I am using stm32 L4 family microcontroller. I enabled MSC mode to copy files from SD card mounted to device to PC. But I want to know how can I monitor the status from my code running in MCU? My program should check whether file copy in progress, com...
Hello. I'm trying to receive data from W25Q128 via SPI. It works good, but too slow, if I don't use DMA. If I'm using DMA, it works faster, but only once, second query doesn't return data.I'm reading flash in main loop once in second this way, when d...
Hello,for an upcoming project I am searching for a low-power microcontroller with a rich peripheral set and the possibility to sample low frequency signals in the range from -0.4V to 3.6V .As far as I have looked it up I will have no chance realising...
I have tried using the examples to generate the code , but it seems it does not create an MDK-ARM project. I only see the Matlab generated files but no MDK-ARM project which I can flash directly to the device.I was previously using Matlab 2015b, Wind...
Hi,i want to implement double buffer mode in USART-DMA(STM32F7) .is there any example programs available with double buffer mode??Thanks in advance
I'm in the early stages of a project involving SPI. I need to send data to an stm32f303, from an rPi.I also need to detect, from the rPi, a GPIO based interrupt to then go read from the stm32.rPi is master, stm32 is slave.Can anyone recommend a helpf...
I've been working on making my SD SDIO card access non blocking. My implementation is a derivative from the standard ST SDIO SD driver (stm324xg_eval_sdio_sd).I'm using Protothreads (basically a state machine) to make the SD SDIO calls non-blocking a...
Dear all,I am trying to communicate to a flash memory using the STM32H750 micro and its QUADSPI interface. For this I use the STM32H750B-DK Discovery board which provides a dual external flashmemory (MT25QL512). In my first example I am just trying t...
Hello everyone,I've just develop my board with this MCU and a QSPI Flash from Micron (N25Q128).The connections suggested by the Cube are:CS -> PB6CLK -> PB2D0 -> PF8D1 -> PF9D2 -> PE2D3 -> PA1Checked them and they are phisically good.I'm using IAR so...
