I am using an STM32L562VET6Q. My device contains both a (custom) bootloader and an application. The bootloader jumps into the application by reading the address of the Reset_Handler from the application's ISR vector then branching to this address. ...
I am using an STM32L562VET6Q MCU. I have been having issues getting a valid reading from the ADC. The signal is essentially DC (i.e., no fast high frequency measurements) so I conservatively set the ADC sampling time to its maximum. My reference v...
Our product uses an STM32L562VET6Q MCU. We are using an ADC to measure current via a 1ohm resistor. Because the currents are relatively small, I want to use the internal opamp in PGA mode to double the input signal before it is send to the ADC. I ...
Hello,I found an example on the internet of a project but I don't understand the usefulness of using a Timer 7. Could you tell me why ? Thanks in advance. __IO uint32_t usTick; void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { /* Preven...
Hi,I have for dream to be able to create a handheld game console like the PSP when I was younger. It's for this main reason I study electronics.I wonder if there is a kit that help me to understand and learn about the concept of it or something not t...
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 ...
Hello all,I'm using STM32L552 MCU and its I2C peripheral to control a board. I'm facing a phenomenal which I not quite sure how to handle that. I have a pretty old fan controller chip on the board which is kind of really slow. Not only it works with ...
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...
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...
