I am am trying to assess the accuracy of the input capture measurements by capturing a stable periodic pulse, setting the output compare on another channel of the same timer to the measurement, and then measuring the offset on a scope. It appears the...
Hello,I am using DMAMUX(dm) chaining, that means there are n dm channels and the previous is generating an event for the next dm channel as a sync input. I noticed that there is a latency in the transition of one dm channel to the next one. For examp...
If I want my SPI bus to have the CLOCK line high already before the active-low CHIP_SELECT (ENABLE/) line goes low, is there a way to do that?I'm driving an AD9833 chip which requires at least 5 nsec time after CLOCK high, before ENABLE/ goes low. Lo...
Hi,I am using the STM32L151RCT6 in STM32cube IDE, i need to create MODBUS protocol communication between MCU and other board as slave..Please suggest me any related link for implement this..it will be helpful for me...
When I use STM32Uxx boards with USB device and STM32CubeU5 drivers/libraries - I cannot make use of ADC1.I want to use ADC1 also (not just USB), to measure VCORE and Temperature.It is a SW issue (and it can be fixed), not a HW issue.Details:I use STM...
Hello,I am using an STM32L031G6U6 device. (28-UQFN)Summary: There are 6 ADC channels configured for DMA. After having a nominal voltage (2.9V or less) applied to Channel 0 / ADC_IN0 / Pin 6, and then removing the source, the value remains in the regi...
I am working on a project for my company that would like to use an STM32 processor that can both connect to a camera for capturing video data, and also connect to a 2TB SD card (SDXC) for storing said video data. We're aiming for the videos to be at ...
I'm developing a new project based on STM32G431RB using STM32CubeIDE 14.1.0 on macOSI'm having touble where the program will hang at the first call of HAL_Delay() and digging deeper it's hanging because HAL_GetTick always returns 0It looks like the S...
Hello everyone,I am using an STM32F407G-DISC1 and have a stereo configuration of MEMS microphones. I need to divide the I2S CLK, which is 1 MHz, by two for the PDM CLK. I've attempted the settings recommended in Application Note AN5027, but the frequ...
I am generating a sweep signal (a sine wave whose frequency increases over time) on STM32F4 Discovery board by using a look-up table and changing the Prescaler value of TIM2. Unfortunately, the transition from one frequency to another is not smooth a...
