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...
Posted on June 06, 2016 at 16:25Guys, Does anyone have information on using STM32F4 Discovery with MP3 helix ? Thanks
Posted on June 06, 2016 at 22:26Can anyone here tell by the location of the 'smoke' holes in this STM32F103C8T6 what caused the failure? There does not appear to be any other failed components on the board. The boards 3.3v regulator is still worki...
