For example, if two pins are set, via the Alternative Function registers, to be the rx and tx for a UART, but that UART is disabled, what state are the pins left in if the various GPIO registers are not changed?Does the rx pin remain an input, and th...
Hello, I am new to the whole stm32 environment. I've always used arduino in the past and I wanted to try something new for this project.I am having a really hard time setting up an i2c connection between a nucleo board (MASTER) and an arduino(SLAVE)....
Hi team, I am using STM32L052K8U6 package in my design. I need to configure the internal reference voltage instead of external reference voltage for ADC. Can i get any example program for same.
Hi,I am trying to get the NMEA data over UART and print it over another uart .But when i try read in loop after writing data to PC ,I'm not receiving any data. what could be the issue?any ideas ??
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...
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...
