I use STM32U083RCT6 on (my own) simple development board powered by 3.3V (VDD=VDDA=3.3V). I am using small LCD display glass with 4x8 segments. Initialisation code - the first problemFist problem is that STM32CubeIDE does generates wrong/incomplete i...
Hi,Our team is working on a board that should provide the ability to stream a video from OmniVisions' OV6946 tiny CMOS camera module to a monitor with DVI port https://www.ovt.com/sensors/OV6946We are planning to use OV426 as a convertor into a parra...
Hello,I'd like to have this feature implemented: if no data is to be sent, the I2C peripheral (in the slave mode) should not perform an ACK in case of an address match.Of course, this wouldn't have to be an issue, if, for example, no data is ready, t...
How to calculate the power consumption of STM32H743 from datasheet, theoretically as close as possible to the actual value? What parameters should be considered?Also, I want to calculate the heat generated from MCU -- dissipated power (in W). How to ...
Hi,I have a very strange ADC issue which I am unable to find the root cause to. The symptom is as follows;While performing ADC readings to ADC1 IN1 and ADC2 IN1 consecutively, the readings sometimes differ by more than 32 ADC counts. I perform this c...
Hi I am trying to communicate CAN. I am using two boards Nucleo-G474RE and Nucleo-H755ZI-Q and two MCP2551 as transceiver.On either side, program works for External loop back configuration. ( I did step by step debug to ensure the transmitting data i...
Hello, I'm trying to communicate with a STM32G070CBT6 bootloader, with mixed success. I've forced the chip into bootloader mode by writing a 0xDBFFE1AA to the FLASH option register (by default it was DFFFE1AA). I've verified that this value "stuck", ...
Hello,I'm working with the offset and linearity calibration on an STMH755. My board will run the full calibration at production, save off the resulting offset and linearity calibration constants, and then retrieve and apply them at any new restarts ...
HiI have to connect an STM34 Nucleo board to a TMC2209. I have to setup a single wire UART. Only TX is connected with the TMC board.I transmitted a datagram and when I try to receive the response I get back the initial data I have e sent.Does anybody...
Hello everybody,I'm a newbie on ST processors although I have a deep experience on several other MCU (Microchip on top).I'm using an STM32F051K8T6 with minimal connection (VCC,GND,NRST,SWDIO,SWCLK and a Led) to start developing a porting from an exis...
