The Wireless Image Transmission System of Capsule Endoscope Based on STM32F103

摘要：

　　In order to improve the real-time and accuracy of capsule endoscope image transmission system,and reduce the system volume,this paper proposes a low-power low-cost wireless image transmission system based on SoC chips and STM32F103 embedded micro controller.We adopted the CMOS camera module OV2640 with JPEG compressed image processing and 2.4 GHz wireless transceiver chip nRF24LE1 for image acquisition and wireless transmission,using STM32F103C8 to control the wireless chip nRF24L01 and transmit to the PC via USB interface.This paper analyzed the chips structures and functions,and introduced the hardware structure and software scheme of the system.The experimental results showed that the system can get clear and stable images.
