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...
Posted on June 04, 2016 at 01:37 I developed a board using STM32F411 chip with uSD card.The code is generated by cubemx. only add a little bit code in main(). The hardware is OK. I can correctly write a file to sd card. But the weird thing is th...
Posted on May 30, 2016 at 10:31Hi!I'm trying to run a bldc motor with stm32f407 IC. The most common method to do that is six-step mode control. I configured TIM1 in complementary mode. but as you know, timer mode must be changed during each step.For...
