Posted on June 07, 2016 at 19:06Hi,I have an STM32F746 connected to an other processor through UART (TX-RX). The goal is to exchange data with this other processor with a library provided by the supplier. The only things I have to do is to re write ...
Posted on June 05, 2016 at 02:32Hello, I would like to use the uC to measure three-phase power. I have six analog channels (3 for the voltages, and 3 for the currents). I would like to use the ADC1 and ADC2 to simultaneously sample the voltage and t...
Posted on June 08, 2016 at 09:05Hello,Here I've got a board hosting a sensor communicatingvia I2C.The Board is based on a STM32F410RBT***I use the HALdrivers! below you can find the manual:http://www.st.com/content/ccc/resource/technical/document/us...
Posted on June 07, 2016 at 16:54Dear All, I am using CubeMx F4 V1.12.0 I want to use I2C with DMA on the STM32F429 but it is not working. In the stm32f4xx_hal_i2c.c it is noted (+++) Configure the priority and enable the NVIC for the t...
Posted on June 07, 2016 at 11:16I cannot see any link to the actual (original, SPL-based) firmware package for the F3 discovery board - or I just can't see it. Here the page: http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedd...
Posted on June 07, 2016 at 20:46Hi to all, I got a problem with GPIO interrupt. I have two buttons connected to pin 13 and 14 of port A. I configured pins in input and enabled interrupt, then I wrote the interrupt routine. When I pushed a button I g...

Posted on June 07, 2016 at 14:55Hi all, I try to understand break input.I read break input title in datasheet.Refer to ''The break functionprotects power switches driven by PWM signals generated with the advanced timers.'' in the datasheet. But I ...
Posted on June 07, 2016 at 08:02Hi,I am working on STM32L4xx MCU. I have connected MicroSD card of 8GB size over SDMMC interface. And I am using DMA for write to the SD card.Now, DMA is used to keep the MCU free during that time of data transfer. Bu...
Posted on June 07, 2016 at 11:40Hello,my problem should be simple to solve, but due to it's rather undocumented nature I resort on posting it to this forum. When plugging in the STM32F429 board into a pc, it gets detected as flashdrive with around 2...
