Once again I'm struggling to find a clear source for a peripherals clock with STM32 MCU's.Most searching leads me to HCLK/2, so at a max HCLK of 180MHz I get 90MHz.However, looking at there reference manual for the STMF469 I see this:From an example ...
I'm using a STM32L062 MCU to interface a BLE module via UART. I have setup DMA with idle line detection to receive data of unknown packet lengths. I'm receiving packets from the BLE module and the software seems to be working fine. However, I noticed...
Hi, I'm using the NUCLEO-H745ZIQ device, and I'm starting with SPI. I used the "SPI Full Duplex communication with DMA example code" in the repository available from "st" (STM32Cube_FW_H7_V1.10.0 folder). It is giving me the expected output but somet...
Is it possible to set an output to "1" or "0" with an instruction of one cycle?
Hello, ST expertFrom the picture below, it showes that 5V tolerent GPIO connect to VDD_FT through a protection diode. But what is detailed difference between VDD_FT and VDD? BRYang
Hello. In a project with stm32g030 (071) I use two different timers to generate two PWM signals. The triggering of timers and PWM signals is out of phase by 180 degrees. Can I use one DMA buffer to load data into CCMR registers of two different timer...
Hello,I have a problem with pins PC2_C and PC3_C on STM32H7. We have custom board based on this MCU and we want to interface SD card via SPI. We are using these pins: PA9 as SCK, PA0 as CS, PC2_C and PC3_C as MISO and MOSI respectively. I can not ini...
Is it possible to calculate how many clock ticks a function or select block of code will use up?
Hi everyone!I'm using a custom board with an stm32l051 and an lsm6ds3(and two 4.7kohm pull-ups). I am setuping the I2C1 (pins PB7 SDA and PB8 SCL). then I do the IMU setup in which I write some values to control registers on the IMU. then I read the ...
In RM0440, it states that "Generation of a single interrupt request for the DMA1 controller," however looking at the exception vectors indicates that there is a separate interrupt vector for each channel for both DMA 1 and 2. Also the stm32cube libra...
