Posted on March 19, 2015 at 08:24I'm new to STM32 so downloaded Keil V5 and stm32cubef4. Tried compiling the first example using the STM32F4-DISCOVERY. I got many errors so changed the include location in the project properties then compiled but got...
Posted on March 19, 2015 at 12:07can any one help me with this problem? I try to save value in the user configured section of flash memory and restore it after power reset through hal_stm32f4xx library. I started debugging by reading the value from...
Posted on March 13, 2015 at 10:47Hi I use a STM32L100C-DISCO kit. I want to use I2S interface. I configure this interface with STM32CubeMX: I enable I2S2 as Half Duplex Master, I choose HSI and internal clocks to have an audio clock of 48kHz. Every...
Posted on March 18, 2015 at 16:34Hey,I am currently working on a project with an STM32F4 MCU. My board works fine until I try to put some output high and then a few seconds later low, this is done with starting a timer. After a couple of times for s...
Posted on September 01, 2014 at 13:25I have a STM32F405RG with external 16MHz crystal which is also used, divided by 16 as the RTC clock source. The project has been built using VisualGDB. The problem is that the RTC appears to stop after it is rea...
Posted on March 18, 2015 at 18:06 Is there a maximum ratio of FCLK and external SPI clock? I use STM32F030 with SPI module as slave. What is the maximum external SPI master clock? I'd use low speed clock at my STM32 (HSI 8MHz, or maybe HSI+PLL de...
Posted on January 08, 2015 at 10:26Hi Guys,I am using the STM32F207VG development board.I'm having problem in compiling the example codes given by STM. Since there is no dedicated IDE for STM32 devices what is the recommended FREE IDE from STM? I ma...
Posted on March 11, 2015 at 05:00Dear all, I am doing a project that control a quadcopter using STM32F103. At this moment, I have done about the control of DC motor. However, my quad. is not stable when it takes off. I am going to use IMU 6DOF ( ...
Posted on March 18, 2015 at 09:04HiI have a bit of a problem when using malloc so I was wondering what others think about this. I use malloc in my application, mainly because the application is entirely asynchronous so either I have to use malloc or...
Posted on March 16, 2015 at 16:53I have programmed a set of GPIOs to be SPI. When I program the SPI clock to be anything faster than 4MHz, the rise times of the clock, MISO and MOSI signals is unacceptable (the clock signal is very rounded and not c...
