About
This project has been inspired by all the Sony Spresense capabilities to use a new and innovative MCU that brings a powerful camera module to the developer community, the idea is to prove that by aim of the Spresense technology a new product can be developed in shorter time, using less hardware resources and with smarter and differentiating features compared to existing tools. The project was also of my interest in camera MCU designs where public previous experience work is available such as this (NXP) and this (WZ1320).
The Setup
The Sony Spresense board don't have an Ethernet peripheral which is something we need for the web camera project. There might be many options out there to provide Ethernet connectivity but not all might serve for our purpose, been the speed and large amount of data transfer our makers that need to be maximized.
Based on previous experience projects, I have found Wiznet modules great for the Job, actually the experience with other technologies shows that the camera acquisition is more of the bottleneck to have a video stream than is the Ethernet connectivity when using Wiznet modules. Another advantage of using Wiznet modules was the easy implementation either from Hardware but more important from Firmware point of view. The last is specially true when using the Arduino IDE.
For the video stream we need the Spresense module with Main board and camera module, for the Wiznet module we have choose Wiz550io.
