Hi everyone!
I need some help. I have this board called IRADK (a picture is attached) which is used to control a speed of a asynchronous motor. It has everything that one needs in order to control a up to 2kW asynchronous motor. The microcontroller used on this board is PIC16F877A. My goal is to control this device (IRADK) using Texas Instrument TMS320F28335 DSP (a picture of it together with appropriate board is attached). So I need to take out my PIC (I love to work with PICs but my teacher gave me this task) and replace it with a TexasI DSP. So I need to connect pins with wires, but the problem is that DSP works with voltage level of 3,3 V and PIC works with voltage level of 5 V. Naturally I need some circuit between these two (IRADK and TI DSP) So my question is? Is it okay to use optocouplers and nothing more than optocouplers? Or one can do something better. Any ideas. Thanks!
