ADC Data extraction at high sampling frequency
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...
Resolved! Need Guidance on QSPI External Loader Issue with Custom Board Using STM32H750
We are currently working on a project using the STM32H750IBT6 microcontroller interfaced with a single-bank Quad SPI NOR Flash (MT25QL512ABB) on our custom board. The QSPI interface is operational.However, we are facing an issue with the external loa...
"Optimized Resolution" options in CUBE ADC
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...
sm32h7 firmware only running after reset
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...
Resolved! STM32H7 USB VBUS sensing question
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...
STM32N6 XIP with Quad spi
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...
HMD Application -STM32F1 with BNO055 Via VCP
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...
possible defect and fix for HAL SMBUS interrupt processing
Hello,I am using the HAL for multi-master SMBUS operations on an STM32H753. I ran into a scenario in which the event handler interrupt function (I2C4_EV_IRQHandler() in my case) was repeatedly firing such that there was no CPU available for other cod...
Resolved! STM32H7R3 PSSI RDY/DE bug
Hello,I dug deeper into PSSI behavior, and and I observed unwanted behavior. From my point of view it is a bug.PSSI is configured as:OUTEN = 1 (transmit mode)CKPOL = 0 (outputs driven on rising edge, inputs sampled on falling edge)RDYPOL = 0 (0 at in...
