Posted on April 04, 2014 at 22:43 There is something basic I am overlooking but haven't been able to figure out what. I've written a bootloader that seemed to work, but maybe it just happened to fall into the new program. I seem ...
Posted on April 02, 2014 at 12:05hello everyonei have adc ad1877, configured as in pictureHow i should configure i2s in stm32f4 ? I have tried this one I2S_InitStructure.I2S_AudioFreq = I2S_AudioFreq_32k; I2S_InitStructure.I2S_Standard = I2S_Stan...
Posted on April 06, 2014 at 05:22 Hey, I'm currently working on a project for my class with the STM32F4 board, and am having difficulty trying to configure the user push button to cause an interrupt. I have used the F3 board a few times, ...
Posted on April 03, 2014 at 20:53All, We are using the STM32F051C8T6.I have some comments and questions below but I mainly wanted to get a thumbs up to make sure I was on the right track with some of my conclusions. Thank you for taking the time t...
Posted on April 04, 2014 at 18:31Hi,I am currently working on a PIR-sensor solution, where 10 PIR-sensors are mounted in an array containing lets say 300 elements, at an even spacing distance.Looks like this:* = PIR♯ = array element without PIR-sens...
Posted on April 04, 2014 at 03:22I would like to use one of the UARTS on the STM32F4 to connect the MCU to a Bluetooth SMART controller. I was wondering if anyone could tell me if there is any access on the board to one of the UARTs so that i can so...
Posted on April 04, 2014 at 17:40After days spent in tries to connect adc via i2s - mcu stopped working. I can write and read flash via st-link, mcu is properly detected but it does nothing. Tried mass erase - did not helped.It seems that works only...
Posted on April 04, 2014 at 13:21I cannot get into DMA mode, the code I wrote did not get into DMA interrupt. The code I wrote is as follows. Any advice?( my processor is STM32F103ZG) uint8_t RxBuffer1[100]; /*UART - Pin Config*/ GPIO_InitTypeDe...
Posted on April 04, 2014 at 17:26Hi, I am trying to get interrupt nesting to work on an STM32F207, but so far without success. I am using no subpriorities (SCB_AIRCR.PRIGROUP = 3) I am inside the hander of TIM6_DAC, and an UART5 interrupt is enabled...
