Is it safe to use memcpy() in an ISR when another memcpy() was already running on main thread or another ISR?I am getting conflicting info on web about using memcpy() in an ISR to copy data between two uint32_t buffers.MCU: STM32H723CubeIDE V: 1.16.0
Hi everyone,I'm encountering an issue with generating a 1 MHz sine wave using the DAC, TIM, and DMA for DDS. I'm utilizing a wave table to generate the sine wave.Currently, I have the HCLK and APB2 clocks both set to 180 MHz, and I'm using TIM8 as th...
Hi,we are using STM32F030CCT6 MCU and the communication is with SWD.for debugging we are using ST link v2 debugger, when we connect the target we are unable to connect. and it is displaying the target not detecting it.need help on this, I am attachin...
Objective:Use ethernet cable to talk to MCU.Don't want RTOS, just want to use simple CAT5e cable to link to PC server and can ping and can send some messages to and from server via JSON format messages.I have swept through nearly all available thread...
Hello,I'm trying to use the HW JPEG decoder on an STM32H743 MCU. When looking at the AN4996 Application Note, I found the following table:However, I'm unable to come even close to these values... This is what I measured: JPEG decodeDMA2D YCbCr320x240...
I have an STM32U83C-DK board and downloaded the git repository GitHub - STMicroelectronics/STM32CubeU0: STM32Cube MCU Full Package for the STM32U0 series - (HAL + LL Drivers, CMSIS Core, CMSIS Device, MW libraries plus a set of Projects running on al...
I Created a New Project for the Following MCU'sSTM32L072CZYSTM32F103C8T6STM32F401REI enabled the USB as Device and Also Selected Virtual Com Port as the Middleware and Generated the Project.Upon Loading the Respective Projects to the MCU's The USB Po...
I tried to solve the questions that occurred during the development of STM32 L4 Series through Googling, but I couldn't find anything related, so I'm leaving a post. I understand that even if the built-in Pull Up or Pull Down circuit is enabled, ther...
We are using STM32L433RBT6 64-LQFP in one of the projects. When we trying to communicate to PC through USB port, USB is not detected in PC, it shows error in device manager (error image is attached for your reference).Also find the USB schematics ima...
Hi all,I am trying to implement a dual active bridge in three phase system. You need one three phase PWM system on the primary and second three phase PWM system on the secondary. Phase shift of PWMs within primary are fixed 120 deg. Same on the secon...
