Posted on August 06, 2014 at 11:49Hello there!I've interfaced 128 MB(16 bit data bus) sdram through fmc interface in my stm32f429 device. Initialization and everything seems ok. Reading/writing to sdram is ok for small chunks. But writing 12 MB or l...
Posted on August 05, 2014 at 15:54I have a 32F429I discovery board and I have some parameters, e.g. touch screen calibration information, that I would like to store in a non volatile memory. As far as I understand it I have the options of:1 - storin...
Posted on August 07, 2014 at 12:50 hello, I want to send some data using spi but I see anything on my scope when I use this code. does anyone know where is the problem? Thanks #include < stddef.h > #include ''stm32f0xx_rcc.h'' #incl...
Posted on August 09, 2013 at 23:41Hi,I am working on a simple custom HW design based on the STM32L SoC.The STM32L is connected to several LEDs as well as a microphone along with other external devices like batteries, switches etc .. The firmware is ...
Posted on July 01, 2014 at 09:10Hi,i use the timer 10 to toggle a GPIO with a board STM32F429-DISCO.int init_timer ( void ){TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;NVIC_InitTypeDef NVIC_InitStructure;RCC_APB2PeriphClockCmd (RCC...
Posted on August 31, 2012 at 20:51 Hi, at the moment I'm using the following code to recieve a byte: char ReceivedData = NULL; void main() { . . . while (1){ /* Wait until a byte is received */ while (USART_GetFlagStatus(USART...
Posted on August 07, 2014 at 23:26I am setting up stepper motor control on an STM32F4xxx using Full Step Drive as in http://en.wikipedia.org/wiki/File:Drive.pngBoth timers are setup as up counters with PWM output. Timer 2 controls phases A & C. Time...
Posted on May 14, 2014 at 09:37Hi!I would like to use the external RAM IS42S16400 present into the demo board STM32F429DISCO to store program variables. To do that i modify the linker script MEMORY{ FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048K R...
Posted on August 07, 2014 at 10:24Hello ST,I have found a discrepancy between the documentation of the STM32F2x MCU and the STM32Cube as well as the StdPeriph implemenation.On page 656 of the RM (RM0033_CD00225773, DocID15403 Rev 6) it is said that ...
Posted on August 07, 2014 at 19:59I use STM32f107 for audio broadcasting in ethernet network.I use trigged ADC (timer) to generate 8KHz PCM and buffer ADC data with DMA and make Alaw(G711,Fast conversation,table based) and send data with UDP. I use ...
