We’ve got a RAK13002 in order to control a few LED components.
We need five IO pins to drive 2 x monochrome LED and 1 x rgb LED
Wire them up to IO pins 1,3,4,5,6, and all is good: except, we also have a GPS module attacehd to SLOT A … this appears to make use of WB_IO1, since without writing any code to do so, the LED connected to that pin flashes and it is (or at least appears to be) related to the GPS module reading data.
This should not be a problem since there is one more IO pin on the module, i.e. IO7 … however looking through the
variants.h header file, there is no mapping supplied for WB_IO7, and I cannot find details about the actual pin number on the IO module itself, so that I could provide my own mapping.
Has anyone used the RAK13002 and made use of IO7? How did you manage that?
