What is the maximum UART speed on the STM32H7B0xB?

I'm looking at the STM32H7B0xB. I'm confused about what the actual maximum baud rate of the UART (in asynchronous mode) is. I'm getting three conflicting answers:Section 3.38 (the USART section of the datasheet) says: "These interfaces provide asynch...

Resolved! Built In LED Stopped Working

Hello,I was using STM32 Blue Pill board and it was working fine until few hours ago. It suddenly stopped working. I was trying to make the built-in LED (At PC13) blink using Arduino IDE but it's not even blinking when i do Reset now. I've tried Flash...

STM32G051 ADC Calibration issue

Hi I am using the STM23G051C8T6 for the internal RTC and an external battery on Vbat. I noticed if I perform the Calibration using the following lineHAL_ADCEx_Calibration_Start(&hadc1);my initial ADC reading will be lower then actual reading. For exa...

I'm out before I even really got started...

Hopefully someone at STE cares enough to take this honest feedback on board...My project had to move from atmel to something with more performance.  I settled on STM32.The experience has been terrible due to sub-optimal documentation from STE, relyin...

Is HAL_I2C_GetState() required in polling IO mode?

I am using the HAL library with an STM32L07xx processor. To keep things simple, I have implemented master transfers on the I2C bus in the polling IO mode. Most of the time it seems to work, however once in a while a master transmit seems to get lost....

Resolved! STM32L4 FreeRTOS vs Bare metal performance

Hi, I have an STM32L4x6 processor.I'm reading data using ADC and DMA, and after the HAL_ADC_ConvCpltCallback, I process the data with a Fast Fourier Transform. Originally, in bare-metal, I had a flag in the main loop, and when the interrupt occurred,...
