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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on February 27, 2015 at 11:43Hi,I am using the micro STM32L151. I am using it as an I2C slave and I am getting Overrun and AF errors.The SCL frequency is 100 KHz. When I used this micro as an I2C Slave at lower SCL frequencies it worked fine....
Posted on February 27, 2015 at 10:21We are using TIM16 for pwm audio output. We want to make it more efficient by using DMA. The DMA triggering is done using TIM6 which controls the rate.I would use a direct access to TIM16 by configuring DMA_Perip...
Posted on February 26, 2015 at 09:35I use cube1.3.0 lwip on STM429. It can work and ping ok in release mode. But in debug mode when I use keil and st-link, it always timeout. I have tried ping and TCP recv/send, it's response 2-3 seconds. Link bel...
Posted on February 26, 2015 at 18:51HI.I have a board with stm32f407. I Have ported UCOSII on it and in one of tasks enable USART3 and its interrupt handler. USART works correct at sending but my probelm is this:I can not recieve any thing on my in...
Posted on February 05, 2015 at 19:44The application is to use a STM32F4, but not allow the core to enter any level of ISR at the time it's supposed to service a TIMER interrupt. The application needs the TIMER events to be repeatable down to clock c...
Posted on February 25, 2015 at 00:53Hi,do you (ST) have in plan to make a small footprint STM32F4xx devices?Like 32 or 48 pins?There are times when you just need a lot of power (FFT, DSP) but not so much pins.Like STM32F446 is a great, but unfortuna...
Posted on January 23, 2015 at 01:57 In the STM32F4xx HAL, file stm32f4xx_hal_adc.c there is this code /* Check if ADC peripheral is disabled in order to enable it and wait during Tstab time the ADC's stabilization */ if((hadc->In...
Posted on November 07, 2014 at 11:22 Hi all! This is my first project with ST micro. I have evaluation board stm32373c-eval. I have generated low level code with STM32cubeMX. I want start SDADC1 triggered by TIMER19 but the SDADC1 start...
Posted on November 04, 2014 at 17:13Hello everybody.I hope someone could help...I work with a STM32L053 and should communicate over I2C with a sensor. I checked the delivered examples from the STM32CubeL0 and can initialise the I2C. But when I send ...
Posted on February 26, 2015 at 14:51Hello, we need to assign an unique 16 bit serial number to our production SMT32F051C6T6 parts.I can't do this by calculating it from the 96 bit UID read from the Unique device ID register because I think that in ...
