Maybe your like

I've used an Arduino Nano with SPI.h to make a SPI Slave. Now I have the Nano 33 BLE and want to use the same code, but there are Errors when I build the file. Does anyone have an idea what's the issue?

The Code:

#include <SPI.h> volatile byte c; volatile byte command = 0; void setup (void) { // have to send on master in, *slave out* pinMode(MISO, OUTPUT); pinMode(MOSI, INPUT); // turn on SPI in slave mode SPCR |= _BV(SPE); // turn on interrupts SPI.attachInterrupt(); Serial.begin(115200); } // end of setup // SPI interrupt routine ISR (SPI_STC_vect) { c = SPDR; Serial.println(SPDR); //SPDR = 8; } // end of interrupt service routine (ISR) SPI_STC_vect void loop (void) { if (digitalRead (SS) == HIGH) command = 0; } // end of loop The Error: src\main.cpp: In function 'void setup()': src\main.cpp:15:3: error: 'SPCR' was not declared in this scope SPCR |= _BV(SPE); ^~~~ src\main.cpp:15:3: note: suggested alternative: 'SPI' SPCR |= _BV(SPE); ^~~~ SPI src\main.cpp:15:15: error: 'SPE' was not declared in this scope SPCR |= _BV(SPE); ^~~ src\main.cpp:15:15: note: suggested alternative: 'SPI' SPCR |= _BV(SPE); ^~~ SPI src\main.cpp:15:11: error: '_BV' was not declared in this scope SPCR |= _BV(SPE); ^~~ src\main.cpp: At global scope: src\main.cpp:24:5: error: expected constructor, destructor, or type conversion before '(' token ISR (SPI_STC_vect) ^ *** [.pio\build\nano33ble\src\main.cpp.o] Error 1
