TMS320C5515 EVM pin J13.15 Multiplexing

Other Parts Discussed in Thread: TMS320C5515, ADS1298R, PCA9536, ADS1298

Hi All,

I am trying to connect TMS320C5515 EVM with ADS1298R, and currently I am looking at C5515's Technical Reference:

e061fbebec6d447d3f7f9211c713161a.jpg

I can see here that there is only INT1 connected to pin J13.15, and in my application I don't find it necessary to use interrupt, so I am wondering is anything else besides INT1 multiplexed to J13.15.

Thank you for answering.

    Hi Darko,

    Sorry, INT1 cannot be multiplexed with any other signal.

    We built an ECG daughter card that attached to these headers a long time ago (now discontinued). For that design, we connected the INT1 interrupt signal to receive interrupts from a PCA9536 I2C IO expander.

    The only other signals between the ADS1298 board and C55x were SPI, I2C, and GPIOs.

    There are some unconnected pins that you could blue-wire a signal to: J14 pins 10, 12, 14, 15, 16, 18, 20 and J10 pins 1, 2, 3, 4, 6, 8.
    Maybe you can blue wire from a resistor, jumper, or test point to one of these headers.
