Posted on February 25, 2014 at 15:30 Hi guys, I need help to configure the stm32f4 clock to disable the pll and just work with the 8MHz external crystal of the discovery board. The goal is to reduce as much as possible the consumpt...
Posted on February 25, 2014 at 16:57Hello We are using the FSMC on the STM32F103 to drive a lc-display. To generate the Backlight PWM we like to use PD12 remapped to Timer4_Ch1. Now I have the problem that every time the fsmc sends data, a signal is...
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 25, 2014 at 10:09Hello, while most for of the STM32F050 series is NRND, STM32F050F6 is still active. However it seems identical with STM32F031F6. Do I miss something? #stm32f0
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_...
