Servo4 Module

Posted on Feb 5, 2014

In pure servo mode, it is expected that up to 4 unmodified servos are attached to the board. The four servos can be independently controlled. There is current feedback on all four servos. In differential steering mode, the module can control up to 4 servos. The first two servos are expected to be servos that have modified been for continuous rotat

ion. The second two servos are regular unmodified servos. The first two servos have current feedback and the second two servos do not. There are two trim pots that are used to set the no rotation condition for the first two servos. In differential steering calibration mode, N10 is jumpered upward and it causes yellow LED D1 to light. It causes both servos 0 and 1 to be enabled. The value of trim pot R5 to be sent to servo 0 and trim pot R6 to be sent to servo 1. The purpose of calibration mode is to allow you to adjust the two modified servos that are connected to servo 0 and servo 1 and adjust them until they stop rotating. This frees the programmer from having to experiment to find the `position` number for each servo that corresponds to each servo being motionless. The values of the stop value are read out using the Read Current Draw command for servo 2 and 3.
