RTOS/TM4C1294NCPDT: GPIO function calls in Tiva C series EVK

Hello Manohar,

For starters, have you looked through the TI RTOS Driver API's? You can find the document link for them in [Install Path]\tirtos_tivac_2_16_00_08\docs - look for Documentation_Overview_tivac.html

In general, the index should be the Pin you are trying to configure, and PinConfig should be the settings for it. The PinConfig input should be based on the #define's in GPIO.h which start with "GPIO_CFG_"

Hi,
I am still not aware of what is the argument called index, that have to be passed in every GPIO function calls.
Whether it is a PORT base address? If it is a Pin number? what exactly should I give ?
Example for PA3 to configure as output pin, I should give index as 3 or Microcontroller pin number 36?

What exactly should I pass in GPIO index?




Regards,
Manohar.

Hello Manohar,

I am not really ramped on the TI-RTOS side of Tiva yet so for the immediate moment I encourage you to look at existing examples and the documentation to see if you can find some more clarity. Another useful document may be: http://www.ti.com/lit/ug/spruhd4m/spruhd4m.pdf I will see if some more knowledge about the workings of TI-RTOS can explain what you need to do in a more layman manner than my initial attempt.

Also consider looking into: https://training.ti.com/ti-rtos-workshop-series

Robert - FYI the API calls listed by Manohar are for TI-RTOS supporting Tiva-C, not TivaWare, so that link won't provide any useful info when comparing it against what needs to be done for TI-RTOS.
