[table=98%][tr][td]When applying DSP, the hardware is generally not a big problem. The main thing is the software and the algorithm! I hope the following essence of DSP operation is of some value! 1. ...
I want to use 1611 to generate a linear frequency modulation signal with f0 of 150KHZ. I don't know if I can use the internal DAC to generate such a high frequency signal, or use the microcontroller t...
I just learned STM8 and encountered a problem when writing PWM complementary output. There is no problem with PWM positive output, but the negative output cannot be PWM. It just keeps a fixed level. I...
Traditional broadcasting systems generally need to be operated manually at a fixed time, and can only realize one-way broadcasting with few functions. Traditional bell ringing equipment has a singl...[Details]
