一种基于MSP430的电子耳蜗接收刺激器设计
摘要
电子耳蜗是一种可以使重度耳聋患者恢复听觉的医学装置
接收刺激器是其中的关键组成部分
设计了一种基于MSP430和nRF2401的电子耳蜗接收刺激器方案
它利用MSP430微控制器作为系统的控制核心
控制nRF2401收发芯片来实现信号的准确接收
并对接收到的信号进行CVSD解码
根据解码得到的控制信号产生强度和频率可控的双相刺激脉冲。
Abstract
Cochlear implant can restore partial hearing of profoundly deaf people.As an important part of cochlear implant
stimulator can receive signals from the signal processor
generate diphase pulses
and those pulses’intensity and frequency are controllable.The strategy of a stimulator which is based on MSP430 and nRF2401 is described.It can receive signals real and truly by nRF2401 with MSP430’s control
and then decode them by CVSD.It also can generate right diphase pulses whose intensity and frequency can be controlled.
