Hi,I am working on a new product. For this I use the STM32H723 µC and the LAN8742Ai PHY from Microchip.Our schematics looks like this:We have a 25 MHz crystal connected to the STM32H723 (HSE). The MCO is configured to HSE. The crystal matches the clo...
I'm using STPM-3PHISOSD for testing with Sigma Delta ADC, but I can't understand the relationship between Oversampling of 800 and right bit shift of 6 in the default GUI. I looked up a lot of STM related materials, but none of them explained. In addi...
When I start my program from the uVision debugger the code runs to a debug instruction in the start-up code.It requires three run push buttons to get it past the debug instruction. The program then works perfectly.This problem only happens when I inc...
Hello,I've enable a USB device as a virtual com port. It works well however sometimes I get the following warning in CubeMX's console when I hit 'debug'. The warning appears after I 'continue' after the first 'HAL_Init' debug break point."libusb: w...
I wrote a little program that reads I2C values with interrupts: The Problem is that sometimes it just doesn't work after uploading. I just have to run it so many times till it works (not changing anything in the code). It seems like its just coincid...
Hi, I would like to understand why I don't have the right frequency on my PWM. I am working on STM32F103RG.I would like to have a 8Khz PWM on Timer 3 channel 1, so I have configure my HSI to 8Mhz. APB2 Timer is set to 8Mhz. Prescaler to 10 and ARR to...
Hi, so previously on other post I've been getting trouble with Poll Conversion of ADC using STM32F4 Discovery Board. Therefore i decided to use DMA instead.I made the program using STM32CUBEMX and Keil uVision to read 5 different channels. All data t...
Hello,I'm trying to enable and read DWT counter from assembly on STM32H750-DK board.My code is :// Register Addresses .equ DEMCR, 0xe000edfc // DEMCR reg .equ DWT_CYCCNT, 0xE0001004 // DWT_CYCCNT reg (RM, pp.3211) .equ DWT_CTR...
Hello, I am trying to generate spi clock(100kz) in stm32g473,but desired output not getting in DSO .I tried to change stm32cubemx configuration then i changed the user code then also not getting desired output.Please help me what changes I needed to...
