hi, me n my partner is trying to develop a window climbing robot using the PIC 16F877A to control its operation.
Im wondering, since the PIC 16F877A has only 2 pwm, n i dun intend to control the speed of the robot which in dat case, pwm have to be used. here, i only need to control the angle of rotation for 3 motors.
we wanted to develop something almost similar to below for our final project (we use this as our reference, and this is where we got the idea from):http://www.mech.utah.edu/~minor/publications/IROS00-climber.pdf
if we need to use the pwm, we need 3 pwm. however, in PIC 16F877A they only have 2 pwm... does dat mean that i have to use 2 Chips of PIC116F877A???
