hi every1,
I'm trying to use the 34 pin GPIOs I'm unable to access the
25,26,27,29,30 which belongs to GPIOE register and base values are
128,129,130,131,132 respectively
i tried the following comands to drive a LED in linux terminal
echo "128" > /sys/class/gpio/export
echo "out"> /sys/class/gpio/gpio128/direction
( then thers no output I mean Led is not ON )
but where as I tried with the 28th pin GPIOG2 with a base values of 194
echo "194" > /sys/class/gpio/export
echo "out"> /sys/class/gpio/gpio194/direction
//the LED is ON
echo "in"> /sys/class/gpio/gpio194/direction
// LED is OFF
so can any1 guide what might be the problem
is the pin connections wrong or is the GPIOE doesnt support or what is that
exactly I need to do to use the GPIOE pins I mean 25,26,27,29,30 of the
34pin GPIO connector
thanks in advance,
ARMtry.
problem with GPIOE on 34 pin connector
If you use SPI or I2C then this pins are used by drivers and couldn't be driven by gpiolib. But not 100% sure.
