Hardware: ?ESP8266 UNO v2 Core Version: ??

Description

Problem description I followed the tutorial to the dot thats on the website. I am able to upload the code. But when I open the serial monitor I'm SPI error and I don't know what I am doing wrong. please help me.

Settings in IDE

Module: ?Generic ESP8266 Module? Flash Size: ?4MB/? CPU Frequency: ?80Mhz? Flash Mode: ?qio? Flash Frequency: ?40Mhz? Upload Using: ?OTA / SERIAL? Reset Method: ?ck / nodemcu?

Sketch

// ArduCAM Mini demo (C)2017 Lee
// Web: http://www.ArduCAM.com
// This program is a demo of how to use most of the functions
// of the library with ArduCAM ESP8266 2MP/5MP camera.
// This demo was made for ArduCAM ESP8266 2MP/5MP Camera.
// It can take photo and send to the Web.
// It can take photo continuously as video streaming and send to the Web.
// The demo sketch will do the following tasks:
// 1. Set the camera to JPEG output mode.
// 2. if server.on("/capture", HTTP_GET, serverCapture),it can take photo and send to the Web.
// 3.if server.on("/stream", HTTP_GET, serverStream),it can take photo continuously as video
//streaming and send to the Web.

// This program requires the ArduCAM V4.0.0 (or later) library and ArduCAM ESP8266 2MP/5MP camera
// and use Arduino IDE 1.6.8 compiler or above

how to solve this???

[UCTRONICS]

@IoTSquad We have tested your code on Arducam ESP8266 UNO V2 board and it can work normally. Please check your hardware connection. The SPI is an error.
