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
and now https://github.com/wayoda/LedControl is working to :)
all is working now with json
if I try to use simple code for nokia display I got this error I have seen this error on multiply examples
