Error uploading sketch to Digispark

Projects Programming
1

Hello everybody,

I'v got a couple of Arduino nano's which I am learning the basics on. I just started this whole arduino thing and grasp the basics.

Now I've get a 433mhz rx/tx set and a bit of simple code

#include <RH_ASK.h>
#include <SPI.h> // Not actualy used but needed to compile

#define relay 7

RH_ASK rf_driver;
RH_ASK driver(2000,6); //"2000" standaard snelheid, pin nummer

void setup(){
  
pinMode (relay, OUTPUT);
rf_driver.init();

}

void loop(){

  uint8_t buf[1];
    uint8_t buflen = sizeof(buf);
    if (rf_driver.recv(buf, &buflen)) // Non-blocking
    {
      int i;
      // Message with a good checksum received, dump it.
      
  for (i = 0; i < buflen; i++)
  {
   int c = (buf[i]); 

if (c==49){
  digitalWrite(relay, HIGH);
 
}

else {
  digitalWrite(relay, LOW);
}
  }
    }
}

Even though it looks like a mess (incorrect spacing, enters and placement of brackets and such) it works fine on my Nano!

Now I thought: this can be smaller, so I ot myself a Digispark. I tested this with my i2c lcd 16x2, printed a hello world, made a led blink, measured some temperature. all fine.
But when I want to upload above sketch it gives me an error....

Arduino:1.8.7 (Windows 10), Board:"Digispark (Default - 16.5mhz)"

Fout bij het compileren voor board Digispark (Default - 16.5mhz)

It is quite a bit of error... and I have no clue what it means! Who could shed some light on this?

It seems to bog down on the spi library, but i wouldnt know how to fix this :frowning:

Kind regards,

Tim

The Digispark uses the AT Tiny85 which does not have built-in SPI support. The nano is based on the AT '328 which does. Are you sure you are compiling this sketch for the proper MCU?

I am awere of the different chipsets.

I added the attiny/digispark to the Arduino IDE. It has worked fine so far.

looking at the pinout of the module it seems to have SPI?

or am i misunderstanding something?

Is there a workaround so that i can still use my digispark, despite the SPI lacking?
