Hello to everyonesIn a project where I used the STM32G0B1RTC6 MCU I have the following problem:The PA2 pin used as uart2 TX sometimes goes low at power on and stays there forevereven if I try to reset the CPU again. If it is configured regularly then...
Hi,[NOTE : this message has several parts, because it took me time to write, time to check what I wrote, time to check again "The Internet", just in case. And guess what : I found some solutions to some of the problems. But I prefer to share my whole...
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 ...
