Posted on August 08, 2014 at 19:27Hi:I am using a STM3221G-EVAL board from ST. Attached is the IAR project I downloaded from the STM32CubeF2 folder that examples the GPIO.The example uses 2 Pushbuttons, KEY and WAKEUP to turn ON 2 LEDs on the board....
Posted on August 08, 2014 at 15:07After reading through the promotional material, datasheet and reference manual for the STM32F3's SDADC and spending a few days trying to obtain a 16KHz sampling rate, I believe some clarification of the limitations ...
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 08, 2014 at 16:05I designed a servomotor control using PWM. I used Timer 3 and works extremely well. I then tried it on Timer 15, the motor vibrates with the same set of PID and algorithms that worked with Timer 3. I read the manual...
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...
