Hi there!I have two UART devices connected to STM32U575 that run at 1.8 and 3.3V and 115200 baud rate. I am trying to get USART1 working on STM32U575 on PG9 (TX) and PG10(RX) that uses VDDIO2 reference 1.8V and UART4 on PA1(RX) and PA0(TX) that uses ...
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 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 ...
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...
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...
I begin a new project I want to use the PA12 as a ADC input. But the pin is orange and I am unable to activate the mode or channel of the ADC.What is the explanation behind it? How do you explain it?Thanks a lot to all.
Hi I want to sample low voltage signals with STM32L476 so I figured it would be a good option to reduce reference voltage and I found this part in the MCU datasheet: Now I am using ADC in dual mode and sampling 8 bit so it is not too precise for low ...
