Ble hal gpio programming

Other Parts Discussed in Thread: CC2540

I've got my ble program working on cc2540 and it can now talk to android mobile phone. But now I try to control p2_0 on the smartrf module by setting

1. P2 to GPIO mode

2. P2 to output mode

3. P2_0 =0x1

But p2 output remains low

Why?

Anything i need to set to be able to control GPIO pins directly from simpleperipheral.c?

Hello,

I would suggest looking at the keyfob example project, you can see how GPIO is used.

Best wishes

P2_0 was used by something else on board, so it got stucked. So I borrowed P1_4 (used to control LED output) for my purpose, and it works fine now.
