STM32G0B0 datasheet DS13565 Rev 3 in Chapter 3.6 Boot modes tells: "• USB on pins PA11/PA12 (except for STM32G0B0KE)" This reads like DFU system bootloader is not available. However AN2606 Rev 64 has no restrictions for DFU bootloader on STM32G0B0. I...
Hi,I'm using stm32f072rbt6 mcu for my project.And I want to write data to my usb flash drive as a txt file.I have researched some tutorials but to do this usually used mcu's such as stm32f767zit6 and these mcu's have USB_OTG_FS feature which my mcu d...
We are working on STM32C071KBU6 In STM example TIM_DMA, I see it uses PA10 - TIM1_CH3 with DMA channel 5, but I could not find anything about this. Anyone know how to find this information? I would like to use different pins but don't know what DMA c...
Hi,I am using an STM32H7 TIM8 unit to generate a PWM signal with a fixed number of pulses. The TIM unit is configured in one-shot mode and the repetition counter is configured to generate the desired number of pulses, after which the timer automatic...
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 ...
