Dear Community,When comparing STM32L5x2 line with STM32U5x9 line I had the surprise to read in product selector's view:Supply Current Run Mode (per MHz) typical:- For STM32L5x2: 96- For STM32U5x9: 26Are these numbers correct?If yes, what can exp...
I have to deploy an algorithm with a lightweight deep learning-based approach on a low-power STM System-on-Chip based on an Arm Cortex-M-class MCU or Arm Cortex-A-class MPU. Is there a way to reduce cache-misses or a way to reduce the CPU stalls on c...
Hello Community,I am working on a Vibration Measurement system that will be subjected to lifetime vibrations ranging from 10Hz to 2000Hz at approximately 1g with expected lifetime of 2 years with 16 hours daily vibration & 8 hours of no vibration.I'm...
In the STM32L562 reference manual (RM0438), v7.0, the section 11.6.13 "GPIO register map" is missing the registers MODER and PUPDR (which are documented in the preceding sections).
I noticed this in the NUCLEO-L452RE schematics. The external capacitance added to the ABS25-32.768kHz crystal is 4.3pF. Could someone please explain the reason for this?I've learned from the datasheet of the ABS25-32.768KHz crystal that a capacitance...
Hi.I work on BMS. I want a master-slave topology. I want to use 300 slave cards and 1 master card. This BMS is for automotive. I check ST MCU. I guess, The card should be 10-bit I2C. Because I want 300 Slave cards. So, Can you Help me this subject? W...
I'm trying to port a UART driver from aurdino to STM32. Able to relate all interfaces for aurdino vs STM32 while can't able to map ones for the followingserial.peek()serial.flush()Does HAL have an direct interface as peek() to get the next byte of in...
Using the latest STM32CubeIDE, STM32CubeH5 and NUCLEO-H563ZI with TrustZone disabled.I put a breakpoint at the first instruction in startup in Reset_Handler. The debugger shows in SFRs, SCB->VTOR_S is 0x8000000 (which is my NSBOOTADD) and SCB->VTOR_N...
I have an ADC connected to my MCU using I2S. MCU configured in I2S master receive mode. MCU supplying the ADC with 12MHZ MCLK. MCU sampling freq is 48 KHZ(Actual is 46.875 KHZ), Number of slots are 4, Data size is 16bits and I2S standard protocol. Us...
Hello, I would like to know how to retrieve the acquisition values : INPUT -> ADC -> SAI -> µP like the diagram below : I have a program that works for this : DMA -> SAI -> DAC But this is not the way I would have wanted to make my CODEC work. Do ...
