I am trying to flash the memory of the STM32-L43KC (Nucleo-32) MCU with the UART Bootloader. I have connected the TX and RX pins of the board to FTDI USB-RS232 connecter. To boot from the system memory, I have also configured the option bytes accordi...
The reference manual documentation for the onboard temperature sensor for STM32H745, RM0399, chapter 26.4.33 gives a formula for calculating temperature that is only valid when VREF is 3.3 volts, but lacks mention, foot note, etc of any kind that VRE...
I am using NUCLEO-G071RB. I use 2 ADC channels: GPIO analog and internal temperature sensor. I connect the +3.3V to the GPIO analog pin via. potentiometer. The internal temperature looks like it works well (the temperature rises slightly when I put a...
MCU: STM32L471VGT6I am trying to get an SD Card to work for my system. I am using a custom board and I cant share any drawings. However, what I am using for the SD Card:Sd card adapter: https://learn.adafruit.com/adafruit-microsd-spi-sdioSd card: SDH...
Hello. I would like touse TCA9539 use as a GPIO Port Expander with STM32F091RCT6 (IO-EXPANDER-EVM Evaluation board | TI.com). I have enabled I2C2 in STM and connect as follows STM32F091RCT6 SCL------------------------>I2C2_SCL PB10SDA-----...
Using an STM32H5 I recently came across a problem: triggering a hard fault when accessing data in FLASH (read FLASHSIZE_BASE).It turns out in this thread that the ICACHE being validated, it is necessary to configure the MPU to make “uncacheable” the ...
Hi all, I've recently begun playing around with Zephyr and made blinky for a custom board with a STM32H755.To test it, I made a complete chip erase and then I flashed the application to the M7 (i.e., its flash area). I can then attach to a debugger i...
Hi, we are using the MCU STM32H725IGKx (UFBGA176) ADC3 configured as follows. /** Common config */ hadc3.Instance = ADC3; hadc3.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV1; hadc3.Init.Resolution = ADC_RESOLUTION_12B; hadc3.Init.DataAlign = ADC3_...

Hi,We have a STM32L031F6 which is used as an RTC. A weird phenomenon is occurring: when the controller goes to sleep, it only uses 2µA, but after 2 minutes and 40 seconds, it starts consuming 50 to 100µA, depending on the hardware board used. There i...
