节返回。但用6个字节的中断得不到数据，用6个字节读取也无法得到数据。中断只能收到一个字节，02。有指导问题出在哪里了？
using stm32ide and a stm32f407 I would like to change the boot address to 0x8000000 to leave the first 4 sectors free from 0x4000 to position the boot at 0x8010000 I made a series of settings (not sufficient). in flash.ld file change1) FLASH (rx) : ...
Hello, by connecting an mcp2515 to Stm32, I enabled it to communicate properly with other cards via the Can network. However, when a message arrives, I couldn't understand how to receive it with the INT pin and I couldn't do it. I tried connecting th...
Hi,Is there any sample for H755 with lwip eth and sdmmc1 fatfs?.How configure the MPU region?. Thanks,
