Hello, I have an application where originally the STM32G071GB (128K) was designed in. Unfortunately there was no available stock of the STM32G071GB (128K). Compiling our code was slightly over the 64K when no optimization was used. Enabling optimi...
I am reading RM0390 and have been finding a lot of mistakes in the CAN section. Who do I tell about them? Is there an email address or a form?
Hi,I am new with the STM32H7 timer/counter. I found the LPTIM_PulseCounter example which was good starting point. But I have a couple of questions:How can a reset the counter manually (not via automatic reload) of LPTIMER1? I could not find any HAL_L...
Hey guys,just playing here with the STM32H743 and it's SAI interaces. Works as expected, but from the datasheet the only supported oversampling factors for MCLK are 256 and 512. Especially for higher samplerates with high quality ADC thoose oversampl...
According to RM, "The I2C detects its own SCL low level after a tSYNC1 delay depending on the SCL falling edge", andi2sT=1/i2sclktSCL=tSYNC1+tSYNC2+((SCLH+1)+(SCLL+1))*(PRESC+1)*i2sTfSCL=1/tSCLI tried different PLL clock configurations and altered au...
Hello, is possible to buy a manufactured case for Nucleo-144 boards?Thank you for your response.
Hello folks,Today, I am trying to use SPI communication on my board. I saw that there is a gyroscope on my board. So, I thought it's a good idea to use this device as an example. Since it's already routed it up, I cannot mess up with connections, etc...

hello. I try to run usart1 in stm32F769I-disco. It is declared as : The serial interface USART1 is directly available as a virtual COM port of the PC, connected to the ST-LINK/V2-1 USB connector CN1. I added MX_USART1_UART_Init(HAL_UART_Init) and ca...
