Posted on December 12, 2013 at 06:16 I've been coding on the STM32F4 for the past couple years and love the MCU. However, I'm having trouble figuring out how to bring in two external signals and use one as the gate for the other. I'm plan...
Posted on December 13, 2013 at 00:55My application use EXTI1 interrupt, SPI1 interrupt and USART1(RXNE) interrupt. USART1 interrupt has highest priority. USART1_IRQHandler is very short, only storing incomming bytes to the circular buffer. When I di...
Posted on December 12, 2013 at 11:22Hi This is Not a software problem. This is an electrical problem! We are seeing a number of unexpected Flash sector erasures/wipes. Typically, we are powering up/down the system connecting/disconnecting USB or RS...
Posted on December 06, 2013 at 08:31 Dear Sir/Madam, I am a novice ARM programmer, trying to get the hang of things. It's a bit more complex than programming an 8-bit AVR controller... Anyway I was wondering, why I cannot read th...
Posted on November 29, 2013 at 16:07Hello, I've an STM32F051 where i2c modules can be connected (SFP video modules) These modules should be hot swappable, however it seems that the I2C communication is not dealing properly with these modules because...
Posted on December 10, 2013 at 03:34Does ARM DS-5 works with STM32F4 out of box?I downloaded one, but seems default project is linux.Thanks #what-it-says-on-the-tin #right-tool-for-the-job
Posted on December 12, 2013 at 15:48 I'm sure there's probably already a post on how to do this, but I can't find it so here goes: I'm trying to set up the external 8 MHz oscillator on the F4 Discovery. I'm using Keil IDE and have set my...
Posted on December 11, 2013 at 22:37Hello ST Community,I am using a STM32F2 uC for my project, and I have configured an USART interface as an UART by not initializing the clock settings. In order to program the device the UART is connected to I send...
