Once I switch to the HSI clock source and switch back to MSI my sleep current increases from 25uA to 500uA. Maybe HSI is turning something on that the MSI configuration is not turning off. I can't find it. Any help is greatly appreciated. Doug
I am using STM32F401 for audio acquisition through I2S interface and also interfaced an IMU sensor with the MCU through I2C. I am using the CCA02M2 library provided by STM for audio acquisition and a separate task for reading IMU data. When I run the...
Hi,I want to implement button interrupt with time period to send the mcu to Dee-sleep ,and wake up. For example; When I press button for 5 sec, MCU will go to sleep, when I press the button second time for 5 sec MCU will wakes up. but I don't know ...
Hello All,I'm using a STM32H743, and I would like on runtime from a GPIO IT, restart to zero the counter period of a timer, is it possible ?How to do that ? I havn't found API for that.Thanks.
Hi All, I would like to send int32_t decimal number via USART, but with HAL_Uart_Transmit we can send uint_8. Do you have any idea how I can do that?Thanks.
stm32f730 , Quad SPI ,i used to communicate to a device ,need 3bits data width. but how to configure the data shift out on the rising edge of clk and sample the falling edge . like the Stand SPI , we can set CPOL to '0' or '1'?if not to do , pls ...
HI ,My question is STM32L4 goto sleep (STOP2 mode). I found ADC function is not working when MCU wakup.If not goto sleep ADC is working well.
