Intellectual 290 points

Part Number: TMS320F2800137
Other Parts Discussed in Thread: SYSCONFIG

Hi, we are designing a motor controller with the device above and would like confirmation of pinouts for PWM, Encoder, Current sense, and SCI signals. Please review and give feedback.

PWM (3 phase)

PWM_UH: GPIO16 (33)

PWM_UL: GPIO17 (34)

PWM_VHI: GPIO227 (24)

PWM_VLO: GPIO230 (25)

PWM_WHI: GPIO41 (55)

PWM_WLO: GPIO40 (53)

Encoder (quadrature, 3 hall)

ENCODER_A/U: GPIO20 (27)

ENCODER_B/V: GPIO21 (28)

ENCODER_Z/W: GPIO13 (29)

Current sense

ISENSE_U: A12/C1 (18)

ISENSE_W:  A1 (14)

SCI for XDS110 debugger

SCI_RX: GPIO3 (49)

SCI_TX: GPIO8 (47)

Please review these and let me know if I made any errors. 

Thanks in advance for the feedback.

    Hi Binil,

    There are some resources and tools to help you review these and sanity check your settings, so that you can be sure you muxed this properly:

    1. I would highly recommend you use Sysconfig to see if these are the right GPIOs and peripherals. You can add your various periopherals and see if they are on the right GPIOs that way. Even if you don't use Sysconfig to create your code, you can use it to verify this.

    2. The "GPIO Muxed Pins" part of the datasheet also has this information.

    Regards,

    Vince
