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...
Hi,I wan't to use the stm32 as described in the videohttps://youtu.be/dd5LaqmN8O0https://controllerstech.com/stm32-timers-9-one-pulse-mode/with the difference that I uses the trm4 and the input trigger is channel 1.Operation is ok but applying the s...
Hi,I'm using Nucleo H7A3ZI-Q board and I'm trying to use HAL_UART_Transmit function to print hello world in serial monitor(on puTTy). Code is building without any issues but there's no characters showing in serial monitor, I tried the same code on H...
