Posted on July 25, 2014 at 21:46Hi, Can someone please throw some ideas on what might be the problem with what I am seeing / doing. Here are the relevant details. 1 - Using an STM32F407 processor (Discovery PCB), clock at 168Mhz 2 - Using ADC to sa...
Posted on July 25, 2014 at 10:33Hi, I'd like to program STM32F373s via their usart1 from an STM32F2, though the latter should be irrelevant, I think. The board has the STM32F2 controlling four STM32F373 processors as peripheral controllers and talks...
Posted on July 25, 2014 at 11:17When use STM32CubeMX, if you disable CRC, it won't initialize the SPI structure, but the STM32F4Cube will assert the “Init.CRCPolynomial�, then it failed.STM32Cube is a good idea, but i want to know if i have some...
Posted on July 24, 2014 at 05:13HI,I have faced one problem with PORTF pin configuration (PF0,PF1).My GPIO configuration:RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOF, ENABLE); InitGpio.GPIO_Pin = (GPIO_Pin_0 | GPIO_Pin_1 ); InitGpio.GPIO_Mode = GPIO_Mo...
Posted on July 25, 2014 at 12:44Hi all, I have to interface external oscillator to stm32f407igt6 which is having 16Mhz internal frequency and i need to boost it to 168Mhz frequency by connecting a 25Mhz external oscillator so can anyone giv...
Posted on April 30, 2014 at 04:45 hi, I have a custom designed board with STM32F07 IC. The FSMC interface is working with certain version of software. recently i tried to use CubeMX to generate low-level code with FSMC HAL. I only added a...
Posted on July 25, 2014 at 02:53What is the use of the GPIOx_MODER Alternate function mode? Is it needed when an appropriate non-zero value is put into GPIOx_AFRL/H? Is the GPIOx_MODER alternate function mode value only needed for those few altern...
Posted on July 22, 2014 at 12:31I have configured the clock for 168 mhz and for tim2 84 mhz , presaclar = 2 and arr = 200 it is showing 4.6 us in stm32f407vgt6...but in stm32f407igt6 it is showing 24 us .....I have checked the system_init actually i...
Posted on July 24, 2014 at 02:26STM32F4xxx Reference Manual, DM00031020 rev 6, has the �FPU� interrupt vector at position 81, address 0x00000184 (or 0x08000184 depending on how one views low ROM). I found no documentation about what this vector is ...
Posted on July 24, 2014 at 22:55Hi,I am trying to develop an application for STM32L series. I need to use DMA in double buffer mode. I found information in the reference manual for a double buffer circular mode which uses a single DMA buffer with ha...
