Recently I develop one project in which total 5 DC motor. The project contain 16x2 LCD display with PIC16F886. When use press key then motor will run. I observe that after some key operation LCD show garbage & it remain few minute. LCD runs in 4 bit mode. Garbage comes randomly some times for 3 iterations some times for 10 iterations and this design is done on the PCB board. Please let me know what could be the problem.
I have 0.1uF cap across the PIC IS also.
To drive motor I have used L298n H-bridge IC. I have used flywheeling diodes also across the motor connection.
