Variable frequency PWM using MikroC + PIC16F887

Anonymous - 10:33 PM 3 Edit
When I was doing a project on a robot,I found out that the MikroC PWM library doesn’t support variable frequency values for the PWM frequenc...

Simple 3.3V–5V level shifter

Anonymous - 9:42 PM 27 Edit
In present day electronic we find many sensors or modules working in 3.3V logic levels.In other terms LVTTL devices (Low-voltage TTL). But e...

PS/2 Keyboard Interface for PIC uC (PIC16F887)
