East a bit..
Well after much hair pulling head bashing and general frustration I've finally got my hand controller communicating with the motor driver.
So you choose 'slew mode' and press the east button, and the motor starts slewing east, let go and it immedaitely resumes its normal tracking, press west and it turns to the west.
Might seem simple but it's been anything but. Two completly seperate chunks of code in two seperate PICs. The first PIC scanning a keypad for finger presses, interpreting modes double key presses etc., communicating down a 2meter I2C comms link, interpreted by another PIC and then the correct motor instructions sent over the same I2C wires to the motor drivers.
Not straight forward.. but adding the GOTO commands will be no more than a couple of evenings work, essentially that's how the slewing is working now, it's slewing the target point and the motor is playing catchup. Autoguide port?.. childs-play.
And I've just confirmed, it's hot plugable.
Am I happy... of course.:D
Do I expect anyone else to follow what I'm on about.. :o, maybe not.
never mind
