The aim of this project is to build a wireless endoscopic system based on the Wi-Fi technology, in case to make this medical equipment available in much more circumstances. The core idea is to cope with the problem that the traditional endoscopic used before is inconvenient since there must be a dedicated receiver which is made on purpose. With the popularity of mobile intelligent terminal, the Wi-Fi based wireless transmission technology could make it easy to use the common Android mobile phone or iPad as the endoscopic receiver. In this project, we take CC3200 as the MCU of endoscopic system which integrates the Wi-Fi module in one chip.
