undefined reference to `shiftOut'

[goran-mahovlic]

adding this to ino works
but I do now know where to place it

void shiftOut(uint8_t dataPin, uint8_t clockPin, uint8_t bitOrder, uint8_t val)
{
uint8_t i;

 for (i = 0; i < 8; i++)  {
       if (bitOrder == LSBFIRST)
             digitalWrite(dataPin, !!(val & (1 << i)));
       else      
             digitalWrite(dataPin, !!(val & (1 << (7 - i))));

       digitalWrite(clockPin, HIGH);
       digitalWrite(clockPin, LOW);            
 }

}

There's already an implementation in hardware/arduino/avr/cores/arduino/wiring_shift.c. Perhaps this could work, most probably even without any modifications if copied to hardware/fpga/f32c/cores/f32c?

now I got I probably need to fix .h file

copy wiring_shift.c to hardware/fpga/f32c/cores/f32c, and changed all uint8_t to uint32_t in wiring_shift.h

and got it working without errors, so you can fix it on repo

[goran-mahovlic]

and now
https://github.com/wayoda/LedControl
is working to :)

[goran-mahovlic]

all is working now with json
