Posted on February 13, 2014 at 14:11Hi all,I'm using stm32f100c8 with an external oscillator 8MHz to produce a system clock of 24MHz. All the peripherals are on the default division lines.Now the ADC1 which is with the TIM1 on PCLK2 is supposed to r...
Posted on February 10, 2014 at 10:39HiI'm using STM32F373x SPI in slave mode. I get errors in about 0.1% bits transmitted, occurs in 50% of units from first production series of custom board. SPI lines have RC filter installed to improve EMC immunit...
Posted on November 07, 2013 at 12:13Hi, I if will be great if some one clarify me the following, * What is the default interrupt priorities? When I read using either priority4 = NVIC_GetPriority(UART4_IRQn); orpriority4 = NVIC->IP[EXTI4_IRQn];...
Posted on February 13, 2014 at 09:34Good day,Like topic said, the alarm handler does not to work, but if I do like this:while (!RTC_GetITStatus(RTC_IT_ALRA));printf(''\nALARM''); //it worksHere is my code: int main(void){ NVIC_InitTypeDef NVIC_Ini...
Posted on March 15, 2013 at 08:39Hi! The Discovery board based on f407 served me as a starting point in preparing a course on the use of microprocessors for local students, which do not have much experience with hardware, but are familiar with the p...
Posted on June 10, 2013 at 23:31I noticed something strange with the CAN_TransmitStatus function in the stm32f10x_can.c (V3.1.2) peripheral driver code. Most of the time it works fine but occasionally it returns the wrong status. The root cause is i...
Posted on February 05, 2014 at 13:42Hi,Kit using : STM32Discovery Board(STM32F100 controller)I have implemented the input capture mechanism for Timer15 channel 1. In which I set triggering for both falling and rising edge.Now I am trying to port the...
Posted on February 13, 2014 at 05:38I have a bit of code to output some debug using SWOvoid swo_init(){ uint32_t SWOSpeed = SWO_SPEED; uint32_t SWOPrescaler = (SystemCoreClock / SWOSpeed) - 1; // SWOSpeed in Hz CoreDebug->DEMCR = CoreDebug_DEMCR_TRC...
Posted on February 13, 2014 at 05:31I am using a STM32F405RG as a USB host. I've implemented the ST USB Host library (version 2.1.0) in a way that supports multiple devices behind a hub. In order to seemingly support unlimited devices (as much as po...
Posted on February 13, 2014 at 01:04Hi all,I'm looking for the LCD library for stm32l-discovery board, but could not find it on ST website.... I knew someone has used it before, but I'd like to know the original source of it. Could someone point it...
