Good evening, after build in the linux zedboard. I want to turn the LEDs without the write_led . with a Linux application in the SDK tool:
using the port in the file system.ucf
Net processing_system7_0_GPIO <7> LOC = T22 | IOSTANDARD = LVCMOS33;
Net processing_system7_0_GPIO <8> LOC = T21 | IOSTANDARD = LVCMOS33;
Net processing_system7_0_GPIO <9> LOC = U22 | = IOSTANDARD= LVCMOS33;
Net processing_system7_0_GPIO <10> LOC = U21 | = IOSTANDARD =LVCMOS33;
Net processing_system7_0_GPIO <11> LOC = V22 | = IOSTANDARD =LVCMOS33;
Net processing_system7_0_GPIO <12> LOC = W22 | IOSTANDARD = LVCMOS33;
Net processing_system7_0_GPIO <13> LOC = U19 | = IOSTANDARD =LVCMOS33;
Net processing_system7_0_GPIO <14> LOC = U14 | = IOSTANDARD= LVCMOS33;
I don't no if the port using is correct or not?
# include "xgpio.h"
# include "xparameters.h"
int main ();
{
xgpio LED;
XGpio_Initialize (& led, XPAR_PS7_GPIO_0_DEVICE_ID);
XGpio_SetDataDirection (& LED,1,x0000)//i can find the right mask derection Bits 7-14
XGpio_DiscreteWrite (& LED,1,0xffff);
return 0;
}
thank you :)
