Spurkfun Edge and Camera

My Arduino settings and code to use Sparkfun Edge with the camera module.

Hardware

• Sparkfun Edge (Input only 3.3V.)
• Himax CMOS Imaging Camera – HM01B0
• Wemos CH340G USB to serial (Make sure it output is 3.3V!)

In Arduino IDE

• Add Boards Manager URL: https://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/package_sparkfun_index.json
• Install SparkFun Apollo3 Boards package
• Install SparkFun Himax HM01B0 Cameras library

Settings

Upload sketch

• Press and hold the Reset button
• Press and hold the 14 button
• Release the Reset button
• Hold the 14 button and hit Upload in the Arduino IDE

If it is successful you will see this message:

Read images

Board default Serial Baudrate is 460800.

Example Python code is utils/StopMotion.py.

Run this to save images on same directory:

./StopMotion.py -p /dev/ttyUSB0 -o .

First you see something this. When I first tried this it was all I get. Only these numbers forever. Then on the next day I came back, hooked it up and miraculous it started to work.

Positive output
