Why is the ADC on my STM32L431KBU3 distorting the signal input to the ADC at certain signal levels?
I have scope captures of the effect.

Need full-duplex connection to modem UART. Can UART driver be extended?
The UART driver has much code with detailed comments for the the things it can do. However, it should come with a disclaimer "No support for full-duplex" which is the most basic use-case. My application needs full-duplex for connection to a u-blox mo...
Record/Monitor an SPI Conversation
I would like to record/monitor a "3rd party" SPI bus conversation.I have a couple logic analyzers, that work fine on the bench.But i need longer term recording, and i need to do it in an environment without a PC and as small as i can get. And i am tr...
Resolved! Can i do an hexapod with facial recognizer with just a STM?
Hi, for my thesis i'd like to do an hexapod(it'll have like 14 servos) and a camera for facial recognizer. I was thinking about an arduino for the control of the robot and a pi3 for the facial recognizer, and then stm32 came to me. Will I be able to ...
ETB debugging on STM32F769NIH6.
I am trying to launch an ETB debug trace on the STM32F769NIH6 using a SEGGER J-Link Base via Ozone, but I get the error message "ETB not available". The SEGGER documentation implies that the STM32F7xxx supports ETB. The STM32F76xx documentation only...
Dip in analog input voltage during uart rx reception
Hi,we are using STM32F030C8 mcu for our application. The port pin PA3 is configured for UART2 receive operation from a RS-485 transceiver and port pin PA5 is configured as an analog input ADC_IN5 and receives signal from an potentiometer. What we obs...
Getting problem with interfacing STM32 L072Z and MPU6050. Always getting a constant value on I2C Read
Hello Everyone,I am trying to interface MPU6050 with STM32L072Z and while communicating to I2C line I am always getting constant value, bellow is the codevoid Serialprint(char *msg){ uint16_t msg_len = strlen(msg); HAL_UART_Transmit(&huart2, (uint8_t...
stm32l4 MSI PLL-mode (auto trimming with LSE ) stable only when VBAT supply present
Hi All,In our product we have to avoid HSE, so decided to use MSI in PLL mode.The below code snippet works fine for MSI in PLL-mode , when auto-trimmed with LSE.But if the battery is say removed (The battery can get depleted in the field), the accura...
STM32G071 USART Buffer Issue: Receiving last sent buffer (even before USART_Init) at time of restart.
I am using nucleo board to test the functionality of USART2 and i am able to transmit data successfully.Now, whenever i restart the nucleo-board or restart debugging, it Transmits last sent buffer again even though the USART is disabled..I want to ...
LSERDY: long startup delay, when LSE in bypass mode driven by a slow clock
Hi,I've an application where I'd like to use LSE in passive mode driven by a slow (1Hz) signal.When testing bypass mode LSE with slow clocks, I observed long delays between startup (cold start) and LSERDY being set by hardware. When measuring that de...
