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...
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
Hello,On STM32F401 is the HAL flash erase a blocking function? (one flash bank, no RAM functions) FLASH_Erase_Sector(idx, FLASH_VOLTAGE_RANGE_3); It's not explicitly stated anywhere. Datasheet says reading the flash while erasing causes stalling, whi...
Hello ! My STM board is STM32-L073RZ. I've had a lot of problem with HC-06, tried to somehow send the command "AT" or "AT\r\n", but I didn't get anything back. The bluetooth wasn't connected to any device because the diode was blinking. - I tried cha...
Hi, I can't program the GPIOs levels don't change and stay in reset mode, what's the problem? I use the HAL STMF4 Maybe you help me please!!! Thanks for the advance! STM32F4 Series
Hello, all, and Happy New Year.I'd like to control the contrast and backlight for an 4x20 LCD display (like the NHD-0420AZ-FL-GBW-33V3) using the programming in the micro-controller, in my case, a STM32L010K4Tx. For instance, I want to control the co...
