I have a self-powered device. It appears as a USB CDC device /dev/ttyACM0, when plugged into a Linux host. The device port is wired to USB_VBUS, so that pin will only be high when connected to a USB host.I would like to detect the presence of the U...
Hi all,I have the following question related with an issue in LOW power modes in STM32 L4.We have developed a board with a STM32L4+. In this board we set the shutdown mode (by HAL_PWREx_EnterSHUTDOWNMode) and we wake from a wake-up pin (we are using ...
I am attempting to set up an encoder on STM32G431RB using Tim 2 which is 32bit but it is only counting up to a 16bit value and going negative. I looked at the register through SFR and only the first 16 bits are active, is there another setting I need...
I would like to use the ADC3 of the STM32H7 series chip to realize that the voltage is collected once, and then the voltage is collected at a different point (meaning is it necessary to use two channels, because I see several channel choices in there...
Hi All:We have a project to receive pdm microphone based on the STM32L476RG-Nucleo board.We hope to use the SAI to get PDM M1/M2 data vis PDM decoder.The audio clk is 192KHz and the data size is 16 bits in the system.First we used the cube MX to gene...
ADS131E08S: The ADS131E08 stops communicating over SPI in continuous mode after a few seconds and block the SPI communication again. But with a Hardware reset and During this,It works Fine but abnormal values are recorded, and the periode to read val...
Hello,Hope everyone are doing well!Can anyone please provide specific numbers?What is the maximum size(GB/MB) of the micro SD card each STM32 device can support?STM32F407VET6 - SDIO interfaceSTM32F745VET6 - SDMMC interfaceSTM32H745ZIT6 - 2 SDMMC inte...
Here is what I observe:I have an application running that communicates via the CAN bus. With a certain command via CAN the STM32 (STM32F2xx) is put into sleep mode. Thereby I configure the microcontroller to wake up and get an interrupt when activity...
This should be easy but somehow I cannot make it work? I am working with the ADC of my STM23F4 Board trying to read the input from an AC voltage sensor. My previous code was using HAL and it was outputting my desired values (around 2000), but when I ...
Hi All,I have been a little confused about my code and would appreciate some help greatly...I have a basic program where I would like to read the ADC values from a sensor, and transmit them via UART for later signal processing and whatnot.The structu...
