Posted on January 16, 2013 at 11:39Hi, i'm using the stm3240f board with a stm32f4-series.I try to generate PWM but nothing happen.what i did : /*declaration-----------------------------------------*/TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;TI...
Posted on February 25, 2014 at 12:11Hi ; We produce madical instruments ; our main products depends on stm32f407 and we are happy with it ; Now are designing a new product that needs many DSP filters ( FIR + IIR ) ; the sampling rate would be abou...
Posted on February 25, 2014 at 13:54UPDATE: The TIM_SelectInputTrigger function and the TIM_ITRxExternalClockConfig function both write to the TS bits in the TIMx_SMCR register so the final value is ITR2 overwriting the TI1FP1 value set. Because I ...

Posted on February 22, 2014 at 14:31I used the discovery kit to prototype a control-board. The self developed board using the stm32F4 MPU works well. Thus far i flashed it with the st link debugger that is integrated into the kit, which worked fine....
Posted on February 24, 2014 at 06:27 Hi , I am using STM32F429 discovery. The system tick is suppose to produce an interrupt every 1ms. However, i have gotten 3.12ms instead. Did i make a mistake ? int main(void) { Init_...
Posted on February 23, 2014 at 16:05 Dear all, I'm having problems to understand what's happening. While searching for the cause of the error I started from the scratch - the code is stripped down to the bare minimum. I think any cross interf...
Posted on February 12, 2014 at 15:07 Hello, I'm trying to interface the STM32L152 Discovery with an LCD display (NHD-C0220BiZ-FSW-FBW-3V3M) through I2C. I'm finding a problem when trying to write the first command to the LCD the code gets...
Posted on February 19, 2014 at 14:10 Hi all, I have a question about HSE clock source. I loaded the demo and added some code to check the HSE clock on PA8. ... GPIO_InitTypeDef GPIO_InitStructure; ... int main(void){ ... RCC_HS...
Posted on February 23, 2014 at 09:41Quick question: I've got a 4-pin SPI port on an STM32F3 available (and no other pins; they're all occupied) and I need to talk to an LSM9DS0 sensor. The LSM9DS0 has two separate SPI interfaces, one for the gyro pa...
