    Timer1 module modified for 28X2

    This module enables you to time events in milliseconds using Timer1. It is the module written by Jeremy Leach but I've amended it to work on the 28X2. #PICAXE 28X2 #rem # ####################################################### # TIMER1 test code #...

    Basic electronics question - GPS enable

    I know this is probably a very simple question to most of you on this forum but I'm new to electronics and we all have to start somewhere! I want to use a Picaxe pin (e.g C.5 on a 28X2) to switch a GPS module on and off. The instructions for the GPS module says there is an enable pin...

    MinIMU-9 v2 Gyro, Accelerometer, and Compass (L3GD20 and LSM303DLHC Carrier)

    I am trying to read the subject IMU. The datasheets are at http://www.pololu.com/catalog/product/1268/resources. I've started by just trying to read the gyro. I've read the WHO_AM_I register and I get $D4 which is correct. However, when I read the X, Y and Z registers, their values do not...

    28X2 and i2c problems

    I am using the PICAXE development board (AXE091). I have installed the DS1307 RTC and put a battery across pins 3 and 4. I am trying to set the date/time and then read it. I can get it to work with an 08M2 with pin 5 (C.2) connected to the hi2c sda header and pin 6 (C.1) connected to the hi2c...
