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...
Hi,I have posted this question in the following thread but have not received a response yet, so I thought I'd start a new thread.https://community.st.com/s/question/0D53W00000j7Em9/bl462ecell1-not-connecting-to-truphone?t=1624322186588My question con...
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...
In my program I have to change the mode of 2 pin very frequently, I have to get from Input mode (to have an "high impedance" state) to output mode (to use a PP) etc. These pins are PA6 and PA7.And it's working, no problems to do that, I just use the ...
By learning from example STM32Cube_FW_L4_V1.15.1\Projects\32L496GDISCOVERY\Examples\FMC\FMC_SRAM, I tried to setup a simple SRAM program in STM32CubeIDE 1.7.0.When I was asked if I want to init peripheral or not , I select YES. Then I changed Clock ...
RM440 Rev 5 says : "SS can be larger than PREDIV_S only after a shift operation. In that case, the correct time/date is one second less than as indicated by RTC_TR/RTC_DR"Low Layer Driver documentation says: "==> Seconds fraction ratio * time_unit= ...
