STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
Posted on February 09, 2014 at 16:57Hi, I have a problem connecting to a STM32F051K6. I tried to use the Debugger on an STM32F0DISCOVERY-Board. It should be an ST-Link V2. Therefore I disconnected the Jumpers on CN2 and the Soldering bridges on SB19...
