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 August 19, 2014 at 13:45I've been looking through STM32 development board circuits to find the best way to connect the USB disconnect. I found the above circuit from the STM3210E-EVAL board, but all of the ST boards appear to have similar ...
Posted on August 14, 2014 at 18:46hi, I'm novice with STM32CubeMX HAL + FreeRTOS with KEIL MDK-ARM ulink2 I have problems, with SysTick probably, HAL_RCC_ClockConfig, because it genere HardFault_Handler. When xPortSysTickHandler() in SysTic...
Posted on August 18, 2014 at 23:20Hello,First of all, In a PIC32 environment, I usually fix a value for the heap somewhere in the IDE project settings, do I have to consider this while working with Atollic and STM32F4 ?I am new to STM32 MCU's and I ...
Posted on August 15, 2014 at 18:56Dear friends. Show me please my mistake. When I debug the following program I even cannot get to ISR... I stay in infinite loop... Thanks! void EXTI0_IRQHandler (void); int main(void) { /*!< At this stage the micr...
Posted on August 19, 2014 at 01:01Hi, I am not able to clear a timer update flag while the timer is enabled. I am initializing a timer and the behavior is the following: .... TIM_TimeBaseInit(TIM4, &TIM_TimeBaseStructure); TIM4->SR = (ui...
Posted on August 13, 2014 at 00:06Hello.I'm following the procedure in AN2604 and trying to use an internal timer to measure the rtc frequency by looping back the rtc into a timer pin, in my case PA8 (Timer 1 channel 1), and then using PWM input cap...
Posted on August 18, 2014 at 18:11 Hi, I want to communicate with an i2c eeprom, I am able to send the first data but not the second. it seems that the buffer is full or there is another error somewere. Does anyone have an idea? #inclu...
Posted on August 18, 2014 at 16:20Hello,I'm discovering the STM32F407 with an STM32F4Discovery, in the past, I worked with a PIC32, and I see that there is many differences between those two microcontrollers.I want to understand how the UART periphe...
Posted on August 18, 2014 at 16:17So this maybe a very stupid and noob question: Are the library functions of stm32f4 and stm32f3 the same? I have been working on stm32f4 for quiet a while and had written a large amount of code for a certain project...
Posted on August 18, 2014 at 13:33Hello,How to find out what are the frequencies possible on I2C,SPI,UART buses of STM32F051xx? How to calculate the cross talk coefficient of these buses if the tracks corresponding to them are .2mm wide and are .3mm...
