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...
Hi everyone ! I read in the datasheet that I need the VREFINT_CAL to calculate my real VDDA but I don't find it in the datasheet. In every other model's datasheet you can find the VREFINT_CAL easily but not in the STM32L0 one. Is someone kno...
I'm trying to use both internal op-amps to sample analog inputs with ADC1 and ADC2. When the op-amps are setup using CubeMX (latest version), 3.3v stays present on PA6 input. PA0 works as expected. Both ADCs sample correctly but the waveform input th...
Hello,we want to build a system with STM32H7, hopefully one of the new up to 480 MHz devices. And we really need a high clock of 400 MHz and above. On the other hand we need low power and we use ADC and DAC, both requiring a 3.3V Vref.Now my question...

Hi there,I'm working with an STM32L073RZ CPU and Mbed OS 5.12.0 and experiencing an issue that I'm not quite sure how to describe. The processor gets into a state whereby it oscillates a pin (PA_5 which is setup as an InterruptIn that pulls down) and...
Using an STM32H753, I have boot code in bank 1, sector 0 (0x08000000) that detects and jumps to application code in bank 2, sector 0 (0x08100000). In the application code I am trying to erase and rewrite bank 1 sector 0, but the MCU locks up (with no...
Dear All,i configured an input pin as external interrupt with rising edge detection and pulled it down internally.i apply a pulse train which it sets and resets within the time that the interrupt is disabled.i expect that the ISR executes when it is ...
Has the MSI with LSE auto calibration a sufficient precision for the 1Mbit CAN bitrate?What is the accuracy compared with a crystal PLL clock?
Posted on December 14, 2016 at 10:27Hello,did anyone ever manage to get PB3 working as an I/O port on an STM32F103?I am having a hard time with the F103VB where I need PB3 as input - no matter what I try, PB3 simply is returning a 0 value.AFIO->MAPR...
