I'm using the STM32G030FP6 in standby mode with WKUP2 for wakeup and the system has a backup battery. I'm facing the following issues:When using the LSI clock, standby entry and WKUP2 wakeup work normally.When using the LSE clock, after entering stan...
I am using the STMG0B1RET on a custom, battery-powered board. During normal operation pin PC4 is used as UART1 (with an external pull-up resistor). In Standby Mode pin PC4 must be LOW in order to shut down the external device. For this I convert PC4 ...
I am running code on an STM32U585QI that enters STOP2 when the code is idle. I am disabling the data cache before going to stop2, and enabling it when coming out (to deal with an errata item). My code basically does this:HAL_DCACHE_DeInit(); HAL_P...
Hi,We are using an ESP32-S3 device as the I2C master to communicate with STM32G070CBT processors operating in I2C bootloader mode. We have two revisions (Revision B and Revision Y) of the STM32G070CBT processors.When probing the STM32 I2C bootloader ...
I am studying the architecture of the STM32H7 family, and according to the AN there are various types of memory, DRAM, SDRAM, NOR/PSRAM, NAND in addition to the swap between SDRAM and NOR/PSRAM.What is the reason for such diversity and what benefits...
Hi,I am using an STM32L476 on Nucleo64 board, I am amplifying a 1MHz 200mVpp sine wave with a 100mV offset in order to try the OPAMP but I dont think it is working. I configured OPAMP in PGA not connected mode(Also tried PGA connected too) and gave i...
Hello Folks,I am facing the issue regarding the RTC in stm32H7S78-dk evaluation board. So, the issue is if I configure the internal RTC in my IOC file all the other the process stops on my board which is working already like TouchGFX, Ethernet my LCD...
Posted on January 13, 2018 at 20:28I am experiencing ADC inaccuracy around VREF/2 with the STM32L4. Measurement result gets 'stuck' at 2047 for a couple resolution steps, although signal that is measured increases further. At around approx. 2065 and...
I am just wondering how it is possible that 3 adc gave me the very same value, if I change the channel and their rank are different. Thanks for all.
Hi,everyone.I'm use NUCLEO-L496ZG platform.ADC1 sample at a frequency of 5M,ADC3 sample at a frequency of 12.8K(PWM trigger).when only run ADC3,ADC3's waveform is normal.when ADC1 and ADC3 run at the same time,ADC3's waveform has a lot of interferenc...
