    Custom baud rate on 14M2 to read Renix-ECU.

    Hi guys, here we are with a new question, I'm working to a new project, but before start to do something i must clarify a few things. The project plans to read with a 14M2 picaxe the serial out of the main board of my car, and after processed the data show the value on a lcd display. The car is...

    Yaesu's serial protocol.

    this is my circuit ft847 is equipped with a 232 converter, so i inverted the signals by 2 optocoupler, i think my connection polarity is working well because the rig receive the command by 14M2. Is the 14M2 that don't receive the right data from the rig. I would like to try to analyze the...

    Negative current.

    Hi guys, Does anybody know the maximum negative current of an input of a Picaxe 08M2 ? I mean to connect for example a diode led anode to supply (5 Vdc), the cathode to a resistor and than to the input of my Picaxe and light up the led when the input pin is in low condition. I know the maximum...
