- Mon Feb 23, 2015 8:30 pm #10571 Just thought I'd mention for those who land on this thread that the following define is faulty :

#define GPIO 0
PIN_DIR_OUTPUT = GPIO;

GPIO needs to be either 1, 2, 4, 8, etc.. depending on the GPIO you want to target.
In other words: 1 for GPIO0, 2 for GPIO1, 4 for GPIO2, etc.

Doesn't it need to be OR'd with the register value?

From the OP: 'PIN_DIR_OUTPUT [...] changes the direction of the pin to an output [...] only "1" bits written will cause a change.'
