Hi,
I'm trying to configure SPI interface between LM4F120HQR Launchpad and CC3000 boosterpack.
CC3000 boosterpack SPI inputs (RX TX and clock) are equivalent to PB4 (clock) PB6 (RX) and PB7 (TX), which is SSI2.
So far so good.
The thing is PB5 is the ENABLE pin in the CC3000 boosterpack. This is the pin that enable CC3000 device.
The problem is that PB5 is also FSS in the SSI2 interface.
This pin is somehow pulled down and won't allow ENABLE to be configured.
I don't use the FSS (I did not configure this pin as part of the SSI2 interface configuration) but it still seems to be pulled down.
Can I use this pin for other purpose then FSS? I need it to enable the CC3000 device.
If so, how can I do it?
Appreciate your help on this issue.
Yael
