How to understand the relationship between Oversampling and the right bit shifts in Sigma Delta ADC
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...
My STM32H743VI Application Runs to a debug instruction in the start-up code
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...
USB FS Device parse_config_desciptors Error
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...
I2C doesn't work after uploading (only sometimes)
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...
Resolved! Frequency PWM calculation vs real
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...
ADC DMA Doesnt Read Properly [Need Help and Advice]
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...
Cannot get DWT counter running on STM32H750XB (STM32H750-DK) ?
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...
Spi clock is not generated
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...
No TSC option from MCU finder & CubeMX ?
Hi, Dear ST teamSeems I can find filters about ADC/timer/UART..., but no filter for touch sensor?Can we add this for new versions of MCU finder and cubeMX ?, it's useful and important for me Thank you Best regards
