I read in reference manual and web tutorials of stm32f103c8, there were "AHB", "AHB1" and "AHB2", what's the difference between them, I know "APB1" and "APB2" are 2 APBs, the "1" and "2" are sequential numbers, how about "AHB1" and "AHB2" are they al...
Hi everyone! I'm using two uC, STM32F105VCT7TR and MSP430G2452, and I'm establishong an I2C communication between them, with the STM32F105 being the master and MSP430 the slave. For the write operation, the communication works fine. However, when per...
Hi,I am working in STM32F4 Discovery, in my project I want more GPIO pins but with Same registers so that I can straight away copy the old programs and do programming, Is there any suggestion Please do let me know. Thanks,Mohan
Hi all,I'm using a Timer in Encoder Mode on STM32F103, using the HAL framework on STM32CubeIDE.I would like to change encoder filter feature (IC1F[3:0]: Input capture 1 filter) depending on the behaviour selected in my MCU operation mode (so IC1Filte...
I'm trying to implement a SPI transfer between flash and SPI2 - a simple display. I'm using LL everywhere.No problem with M3 and M4 - But GPDMA is completely different. "Normal" SPI work but no way to enable DMA.Based on the only example with LL (All...
Hello, I can't see exposed die pads on STM32G491KCU6 and KEU6. Is this okay to use? Are they thermally limited for use? Thank you.
Hi,I am working with STM32G4 and I have problem reading/writing the I2C data with in the timer callback.I have Timer1 calling my interrupt callback every 50 microseconds which is working well.I have I2C read/write functions which are working well.I2...
Now I'm using the "STM32G491CCU6" MCU.It uses 5 and 4 channels of ADC1 and ADC2, respectively, while also using DMA.However, I configured it to use Rank and make DMA interrupt, and when writing code through STM32CubeIDE, I set "HAL_ADC_Start_DMA" and...
Somehow this is not right, or i got it wrong?
Just wondering if anyone has information on how to sync external ADC and DAC conversions?The ADC and DAC are connected as SPI peripherals (separate SPI's) to an STM32G474RE.The system needs to run in continuous mode with a configurable delay between ...
