Two STM32 communicating over UART
I have written code for both the transmitter as well as receiver board. The issue is when i see the communication over logic analyzer or even while using TTL to RS232 converter, i can see that the port is continuously occupied and master is transmitt...
STM32F0 TIMER PWM DMA not working.
i want change pwm duty cycle using dma in circular mode but its not changing duty cycle so dma is not working what is the problem in code? how can use PWM + DMA ?main.cuint16_t duty[] = {0,100,200,300,400,500,600,700,800,900,1000,900,800,700,600,500...
Resolved! Problem with USB OTG in host mode, no HOST_USER_CLASS_ACTIVE.
I configured USB_OTG_FS on STM32H745I-DISCO board using STM32CubeIDE.Here are my settings:My `MX_USB_HOST_Init()` function is called in `DefaultTask`.It completes without errors.`USBH_UserProcess()` is called whenever a USB disk is inserted to the po...
An SPI problem on NUCLEO-U575
Hello everybody!Running into a weird problem with SPI. A super simple code, which runs once a second and sends a 16-bit number over SPI. If I leave the TSIZE field in CR2 at zero - everything is okay. However, if I write any number in the TSIZE, then...
STM32G484QET6 Pin File
I need a pin file for the STM32G484QET6 with the die to lead frame distance through bond wire etc. and die to lead frame delay. Where do I find this?
Using accelerometer IIS3DWB
Hello all, I am trying to read the temperature out of the IIS3DWB chip and I am following the github example (iis3dwb_reg.c). My code is given below.However, once I start running the programme, the temperature I am measuring in degrees Celsius doe...
STM32H5 Can't initialize i3c device BMI323
I am working off of the example I3C_Controller_ENTDAA_IT for the STM32H5 series to initialize a device (BMI323 IMU). I am hitting an error handler at the HAL_I3C_ErrorCallback before it tries to add the device on the bus.The SER value at the HAL_I3C_...
Resolved! Hardware JPEG Codec in STM32U5Fx/5Gx
In your document AN5766 Migrating within STM32U5 series microcontrollers.You mention that the JPEG Codec will be available in STM32U5Fx/5Gx. i try find this microcontroller in the Cube IDE but cant.do u have info about it or datasheet for it?RegardsM...
Resolved! ADC fails to start on STM32U575 (Nucleo-U575ZI-Q)
I have a very simple ADC setup for one-time conversion, only one Vrefint channel enabled, no DMA, ADC clock is 16MHz, MX_ADC4_Init() called with no error.HAL_ADC_Start() fails due to a timeout internally waiting for ADC_FLAG_RDY to be set in ADC_Enab...
