Other Parts Discussed in Thread: OMAPL138

Hey,

  I Have a problem with assigning the pins of OMAPL138 for the PWM's. Im not able to test the Pwm directly from the Logic PD EVMOMAPL138, So kindly reply for my post that Whether there is any Alternative pins to  test the Pwm's. 

Thankyou,

Raju CM

    Hi Raju,

    There is one way to test the EPWM1A & ECAP2_APWM2 PWM pin from the base board is across the U25 device (SN74AVC16T245DGG) the bus transceiver at pin no 36 & 46, basically this pin is used to adjust LCD back light power and LCD_PWM, but you can disable the bus transceiver by make the S7.1 OFF and Solder a wire form the U25.36 or U25.46 IC terminal and test EPWM1A & ECAP2_APWM2 status.

    Regards

    Antony
