I need to generate PWM signals with adjustable number and frequency to drive a step motor. I expect the frequency ranges from 50Hz to 200KHz and the pulses count ranges from 1 to 2k. I have tried 3 different ways including: using timer interrupt to c...
Hello guys,Please find the question which I asked in stack overflowhttps://stackoverflow.com/questions/74422745/i-cannot-see-the-initialized-variable-value-in-the-flash-when-using-stm32
Hi. I made a project with stm32H743IIT6.i used ( touchgfx designer 4.20.0 ) + ( stm32cubeide 1.10.0 )and I saved my images on external flash (W25Q256) with QuadSPI and use SDRAM for touchgfx buffer.But I have a problem. when I display the image on LC...
I want to do a pc waveform display of a four channel adc, it is a serial input pc and the sampling frequency is 1kSPS. What software should I use to develop, the sampling frequency is 2kSPS. I use node-red to find that the chart keeps crashing and ca...
