This is my first robot project using a uC ( excluding Mindstorms ). I am a newbie and am interfacing a PIC 16F876A ( programmed in CCS C code ) to a Texas Instruments L293DNE half H-Bridge driving a Tamiya twin-motor gearbox. I have worked out the PWM and speeds and directions, and how to coast to a stop OK.
Is it possible to brake using this configuration, or only possible to brake using one motor? If I send two HI signals simultaneously on either side of the L293D does this basically fry the chip?
