Conflict with CCS811 #41

Closed blazeis closed 4 years ago

blazeis commented 4 years ago

Hello. I cant init ccs sensor if mcp2515 initialized. Minimal code is:

#include <SPI.h>
#include <mcp2515.h>
#include "Adafruit_CCS811.h"

Adafruit_CCS811 ccs;
MCP2515 CAN0(10);

void setup() {
  Serial.begin(115200);
  if(!ccs.begin()){
    Serial.println("Failed to start sensor! Please check your wiring.");
    while(1);
  }
}

void loop() {
  delay(5000);
}

if i comment out line "MCP2515 CAN0(10);", sensor initializing properly. Sensor connected to i2c bus. Arduino pro mini, atmega 328p 5v 16MHz.

MCP2515 is using SPI, CCS811 is using I2C, please check the PIN being used shouldn't have conflicts.

Thank you for reply. At this morning, i check wiring twice. I soldered CS from mcp2515 to pin 10 on the arduino's front side, and wake pin from CCS811 on the arduino's back side. Sorry ¯_(ツ)_/¯
