I'm trying to run a motor controller board (rover 5) and the 'direction' pin needs to be 0V or 5V. I wired it open drain with a 10k resistor to 5V power and the IOIO can pull it low, but it will not go high to 5V with that resistor. I'll have to use a lower ohm resistor to pull it up, apparently. But I am concerned, the IOIO will probably have to be able to sink about as much current as the motor controller pin will draw at 5V.
How much is the max in open drain? Is it 20ma? What can I conveniently do if the pin requires more? -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
