STM32 Virtual Comm port drivers

Posted on October 14, 2012 at 17:22Thank you for existence of such driver. But this driver is unsigned. Virtual com port is very useful for many applications. It is very hard to use unsigned drivers for clients. As ST makes any other drivers and sig...

STM32F4xx - cannot start the pheriperie I2C

Posted on June 06, 2012 at 11:30Hello, Always, when I set on the clock in I2C1 or I2C2, in the status register SR2 is the BUSY bit set. Here the code:int main(void) { I2C1_DBG = (I2C_TypeDef *) I2C1_BASE; // for debugging RCC->APB1ENR |= RCC_APB1ENR...

CPAL I2C STM32F2

Posted on October 12, 2012 at 15:51Hello,I'm using the CPAL library.During the ''CPAL_I2C_Init ()'' when the I2C clock is set on, the BUSY bit in the status register SR2 is always set too. Why the BUSY bit is set ?I'm using the I2C1 on a STM32F217VG...

measure the frequency of the microcontroller from the outside

Posted on October 13, 2012 at 20:32I need to measure from outside the sampling frequency of a STM32F4 discovery, I have thought about using a pin as an output, and bring it in an alternating manner to VDD and GROUND each time the DMA takes a sample ...

help!A problem among BSRR,BSRRL and BSRRH

Posted on October 13, 2012 at 20:22when I build my project,an error ''User\main.c(12): error: &sharp136: struct ''<unnamed>'' has no field ''BSRR'' '' was appeared . k yes,I check the '' STM32F2xx_StdPeriph_Lib_V1.1.0 '' of STM32F2XX , it doesn't...

System Clock, Interrupts and USART data loss

Posted on October 11, 2012 at 20:40Hello, I want to share my story about the use of the microprocessor and the problems arising from it. My system consists of a microprocessor ARM Cortex M3 STM32F103RC6 and various peripherals. I use this system to...

connection failed - u4vision

Posted on October 13, 2012 at 01:59HiI am new to all this so please bear with me.I have just received a STM32 Discovery board (ARMz32F100) and I setup the u4vision from Keil and the DISCOVER example code form STM. But I get failures when I try to d...

va_args, printf, dma memory problem, possible misalignment or linker issue

Posted on October 13, 2012 at 02:59I've been scratching my head for the past few days as I try to understand why and what is going on... So here it goes:Current config: stm32f407VG (same as stm32f4 discovery)I set up a project using the default link...
