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 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...
Posted on June 01, 2016 at 14:23 Hello, I am working on the STM32L476G board, with my own code (except using: stm32l4xx.h, stm32l476xx.h, system_stm32l4xx.h,startup_stm32l476xx.sand core_cm4.h). Which means that i'm building my own usa...
Posted on June 06, 2016 at 07:04 Hi there, I have a problem when I'm sending data to and from external SPI chip (Spansion S25FL032P). The problem is I'm getting a really weird signals when I'm over 2,5 MHz speed (see the attached images). I'm...
Posted on June 03, 2016 at 23:29 When import an STM32CubeMX generated project under System Workbench for STM32 follow the instruction of http://www.openstmorg/Importing+a+STCubeMX+generated+project. Numerous errors shown: unknown ty...
Posted on June 06, 2016 at 09:28hi,I'm using stm32f103rct6 to communicate with OPT3001 sensors.I use I2C1 for the configurationto read data from 16bits register it's done but I have problem to send 16bits data.I used this function when I tried to re...
