使用timer.setinterval出現無法轉換的問題

想要使用blynk接收訊息,但是在使用timer.setInterval(1000L, Show_Acc);會出現以下error:invalid conversion from ‘void ()(int)’ to 'timer_callback {aka void ()()}’ [-fpermissive],請幫我看一下哪裡出了問題,謝謝。

void setup(){
Wire.begin();
Serial.begin(115200); // start serial for output. Make sure you set your Serial Monitor to the same!

delay(500);
Serial.println("\nSetup, init");
Blynk.begin(auth, ssid, pass);

timer.setInterval(1000L, Show_Acc);
I2C_Bus_Check();

YAL210_Initial(YAL210_I2C_Addr);

Serial.println("\nStart loop");
}

void loop(){

Show_Acc(YAL210_I2C_Addr);
Serial.println();
delay(100);
Blynk.run();
timer.run();
}
