Basically, I want to use SPI for a couple of devices. That means I need 2 chip selects. The TM4C provides:
SSInClk
SSInRx
SSInTx
SSInFss
SSInFss is available to use as a dedicated chip select (CS) for each port, with timing to enable/disable as needed. But, if I want to use 2 chip selects, it doesn't look like I can use the SSInFss, because it gets activated automatically, and would not allow me to use a 2nd GPIO for CS. Can I just use two GPIO's and bit-bang the levels as needed?, ignoring the
Is there a better way?
