Hello,

I would like to be able to change the logic level of a few IOs by
either writing to GPIOs pins or reading their state level.

I used this sample code :

int fd = open("/dev/mem", O_RDWR|O_SYNC);
char *gpioregs;
gpioregs = (char *)mmap(o,4096, PROT_READ|PROT_WRITE, MAP_SHARED, fd,
0x12c00000);
gpioregs[0] = 0xff;
gpioregs[2] = 0x12; //1 on DIO_1 and DIO_4 and zero on others

could someone help me with that ? I tried this and I see no changes on
the outputs levels on DIO_1 and DIO_4.

I hope someone can help.
Thanks

Yan~
