    Adrunio as I2c slave

    Can someone tell me how to use a Picaxe 40x2 as the master on an I2C bus with an Adrunio as the slave. I can write to the Adrunio, but can't read from the Ardunio. Any help would be appreciated. Thanks

    I need to receive unsoliciated serial data from a Windows notebook using the background serial function (hsersetup, etc.) on a 40X2. While waiting for the data to come in (hserinflag, hserptr), I also need to send unrelated serial data to a display attached to a different port on the 40X2. It...

    MXL90614 problems

    I'm having trouble trying to use a MXL90614 temperature sensor on a I2C bus. I've tried reading the device using I2C address $5a and all I get is 255 regardless of the memory address used for the device. I don't think the 90614 is responding at all. When I try I2C address zero the hI2Csetup...

    Help reading battery voltage

    I would like to build a device that would accurately read and display the voltage from the engine and house batteries in my motorhome. Both are 12 volt systems. I image a PICAXE board with the necessary switches and "stuff" that will select which set of batteries to read and display. My...
