Posted on September 26, 2014 at 15:29Hi, I configurated the PB4 pin in iterrupt mode, every time you shoot the interrup the led is toggled. If the source code is compiled in start address 0x800 0000 it's ok, the interrupt it's ok and the led is tog...
Posted on October 01, 2014 at 17:23 HI, I want to read the value of a potentiometer; I have this ADC: #include ''stm32f4xx_adc.h'' #include ''stm32f4xx_gpio.h'' #include ''stm32f4xx_rcc.h'' #include ''pwm2.h'' void adc_configur...
Posted on October 02, 2014 at 19:55Hi everyone, So i wanted to get into ST ARMs microcontrolers. I only used TI Tivas before but i wanted to try out the ST ones.Well i would like to know if anyone could provide some links to tutorials and such. My m...
Posted on October 02, 2014 at 15:36Hi,I�m running a single ADC in continuous mode with fADC = 21MHz and expect it to provide 1.4MSPS. I seem to be getting only 0.55MSPS. Can anybody explain why this might be?According to the STM32F407xx Datasheet (D...
Posted on October 02, 2014 at 17:05Hello,I try to test my application with a new setup with external SRAM on the STM3240G kit, for heap and stack.I use FatFS on SDIO which needs DMA. When I read a file there is a problem.I know it is not possible to...
Posted on October 02, 2014 at 21:51Hello, I am having hard time to figure this out. in the data sheet it is mentioned that the STM32F407 works at a maximum clock of 168 Mhz, but using any module timer, PWM or any other the clock is divided by ...
Posted on October 01, 2014 at 09:43Hi, I'm working on stm32f4 mcu and I'm using CubeMX to generate the code useful for my applications, so I'm wondering if it is possible to generate CubeMX code using my personal API; in other words, I'd like to lin...
Posted on September 30, 2014 at 23:20 I am trying to get the ADC working on a STM32F302 processor and I am noticing while single stepping the code is when I call�? HAL_StatusTypeDef HAL_ADC_Start(ADC_HandleTypeDef* hadc)�? and exercise the code t...
Posted on January 05, 2012 at 18:47I have created an Excel spreadsheet to help in the Discovery-F4 pin assignment process, and as a useful reference for the pin functions. The STM32-Discovery-F4 pinout spreadsheet lists the Discovery modules pin i...
Posted on October 01, 2014 at 20:31Using a STM32F427, I've got TIM5 generating an 8MHz PWM output. I've also got a GPIO output that is hooked to an active LOW enable on a device that needs to be turned on every once in awhile. What I'd like to do is...
