Hi there,this is my first post here. So be gentle with me ;)I been working on a project with STM32H757XIH6 for some time now, but without any success. This is already my 2nd prototype and costed me quite some $$ since it had to be a 8 layer PCB. The ...
Hi everyone,1, What are the acceptable buffer sizes for the DFSDM PDM mic configuration, give me some examples?2, Can I use ( int32_t buffer[4000] ) for the PDM buffer?3, How do I sync different sensors with the DFSDM PDM mic?
Hello,I'm a hobbyist and I'm working on a USB to 4xI2S (8 channels using the SAIs) using a stm32H7 MCU. I have a proof of concept working on a stm32F7 discovery board. I'm starting to look at the dedicated board.I understand that the USB peripheral n...
Hello,I'm using the nucleo-h743zi2 board.I am trying to use the USB OTG FS function.The .IOC file settings are as follows:USB_OTG_FS enabledMODE: DEVICE_ONLYVBUS: disableuncheck SOFI provided power through an external source and also swapped the D+ a...
I'm having some trouble performing a bank-swap on an STM32H745. The function works perfectly fine on an H743, but when porting over to the H745, it doesn't run the firmware that was swapped in.Firmware 1: prints "1.0". A button press will trigger a b...
Hi, I am unable to communicate via i2c with the TLV320AIC3104IRHBR chip, the bus response is always busy. I'm just using the STM's internal pullup, I check it on the oscilloscope and the pins are high but no communication happens. Below is my i2c con...
Hi Folks, I am using a STM32F070F6P6 microcontroller for a very basic/simple project to help learn the STM32 platform, etc.I am getting an error when I attempt to build my project that my code overflows FLASH memory by quite a bit. I did a test on a...
Posted on October 28, 2015 at 23:27Hi,In my design I'm using an external 24.576 MHz oscilator as I2S clock sourceAcoording to the reference manual, for 32 bit frames and MCLK output:FS = I2SxCLK / [(32*2)*((2*I2SDIV)+ODD)*4)] For Fs = 96 KHz, this g...
Dear all, I'm working on a project with a waveshare eink display. I'm using the STM32F103RET6 controller and CubeIDE as development environment. I'm building my application as a c++ application with the FreeRTOS lib. My Display class has a 4000 byte ...
Colleagues,What should be done in firmware for VBUS detection through a GPIO pin? My device is self-powered, so I have to do VBUS detection. The device is built around STM32G474, and it doesn’t have a dedicated pin for VBUS detection, so I have to d...
