Posted on October 19, 2012 at 16:47Hello, I am having problems with the syStick timer. The handler for sysTick stops being called after one or two interrupts from TIM3 (set < 1Hz). The TIM3 interrupt has no problem (LED keeps toggling). I started ...
Posted on October 18, 2012 at 17:56Hi,I'm having a bit of trouble configuring the SPI2 clock frequency on an STM32F407VG, or perhaps I am confused as to how it works.Using a 25Mhz external oscillator, boosting up to system clock frequency of 168MHz....
Posted on October 19, 2012 at 10:18Hello All, I am using STM32Fs series and I am writing a code for SPI2 . I have to read and write from the slave device. I have to read the data when RX buffer is full and write data continuoulsy to another device....
Posted on October 18, 2012 at 11:01 Hi, Im using a STM32f405RG and i am trying to get a simple USART example to work. I load the following code to the mcu: #include ''stm32f4xx.h'' #include ''stm32f4xx_gpio.h'' #include ''st...
Posted on October 16, 2012 at 18:50hello forum, the processor is STM32F103 I have an H bridge for DC motor I want complementary outputs of CH1 and CH1N I setup the timer 1 as following TIM_TimeBaseStructure.TIM_Prescaler = 0; TIM_Tim...

Posted on October 17, 2012 at 11:48Hi everyone!I'm new to the world of microcontrollers, these days I'm doing my first espeienze with STM324 discovery, I'm reading the various manuals and trying out the various examples, but I can not understand how...
Posted on October 18, 2012 at 08:59Hi everybody. I used SysTick timer as a counter of time in my application throug using of interruption. I found ''SysTick_Config'' function in core_cm0.h file. This function load time to reload register and switch ...
Posted on October 17, 2012 at 11:38Due to an error in manufacturing we have a lot of modules with a 32khz resonator with 12.5 pF for low speed external clock and two 27pF aditional capacitor to ground. Prozessor is the STM32F103RCT6. The real time ...
Posted on October 17, 2012 at 01:49Hi All,I’m using an STM32F103x. I need to count the number of external pulses from a hardware detector, and take a snap shot of the pulse count at a precise frequency of 100,000 kHz.My current setup uses TIM5 CH...
