Dearly Beloved,

This is Ruben.

I am designing a Combat robot.
I need a program to generate the PWM with variation in the duty cycle.
When a switch is pressed Duty Cycle should increase and decrease when another switch is pressed.
I need this program to control the speed of motor.

Kindly, Give your suggesstions

With expectation,
BEN
 

Please post schematic and / or other details.

You can use timer in mode 1 and the value in TH and TL should be loaded using some variable and this variable value will increase or decrease with action of button.
and donot do increment or decrement in steps of one do it in steps of 1000-5000
 

Here is the transmitting section of my project
