Hello,i try to implement a 40kHz frequency burst with my NULCEO STM32F411RE. Until now i toggle the GPIO continuously in the HAL_TIM_PWM_PulseFinishedCallback function. But now i have to implement a start Trigger to do a small 40kHz burst. In the att...

Hi there,i finished my program and the schematic design of my prototype. Now i want to start with the PCB layout. Therefore i have some questions regarding the Supply & Oscillators. At the beginning i implemented the DFU for programming the STM32F4, ...

Hello,i am using a Nucleo - F411RE board and i want to create a sine wave with an external DAC (mcp4922). So i initialized a SPI connection to send my sine wave table to the external DAC. The frequency of the ouput sine wave should have 40 KHz. At ...

I am trying to Convert my code, running on a NUCLEO F411RE Board to a NUCLEO L053R8 Board.There is a Datasheet "AN5044", so i followed the instructions. I choosed the source directory and the destination directory and started the convertion. I got 77...

Hello,to finish my project i want to remove my the cable wich is plugged in to my PC. So i need an external power supply. In the Datasheet i found the topic "external power supply" but i still dont know how to connect it. It says that i have to use E...
