Dear All,

I want to use ST7 MCU in my project.

I need to Generate 50kHZ, for tranducer (ultrasonic), which means I need to generate 50kHz sin-wave.

1) Can I use I/O to generate 50kHz sin-wave?

(AN1041 is not enough, 100hz max)

2) If no MCU can do that function. Is it any component can be added to do the function?

Thank you very much, and best regards.

Lailun

You can refer another application on this subject AN1712(Generating a High resolution Sine wave using ST7 PWMART). It makes use of PWMART for genration of PWM.
