Hello Jack, according to my knowledge the TB6612 should be able to handle 3V input signals very well. Please note that you have VCC for the logic ( VCC can be 2.7V to 5.5V ) and you have VM for the motor ( VM ranges from 4.5V to about 13.5V )
Connect the 3.3V from IOIO to the VCC of TB6612. Use standard digital outputs ( no open drain, no pull-up ) and it should be ok. best regards Schnee On Saturday, May 24, 2014 12:28:03 PM UTC+2, jack wrote: > > thank you! it can output 3.3V now ,but still can't output 5V > i use ioio_.openDigitalOutput(1, DigitalOutput.Spec.Mode.OPEN_DRAIN, > true); > is it correct? > > > jack於 2014年5月24日星期六UTC+8上午10時56分56秒寫道： >> >> Hello, i'm trying to use IOIO-otg board drive DCmotor by driver tb6612fng. >> Unfortunately,it didn't work,and i found that the pin didn't output >> neither 3.3v nor 5v, i have no idea how to fix it. >> Please help me!!! >> Thank you very much!! >> >> And here is my source code,my IOIOlib is IOIO0503 >> >> -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
