CCS/CC2650: System_printf() not displaying correctly

Thank you for the help!

I for the life of me I do not understand what could be wrong. I believe I should be connecting to the COM8 port in the terminal.

I have it set to a baud of 9600, with the data size, parity and stop bits set to 8, none and 1 respectively. 

It shows that it is connected (or at least that it doesn't have issues)

Here is the current code that I have that is trying to access the UART display stuff:

  // Includes
  #include <ti/mw/display/Display.h>

  // Globals
  Display_Handle dispHandle = NULL;
  Display_Params params;

  // Inside SensorTag_taskFxn()
  Display_Params_init(&params);
  params.lineClearMode = DISPLAY_CLEAR_BOTH;

  dispHandle = Display_open(Display_Type_UART, &params);
  if (dispHandle) {
      Display_print0(dispHandle, 0, 0, "Hello Serial!");
  }

I currently initializing this display code within sensortag.c inside of SensorTag_taskFxn(). Is this this a poor way of doing this? I have no idea at this point.

"dispHandle" returns 0 which I would assume means that the display port cannot be opened, If that is helpful.

I was working with the C:\ti\simplelink\ble_sdk_2_02_02_25\examples\cc2650stk\sensortag. I am going to try to get C:\ti\simplelink\ble_sdk_2_02_02_25\examples\cc2650stk\simple_peripheral to work right now though to see If I have better luck. I have also been swapping back and forth between 9600 and 115200 for baud rates to see if either work.

I can't seem to find the online link anymore for the sensortag code

Thom,

Can you please confirm the Display example works to rule out any setup issues?

Todd

Yeah, I am having troubles finding what could be missing between Simple_peripheral and the Display example. I was actually able to finally get the Display example working locally. I am initialising Display_open at the end of SimpleBLEPeripheral_init inside of simple_peripheral.c

Am I doing something wrong? I don't understand this is driving me crazy. Could there be a build setting I am missing?

This is my simple_peripheral.c file:

I have absolutely no idea at this point. The Display example, as I have said, works with no problems. And to the best of my ability, I have checked that everything has the same settings and implements the same code but it is 100% possible that I have overlooked something.

Your thoughts on what this might be would be wildly appreciated.

Thanks for you continued help and support

Probably if I would have known what I was looking for to begin with I would have solved it quicker but, again, super newb, so it's probably just apart of the process.

This wiki is where I found the first mention of Display_DISABLE_ALL aside from finding it mentioned in the Display.h file.

Then searching for Predefined Symbols I came across the location to change it lower in the wiki page

Thanks again!
