pa help sa Line Follower with PWM
« on: February 03, 2012, 09:44:25 PM »
ask ko lng po about sa PWM kng yung output na galing sa MCU pwde gamitin sa isang H-bridge ng LM298?? di ba dual H-bridge po yun?? kasi ang nakita ko as far is gagamit cla ng darlington or a mosfet transistor po...pero yung tanong ko kng pwde, saan ba xa malagay?? sa input ba or sa enable?? tsaka po pa2long na rin if kng cnu po meron ng sample program codes sa PWM pa share po,,enhance ko lng..wla pa kc ako alam sa interfacing sa PWM with the MCU. thanks...

in my case, if you check the data sheet, instead of placing a resistor between the current sensing pins and the ground, i place an NPN transistor and connects the base of the transistor with my PWM source,  ;D, maraming diskarte yan, eto nga lang kasi natry ko, mahal kasi etong IC kaya sa transistor H-bridge lang me.
