Posted on Edited on In ,

My previous blog MaixDuino 1 briefly introduced the fundamental functionalities of MaixDuino. Today, two more functionalities are to be investigated.

1. Binocular

1.1 Hardware Cable Connection

Cable Connection

1.2 Software Verify/Compile

1.2.1 official sipeed_gc0328_binocular.ino

Sipeed provides its official sketch sipeed_gc0328_binocular.ino.

Sketch uses 321804 bytes (3%) of program storage space. Maximum is 8388608 bytes.

1.2.2 Fixing Bugs

Please refer to my pull request https://github.com/sipeed/Maixduino/pull/145.

  • Camera.h: define function flip as virtual.
  • Sipeed_GC0328.h: add the declaration of a new public funtion void flip(bool horiz, bool vert) override;
  • Sipeed_GC0328.cpp: implement the above-mentioned new function as:
1

void Sipeed_GC0328::flip(bool horiz, bool vert)
{
    gc0328_set_hmirror(horiz);
    gc0328_set_vflip(vert);
}
