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 ...
hi,I want to use CMSIS-DSp library in my stm32h743 project. the project contain USb MSC device also.After adding the library to project i am getting 5 errors, which I am listing below,11:56:50 **** Build of configuration Debug for project DIN_MAIN_V3...
Hi, I found that when STM32H5 entered into CAN bus-off, it couldn't recovery CAN communication by itself. And there is no "Automatic bus-off option" for this MCU. I have read the MCU Manual to know related registers about CAN bus-off for this MCU, bu...
