RTOS/TM4C1294NCPDT: TI-RTOS GPIO Port Read API available?

svl123

Part Number: TM4C1294NCPDT

Tool/software: TI-RTOS

Hello,

I am using GPIO's inside a TI-RTOS application. For individual GPIO manipulations I am using the functions inside GPIO.h but would also like to read entire ports at once (i.e. return 8 bit value of input port using a single API call.) Is this possible to do using an API (without using HWREG)?

Thank you,

Hi,
Thanks Peter. Peter provided the TivaWare API to read the entire port. In the TI-RTOS's GPIO drivers I do not find method/API to read the entire port. Here is the link to TI-RTOS GPIO drivers. software-dl.ti.com/.../_g_p_i_o_8h.html

I have noticed some adversity or hesitation to mixing vanilla TivaWare with the RTOS TivaWare lately. Ralph gave some insight here: e2e.ti.com/.../2453275

Ralph intended to gather more insight, but topics like this can trail off...

Peter, your answer is very helpful and this basically answers my question because I've also wondered which API's are the "correct" ones to use in a TI-RTOS application. Thank you for clearing it up.
