Hello, I have a set of extended CAN ID's I need to pas the bxCAN filter. I looked at some examples where one ID is passed the filter, but could not figure out how to allow a set of ID's. If my understanding is correct the mask is used to determine wh...
Posted on October 09, 2016 at 20:03Hello,I'm building an application with ST STM32L4 that stores information on internal flash (ECC flash on L4). The information is valuable, so the flash programming must be robust to unexpected shut downs including...
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...
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...
