Hi,
we are working on a board re-design to use the Wireless Shell V3, and we noticed that the
Vext_Ctrl is connected to the hardware SPI_CLK pin.
Since we also use the Vext pin to turn ON/OFF some ICs on the board, it is important to keep it working at the same time we use SPI.
Unfortunately the documentation from the V3 does not contains much information about Vext_Ctrl.
What exactly do this Vext_ctrl pin does? How does it interfers/controls the Vext use? Do I have to re-map the SPI_CLK to another pin, in order to use the Vext and SPI?
Many thanks in advance!,
Nathan
