TMS320F28069: F28069

Part Number: TMS320F28069


Hello all,

We are currently working with the F28069 controlStick and would like to supply the controlStick with an external power source. We have a buck converter which converts our voltage from 15V to 5V. On the PIN-OUT TABLE of the F28069 there is the GPIO16 with 5.0V but it´s disabled by default. Does anybody know how to active this pin or is this pin permanently switched off? 

Thanks in advance.

    Dominik,

    Please confirm that you are using the controlSTICK and not the ControlCARD.

    If you are using the ControlSTICK you can supply 5 V to pin 16 of J1 (this is not GPIO16 of the F28069 MCU marked as U2 on the schematic). You will need to place a 0-ohm resistor at R15 to connect it to the 5V0 net of the controlSTICK. Once you connect R15, and supply 5 V to J1, do not connect the 5 V from the USB.

    Yes we are using the controlSTICK. We soldered a 0-Ohm resistor to R15 and now it is working. Thanks.
