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...
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 ...
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...
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...
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...
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...
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 ...
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...
Hello,I am currently using a STM32F429ZI-DISC1 Discovery Board.I tried to get a UART tranmission going through CubeMX/HAL Drivers. Transmitting data works perfectly fine but when trying to receive any data I don't have any chance. So I was looking ov...
Hello, maybe it's not the right place to ask this type of questions, in case I apologize.While trying to understand how ARM assembler works, I came across this problem and I'm currently struggling to find the answer.Before explaining better my questi...
