Hello . I was wondering if i can use a 2nd Axe 027 cable on the same computer. I'am using Robot Basic on my PC to send and receive data
to a picaxe 40x2. I would like to add a 2nd picaxe to my project. Would another com port be assigned to the 2nd Axe 027 cable or could a conflict arise?
Two cables can be connected as Andrew indicates.
But since you are then programming two PICAXE chips and can only have one instance of the PE running at a time you will need to flip to the other program window and maybe include a #PICAXE xxx directive if they are different.
Since you would also need to change the comm. Port, rather than purchase a second AXE027 cable you could use a DPDT switch after the on-board stereo socket to select which PICAXE you program. So just flip the switch instead of selecting the right comm. Port on the PC.
In fact if labelled, there would be less likelihood of downloading program to the wrong PICAXE than if the cables were crossed or the wrong Comm port selected.
You would need the two programming circuit resistors in place for both PICAXE chips.
Then for RobotBASIC control and data collection you could channel all comms through one of the two PICAXE chips.
