UART communication problem in solar micro inverter

Other Parts Discussed in Thread: CONTROLSUITE

Hello,

I have a UART problem in Solar Micro Inverter Development Kit. Where do I find the sample code about UART? What pin can I use?

Thank you

Hi,

You can download controlSuite and can find examples here depending on your controller: C:\ti\controlSUITE\device_support

Thank you, Gautam

I look at the example, "Sci_echoback". It set GPIO28 and GPIO29 as TX and RX.
But there are not external pins in solar micro inverter.
Can I set other pins as TX and RX?
Or I have any other good methods to implement the UART communication?

Thank you.

Now I am not familiar with the solar micro inverter from TI. But I can see that it is shipped with the TI 28035 isolated control card (ISO).

This card is equipped with a USB JTAG connector which probably also features a USB SERIAL (pops up as a virtual COM port in Windows).

And it probably uses GPIO28+29 for serial comm.

Hi,

As Mad mentioned, the Isolated ControlCARD does have the UART signals brought to the USB JTAG. This is the optimal and safe place to connect since it is isolated from the main power stage.

You can connect this port with the terminal program of your choice.

Thanks,
Mark
