i m using STM32H7 SPI to interface to external 10-bit ADC, which return a 16-bit data but only the last 10 bit (from LSB) is valid. How can i convert this 10-bit data to float ? and how can i obtain these 10-bit from the 16 bit data, i know i would n...
Hello,I have two 32bit timers running on an STM32F373, TIM2 and TIM5. I have successfully chosen TIM2's prescale and ARR values to generate the 'update' interrupt as I require by using TIM2's prescale set to 0 and modifying the ARR to set a target ...
Posted on May 08, 2018 at 08:45Hello guys,I use the STM32F030R8 as I2C slave with clock stretching. It is able to receive and send data based on interrupts. The transmission of the slave to the master works as long as the master and the slave know t...
It is the first time I use Cion to building a STM32CubeMx Project,But I encounter these problems.
Hello everyone,I created a new project with STM32Cube Version: 1.13.2 on Linux, selected my microcontroller (STM32WB35CCU6A), enabled all peripherals necessary (including USB and SWD, haven’t enabled anything RF related (yet)), and tried to upload my...
Due to engineering requirements, the code is divided into two parts: USB DFU, including encrypted signature verification, and the APP code with header signature file. Currently, there is an attempt to rewrite the flash in the USB DFU orange section f...
I have VREFBUF configured for output to comparator on my board. I see this on MCU Vref+ pin...Is 1.2MHz waveform typical? Are capacitors on Vref+ expected to smooth? I looked for avg closer to 2.5v (VREFBUF_VOLTAGE_SCALE0). How close to 2.5v should t...
So the startup code first sets the stack pointer, and then jumps to SystemInit for early initialization, then copies the initial values of data and zeroes bss region and then kickstarts C startup. Is there anything hardware related that has to be don...
Hi there,We use the I2C peripheral of the STM32H755ZI MCU. We operate the I2C in master mode and normally everything works perfectly.However, sometimes the SCL line is kept low for bit longer during an I2C read operation, using the HAL function "HAL_...
Hello, I'm having an issue to use the Microcontroller debug unit (DBGMCU) on STM32H753. I have got IWDG set up and working as expected and would like to have the IWDG frozen during debugging. I have set the DBG_IIWDG1 (bit 18) of register DBGMCU_APB4...
