hey,i am new to stm, recently i was asked to transmit data from uart based on dma instead of using interrupts that uses the cpu resources.are there examples or instruction of how to do it? i am searching for 2 days and cant find somthing usefull.
Hello Everyone,For some reason my STM32F407 MCU with specific board has problematic issues in the start. If I connect 3 different cards to its UART channels, which utilizes DMA, it does not start directly and after a while (which corresponds to 1 sec...
I know TrueSTUDIO is tagged as obsolete, but I like to use it.The STM32H5 use Cortex-M33 core, then how to add M33 support?I already upgraded TrueSTUDIO to support GCC 10.3.1 and recent loaders and SVD files. It would be nice to use M33 cores with Tr...
Hello everybody,I am trying to bit-bang an I2S interface on an STM32F103 at 72MHz using TIM2.Am I way too optimistic to get a 3MHz "clock" out on a pin? The fastest I can seem to get it is at 90kHz.I have set the "prescaler" of TIM2 to "0" and "1".An...
Sir I am doing my final year project and got struck. My project aim is to receive data from the nrf24l01 module which connected with arduino for generating sinewaves this act as TX part. Now in RX part I am using nrf24l01 with STM32f411re and I want ...
When running your PWR_ModeSelection example on a NUCLEO-L496ZG board the current consumption in run range 2, 24MHz depends on the order objects are linked in the executable. When the object_list is in this order:hal/stm32l4xx_hal.ohal/stm32l4xx_hal_...
Hi all,I've got an STM32 evaluation board (STM32H745-DISCO). As soon as I connect the board using the ST-Link connector the Windows PC also detects a mass storage device.I haven't used this feature before but it seems that "drag-and-drop programming"...
I am using STM32G031 where in my application I have to capture the frequency of Input signal from a sensor and then generate an output PWM with frequency which is twice of input frequency. I am using TIM3 to capture the input signal from sensor and c...
Hi. I get a STM32H5 Nucleo board (MB1814) and configured comparator with neccessary settings using CubeIDE and LL library and got next generated piece of code.int main(void) { NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_3); SystemClock_Config...
