Hi, I'm having trouble taking to the ax-12 motors. I have a couple of questions, hopefully someone can answer for me.
I'm trying to use a pic18f27j13 to to send the ttl serial signals to the motors, however the motors doesn't seem to be receiving my signals correctly or at all. Under the manual, page7. It says to hook up the TXD signal to a 74HC126(buffer) and then there is a 5v to 10kohm resistor. Is that 5v and pull resistor necessary if I am sending the signal through the pic already? The pic's EUART signals are at 3.2v.
im applying a 12v to the VDD. and when I turn on the power, the LED only blinks once, is that a bad sign? Am i using too much voltage?
