Hi, We are trying to make a driver using L298 and L297. At the beginning, we used the L298 and produced the pattern wave drive (single phaseon) using the printer port . Then when we used the L297 as a phase pattern generator it was working on the Normal drive mode ( two phase on ). We have studied the data sheet, but we didn’t find out : How could we set the L297 on the wave drive mode ? Any help would be greatly appreciated.
