P0.15 can not be seted to High levlel

Posted on January 06, 2006 at 01:02

I use keil for arm

GPIO_Config(GPIO0, 1<

GPIO0->PD |= 1<

GPIO0->PD &= ~(1<

in keil IDE, i can get High/low level. (I/O Port 0 Dialog box)

But i can not get High level at P0.15 Pin, it is low level always.

How can i do ?

Hi shangdawei,

As the STR71x datasheet P0.15 is only an input pin.

With best regards,

Hichem ;)
