hello everybody I am programming 10 addressable Leds with PWM with DMA using the M7 cortex of an STM32H747 in a custom board.Characteristics:Clocks: SysClk 480 MHz, TIM kernel clock 240 MHzTimer: TIM3, Channel 4, internal clockPWM base frequency: ~77...
Code is written using stm32CubeMX. Connecting with stmlink V3 Minie. Executing step by step, it appears that debug fails (lose connection) when executing debug_init. In fact debug_init creates the problem when programming pa13.When removing the initi...
Hello,I have an STM32G441 and using DMA to transmit some SPI data. All works so far. The problem is the chipselect. I am using the software chipselect. So before I start the DMA I pull CS low. Then when the DMA complete interrupt fires I pull it high...
I noticed some options in the CUBE IDE for my H745's ADCs labelled "ADC 12-bit optimized resolution" and likewise for 14 bits. I have searched the references and the internet and find no explanation of how "optimized resolution" differs from the regu...
hi guys , I have been working on a stm32 project like a digital automotive cluster using STM32H7A3ViT6 MCU . I am using the LTDC module to drive the display . now the problem is the mcu dosent run the code on powerup but it ll do when i press the res...
We are using an STM32G070 with 64 Pins.The clock comes from an external 32,...kHz crystal. For clock calibration, we enable the RTC calibration output PC13.Whenever this is active, reading the state of the input PA4 always returns false, although we ...
I am using the USB OTG FS on the STM32H7. My MCU is self powered, so I need to use VBUS sensing. Can a 3.3V signal be used for the VBUS sensing on PA9 or must it be 5V? Based on the linked forum, I believe 3.3V would work, but would like to confirm w...
ST moderator: Edited the tile to add "ADC" I want to extract data at high sampling frequency ~10KHz at STM32N6570-DK, Is it possible with USART for three channels or we have any other mode for this purpose. I want to continuously stream data at 10KHz...
We have both a very RAM constrained and space constrained board. So the OctoFlash chips are larger then i would like. So being able to XIP off a spi flash that only has 4 SPI lanes would be very helpful. I just don't know the ramifications of som...
Hi, I use the stm32f103 to read the IMU(BNO055) via I2C to get the Quaternion data,I use this library from ivyknob, https://github.com/ivyknob/bno055_stm32The AR Anchors result is well (Head Mount Display application), I use the USB VCP to Transmit t...
