Heyho,I'm using a H733 with both SAI 1 and SAI 4 with SAI 1 as I2S clock master to get 8 synced audio channels.Audio clock comes from I2SCKIN, this is used for SAIs and I2S.Problem: because of the fixed oversampling ratio (256 or 512) of the SAI, I h...
I saw the following function in the USB library.uint32_t USB_OTG_GetEPStatus(USB_OTG_CORE_HANDLE *pdev ,USB_OTG_EP *ep) { ·········· if (depctl.b.stall == 1) { Status = USB_OTG_EP_TX_STALL; } e...
Nucleo-G431 onboard stlink used normally before, but recently it suddenly couldn't be used, there was no response when connected to the computer with a USB cable, the computer could not detect the stlink (it can be determined that there is no problem...
Hi, I am using STM32U575 MCU and implementing firmware upgrade feature in it using the ROM bootloader. The application code boots the bootloader by calling the following function. The firmware upgrades correctly and I verified that all the bytes are ...
I have configured the timer clock to 170MHz. According to the datasheet, the maximum fENC value is 42.5MHz when the timer clock is 170MHz, and the tW is specified as 2~3Tck.I am using a quadrature encoder with two channels that provides 1024 pulses ...
(Updated: I just noticed I initially wrote LVDS instead of DSI - corrected now)Hi,first time working with animated graphics and video on STM32, what is the best way to select a micro family for graphic application? I could not find a selector tool th...
Hi STM32 guys/gals,The gray/white signal is for reference only, and that's the signal I'd like the generated yellow signal to achieve when starts and stops. I'm using DMA in circular mode to generate the yellow signal. However, I'm struggling to comm...
Hi,I am trying to implement USB HS based on the USB PHY USB3300 (using board waveshare USB3300 ULPI) and STM32F446ZE (using Nucleo STM32F446ZE). I am using code sample from STM cube to run the trials. Board are connected with short wires (as short as...
Posted on April 07, 2012 at 22:52Hi, I've been trying to write some code, but I'm running into a bus fault. I'm new to programming, especially with regards to microcontrollers/stm32, so I don't really know how to debug efficiently. I'm using Keil uV...
Hello Team,We are using STM32H573AIIQ in our application. We are using SMPS to power the core supply. we have used external inductors and capacitors as per datasheet recommendations.When we tested the core supply, during power up, there is a overshoo...
