In the single-port DMA, transfer units (to which requests correspond) are called Channels and they are numbered 1-based.In the dual-port DMA, transfer units are called Streams and they are numbered 0-based.DMAMUX documentation in various STM32 models...
Hi Experts,May I know is there any speed different between access direct to Peripheral Register like, GPIOx_IDR? with access directly to SRAM ( using DMA to do Peripheral to Memory)?From this block diagram, the GPIOx_IDR is using AHB1 bus and it runs...
Hi all, I am trying to implement a frequency counter using an STM32F446 and STM32CubeIDE. I am following the reciprocal measurement approach of one STM32 tutorial available in internet (see screenshot). Basically, i am using the input capture mode t...
Posted on December 06, 2016 at 19:53 Hello, I have managed to create a program (using Keil), that can turn LED's on and off based on the orientation of the MCU. However when i try to implement the program as an RTOS with threads, the program d...
Good day guys I am trying to learn the delay to activate output. I found a tutorial on the timer delay. I defined the delay as 5ms. I found that the code works on a single GPIO.Now I wanted to activate 2 GPIOs with each having their own 5ms delay....
I've been able to figure out how to do basic interrupt and DMA I/O on both STM32L4 and STM32F4 UARTs with the HAL Library. But I'd sure like to figure out how to do this without the burden of the HAL libraries. Can someone point me at a complete ex...
I am using STM32H7531-EVAL Rev1. Board. I am trying to run the given example for NOR FLASH i.e PC28F128M29EWLA to read and write data to Nor Flash memory.I was successfully able to read the NOR ID, But when i am tying to write and read back from flas...
I am currently coding on a board developed with STM32F030, and I ran into a stupid problem.Currently, there is usart (A: serial communication) to communicate with the module.To test this, we connected to usart (B: serial communication) set as the de...
Hi all.i try to understand the power consumption of the ADC VS FREQ.according to the DS and the REF_MANUAL , the Power consumption is 1.8uA/MHz ( in the Clock Domain ) ,the ADC working on SYSCLK , MSI for Eg..there is an option to divide the ADC Cloc...
Hi all.i using the ADC in STM32L412 MCU .according to the DS , the current consumption of the ADC in Range 2 is 0.2uA/MHz for independent clock domain and 1.8uA/MHz for clock domain...what is the "independent clock domain" according to the DS , the...
