HI, I am using P89v51rd2 to control L293D. My code is running on Eval board but not on the circuit I designed (all ports are reset to High state and code is not running). I used P0.0-P0.3 for input, P2.0-P2.3 as output. only other connection is 11.0592MHz xtal with 33pF caps. Please let me know what to do Regards, FD
Identify and correct any design and implementation issues?
Designing is just 4 inputs on port 0, 4 outputs at port 2 and on oscillating circuit with 11.0592 MHz and 33 pF capacitors. One Reset circuit with 0.1uF capacitor in parallel with switch and 8.2K resistor for Pull down at reset pin.
