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...
Good Morning Ladies and Gentlemen, Could you communicate in a short way the size of the contact drill-holes (stm32f411 - CEU) ?The diameter in AWG size would be enough.We also are interested in further documentation-links regarding it. In student wor...
The FDCAN module generates timestamps for sent and received messages, and you can configure it to use TIM3 as the source. Unfortunately, the documentation is rather thin, so I am left with a few questions:Do TIM3 and FDCAN need to run from the same c...
Hi all, The STM32L412xx and RM0394 are quite clear about current use of the micro when in standby mode with LSI-RTC.One thing the docs are not so clear about is the effect of having combined VBATT and VDD pins on the low pin-count packages. With thes...
Hello,I'm having issues with software behaving inconsistently and freezing when I add certain lines, try to access certain variables, etc. I suspect maybe it has something to do with the restricted flash regions in the MCU. Is there any way around ...
The STM32F412 chips have 2 MCO pins:The MCO2 pin can have 4 different source clocks:I've noticed that when I change the source from a default one (SYSCLK) to PLLI2S (PLLI2S not enabled) or HSE (not connected), the power consumption is reduced ~0,5mW....
Hello,in the Reference Manual of STM32H745/755 and STM32H747/757 (RM0399) on page 831:When I write more than two 32 bit words to the CRC data register, how can I ensure the crc unit has enough time for the calculation (the 4 AHB clock cycles) before ...
Hello all,i am facing a problem while wokring with adc on stm32f412rgt6. i am facing problem of adc accuracy i am using 5 analog channel (ADC1_AN1, ADC1_AN10, ADC1_AN11, ADC_AN12, ADC_AN13) in discontinous mode.when i am connecting analog input pin t...
I'm using STM32H573IIK6TR and I download its IBIS simulation model from st.com [stm32h562_563_573_ufbga201.ibs]There are a lot of pin model, but i cannot understand what is the correlaction between the datasheet and ibis model. For example: I'm using...
Hello,I'm trying to set up a micro sd on a nucleo-u575ZI through the sddmc1 with a port of FatFs.I am using a PmodMicroSD all wired up for 4 bits and the card detect on a GPIO.I am testing 3 sd card 16GB, 32GB and 64GB.I have confirmed that all 3 are...
Hello, I am working with a STM32H743 with RTOS and LWIP, using LAN8742 as PHY. I have developed a custom board with this setup and it has been working very well.Now, after almost an year, the new production lot does not work anymore: when the firmwar...
