TMS320F280039C: Pin voltage of pins in the TMDSHSECDOCK docking station

SRI RAM M A

Part Number: TMS320F280039C
Other Parts Discussed in Thread: TMDSHSECDOCK, SYSCONFIG, C2000WARE

Hello ,

I have TMS320F280039C control card and the TMDSHSECDOCK docking station. I ran a LED blinking model from simulink to blink the D1 and D2 leds in the control card. These LEDs are connected to GPIO pins i tried measuring the voltage across the pin 31 of the docking station and got just some noise. I am expecting a 5V or 3.3v voltage in the pin 31 on which the LED is connnected. Is my assumption right? attached a pic the setup.

Thank you

Hello,

Thanks for your question. As shown in Sysconfig, the LED D1 and D2 are connected to header pin 82 and header pin 86 respectively.

The same is shown in the EVM User's Guide:https://www.ti.com/lit/pdf/spruiz4

This guide shows that D1 is connected to GPIO31, and GPIO31 is on header pin 82.

Regards,

Vince

Thanks for the reply . Where can I find the sys config file? Is it in the c2000ware folders?

Hi,

You can either open in Code Composer Studio a C2000Ware example that has Sysconfig support in it (look for examples that also have a ".syscfg" file).

-OR-

You can browse Sysconfig on the web at: https://dev.ti.com/sysconfig

Then choose "C2000 Sysconfig" and your particular board:

Regards,

Vince
