GPIO Alternate Functions Definitions for HE910

2 thoughts on “GPIO Alternate Functions Definitions for HE910

  1. Hello, I’m using the HE910 and want to make use of the GPIO and Python scripting.  From what I’ve learned interrupts are not support but polling should work.  Also, GPIO_01 has been assigned for modem activity and I’ve been told GPIO_08 and _09 are good candidates for I2C.  Are there any other alternate functions I should know about?  The documentation has a bunch of N/A’s for the HE910 and I wanted to be sure I can safely use the other GPIO pins for general IO without adversely affecting behavior of the module.  Thanks.

    1. Hi Al,

       

      Python 2.7 in HE910 has GPIO custom module implemented; in Hardware User Guide the GPIO specific paragraph has a list of all available GPIO pins and their logic levels, indeed all are dedicated GPIO less GPIO_01 which is set to STAT LED alternate function.
