Hi,
I'm trying to configure a PWM-pin on the raspberry pi 2. I'm using
pigpio, with the demo-program.
I configured pin 12 (GPIO 18) to be a PWM pin.
When I click the PWM-button on the demo-program, the pi hangs. I have to
power-cycle to "recover".
I modified this:
REG_GPIO = $3F000;
and this :
fd := fpopen('/dev/gpiomem', O_RdWr or O_Sync); // Open the master
/dev/memory device
I'm trying to debug this :
delayNanoseconds(200); <-- breakpoint
pwmf := Pointer(LongWord(Self.FPwm)+PWM0_RANGE);
pwmf^ := $400 ; //max: 1023
delayNanoseconds(200);
pwmf := Pointer(LongWord(Self.FPwm)+PWM1_RANGE);
pwmf^ := $400 ; //max: 1023
delayNanoseconds(200);
Stepping further with F8.
When I press F8 on the first
pwmf^ := $400;
the code "singe steps" automatically, but after a number of steps the
application crashes and the pi hangs.
This is different from normally running the application where the
application just hangs after pressing the PWM-button.
Input and output works fine, as user "pi".
Any thoughts ?
Thanks,
Koenraad.
